Languages and regional variations are dealt with by the +%\styfmt{datetime2} language modules which are independently +%maintained and installed. Make sure that when you install +%\styfmt{datetime2} you also install the required \styfmt{datetime2} +%language modules. +%\end{abstract} +% +%\tableofcontents +% +%\chapter{Introduction} +%\label{sec:intro} +% +%I~wrote the original \styfmt{datetime} package back in the 1990s as +%an alternative to the \sty{ukdate} package, which had dropped out of +%some of the TeX distributions, so it was designed specifically for +%UK date formats.\footnote{Of course, \texttt{ukdatetime} would've +%been a better name, but the 8 dot 3 filename restriction was a concern back +%then.} However some users found the time formats useful +%and the ability to save dates for later use, so when \sty{babel} +%came along I~had a number of requests to make \sty{datetime} +%compatible with \sty{babel} so that the regional date formats were +%preserved but the other \sty{datetime} functions could be used. +%Then PDF\TeX\ came into existence and its \cs{pdfcreationdate} now +%provided a~way of obtaining the seconds and time zone, which can't +%be obtained from \TeX's \cs{time} primitive. Over time, the +%continual updates to the package has started to put a~strain on the +%original na\"ive \LaTeX\ code of my first package, as it's been +%stretched well past its intended design. +% +%The other problem with \sty{datetime} is that some of the commands +%aren't expandable but some users want to be able to use them in +%expandable contexts (such as, for example, PDF bookmarks or writing +%a date stamp to an external file) or they +%want to be able to upper case the first letter if the date comes at +%the start of a~sentence. This isn't an issue in English, as the +%weekday and month names are proper nouns and so automatically start +%with an upper case letter, regardless of where they appear in +%a~sentence. Users who don't know the history and original purpose of +%the \sty{datetime} package are puzzled as to why the defaults are +%all UK English or some styles were hard-coded, and some users are +%confused as to the ordering of the day, month and year parameters. +%In addition, some command names were incompatible with other +%date-related packages, but renaming those commands would break +%compatibility with older documents. +% +%In order to address all these issues, a~replacement package is +%necessary. Your old documents that use \sty{datetime} should +%still be able to compile, but for your new documents, you may prefer +%the improved \styfmt{datetime2} package instead. +% +%\chapter{Example Usage} +%\label{sec:examples} +% +%\begin{verbatim} +%\documentclass{article} +%\usepackage{datetime2} +%\begin{document} +%This PDF was created on \today. +%\end{document} +%\end{verbatim} +%In the above example, the date is displayed in the form: +%\begin{display} +%\DTMsetstyle{default}\DTMusedate{gmt} +%\end{display} +%This is the \style{default} style. +% +%\begin{verbatim} +%\documentclass{article} +%\usepackage{datetime2} +%\begin{document} +%This PDF was created on \DTMnow. +%\end{document} +%\end{verbatim} +%In the above example, the full date, time and time zone is displayed +%in the form +%\begin{display} +%\DTMsetstyle{default}\DTMuse{gmt} +%\end{display} +%or +%\begin{display} +%\DTMsetstyle{default}\DTMuse{bst} +%\end{display} +%\emph{unless} you are using \XeLaTeX\ in which case the seconds and +%time zone are omitted.

The day of week number may +%be \texttt{-1}, which indicates that the style should ignore it. +%(Some styles always ignore the day of week, regardless of its +%value.) This command is intended for use in expandable contexts +%(such as writing the date to another file or using the date in the +%bookmarks) and is used by \cs{today}. The date styles should ensure +%that any fragile content is protected. (This is why the \meta{dow} +%isn't an optional argument otherwise the command wouldn't be +%expandable.) +% +%Some styles may start the date with a word (such as the day of the +%week name or the month name). In English, proper nouns are +%capitalised regardless of where they appear in a~sentence but some +%languages use lower case month or day of week names. In this event, +%if the initial letter needs to be capitalised then you can use: +%\begin{definition}[\DescribeMacro\DTMDisplaydate] +%\cs{DTMDisplaydate}\marg{year}\marg{month}\marg{day}\marg{dow} +%\end{definition} +%which is analogous to \cs{DTMdisplaydate}. Styles that are +%unaffected by this issue (for example, numerical or English dates) +%set \cs{DTMDisplaydate} to just \cs{DTMdisplaydate}. As with +%\cs{DTMdisplaydate} the style needs to ensure that any fragile +%content is protected in the event that \cs{DTMDisplaydate} is used +%in an expandable context. (Note that for this reason, I~don't +%recommend the use of the commands provided by the \sty{mfirstuc} +%package as they're not expandable.) +% +%The current date is displayed using +%\begin{definition}[\DescribeMacro\today] +%\cs{today} +%\end{definition} +%This uses \cs{DTMdisplaydate} to format the date so it will match +%the currently selected date style. There's also a first letter +%upper case version that uses \cs{DTMDisplaydate}: +%\begin{definition}[\DescribeMacro\Today] +%\cs{Today} +%\end{definition} +% +%\begin{important} +%If you use \sty{babel} or \sty{polyglossia} you must make sure +%you have the relevant \styfmt{datetime2} language modules installed. +%(See \sectionref{sec:lang}.) You also need to make sure that +%\styfmt{datetime2} is loaded \emph{after} +%\sty{babel}\slash\sty{polyglossia} otherwise \cs{today} will be +%redefined so that it no longer uses \cs{DTMdisplaydate}. +%\end{important} +% +%As mentioned above, some styles allow the day of the week to be +%displayed. This requires the \sty{datetime2-calc} package which will +%automatically be loaded if you set \pkgopt{showdow} in the +%\styfmt{datetime2} package option list or if you set +%\pkgopt{showdow} in \ics{DTMsetup} \emph{in the preamble}. The +%package option \pkgopt{calc} will also load \sty{datetime2-calc} or +%you can load it explicitly using \cs{usepackage} after +%\styfmt{datetime2} has been loaded. (You may use \pkgopt[true]{showdow} in +%the \env{document} environment if the \styfmt{datetime2-calc} +%package has been loaded in the preamble either explicitly or through +%the \pkgopt{calc} option.) +% +%When \sty{datetime2-calc} is loaded, it computes the current day of +%the week (using commands provided by the \sty{pgfcalendar} package) +%which can then be used by \cs{today} or \cs{Today}. If +%\sty{datetime2-calc} isn't loaded then neither \cs{today} nor +%\cs{Today} will display the day of the week, regardless of the +%current style. +% +%If you would like a more convenient syntax and don't care about +%expansion, there is also a~robust \emph{non-expandable} command that +%can be used to display a~particular date: +%\begin{definition}[\DescribeMacro\DTMdate] +%\cs{DTMdate}\marg{date} +%\end{definition} +%As before there's also a capitalised version: +%\begin{definition}[\DescribeMacro\DTMDate] +%\cs{DTMDate}\marg{date} +%\end{definition} +%In these cases the date should be provided as +%\meta{YYYY}\texttt{-}\meta{MM}\texttt{-}\meta{DD} in the argument +%\meta{date}. For example: +%\begin{verbatim} +%\DTMdate{2015-03-23} +%\end{verbatim} +% +%Note that hyphens must always be used, regardless of +%the separator options. Take care that the category code of the +%hyphen hasn't changed when you use this syntax. +% +%\begin{important} +%The year \meta{YYYY} can't be negative\footnotemark\ in \cs{DTMdate} or +%\cs{DTMDate}. Use \cs{DTMdisplaydate} or +%\cs{DTMDisplaydate} instead. +%\end{important}\footnotetext{Well, actually it can if you put it in braces +%and don't use \sty{datetime2-calc}.} +% +%These commands internally use \cs{DTMdisplaydate} and +%\cs{DTMDisplaydate}, respectively. If the \sty{datetime2-calc} +%package has been loaded, the day of the week will be computed, +%otherwise the day of the week will be set to \texttt{-1}. Another +%benefit of the \sty{datetime2-calc} package is that it allows +%additional formats permitted by the \sty{pgfcalendar} package: +%\begin{itemize} +%\item \meta{YYYY}\texttt{-}\meta{MM}\texttt{-last} (the last day of +%the given month). +% +%\item +%\meta{YYYY}\texttt{-}\meta{MM}\texttt{-}\meta{DD}\texttt{+-}\meta{n} +%(\meta{n} days before the given date). +% +%\item +%\meta{YYYY}\texttt{-}\meta{MM}\texttt{-}\meta{DD}\texttt{+}\meta{n} +%(\meta{n} days after the given date). +% +%\item \meta{YYYY}\texttt{-}\meta{MM}\texttt{-last+-}\meta{n} +%(\meta{n} days before the last day of +%the given month). +% +%\item \meta{YYYY}\texttt{-}\meta{MM}\texttt{-last+}\meta{n} +%(\meta{n} days after the last day of +%the given month). +% +%\end{itemize} +%See the \sty{pgfcalendar} package for further details. +% +%If you want to be able to use a date in an expandable context that +%can perform these calculations, consider first saving the date using +%one of the commands described in \sectionref{sec:store} and then use +%one of the expandable commands such as \cs{DTMuse} to display the +%date. +% +%An error or unexpected results may occur if you try using one of +%these extended formats without loading the \sty{datetime2-calc} +%package. An example that only works with \sty{datetime2-calc}: +%\begin{verbatim} +%\DTMdate{2015-03-last} +%\end{verbatim} +%An example that works with or without \sty{datetime2-calc}: +%\begin{verbatim} +%\DTMdate{2015-03-31} +%\end{verbatim} +%In this second case, you'll only notice a difference in the output +%if the style should show the day of the week. +% +%The style of the date is the same as for \cs{DTMdisplaydate} and +%\cs{DTMDisplaydate} (which \cs{DTMdate} and \cs{DTMDate} internally +%use, as mentioned above). +% +%A time can be displayed using +%\begin{definition}[\DescribeMacro\DTMdisplaytime] +%\cs{DTMdisplaytime}\marg{hour}\marg{minute}\marg{sec} +%\end{definition} +%where the arguments are all numerical (using 24 hours). The +%\termdef{time style} currently in effect determines how the time is formatted. +%The command is designed to be used in an expandable context so the +%styles should take care to protect any fragile commands. +% +%Note that this command doesn't display the time zone. To display the +%time zone, you need to use +%\begin{definition}[\DescribeMacro\DTMdisplayzone] +%\cs{DTMdisplayzone}\marg{TZh}\marg{TZm} +%\end{definition} +%where \meta{TZh} is the hour offset and \meta{TZm} is the minute +%offset. The display is governed by the \termdef{zone style}. +%Again, the style should protect any fragile commands in case this is +%used in an expandable context. +% +%The current time (as set at the start of the document build) +%can be displayed using +%\begin{definition}[\DescribeMacro\DTMcurrenttime] +%\cs{DTMcurrenttime} +%\end{definition} +%This internally just uses \cs{DTMdisplaytime} and so is designed for +%use in an expandable context. +% +%The current zone can be displayed using +%\begin{definition}[\DescribeMacro\DTMcurrentzone] +%\cs{DTMcurrentzone} +%\end{definition} +%This internally just uses \cs{DTMdisplayzone} and so is designed for +%use in an expandable context. +% +%\begin{important} +%If the PDF\TeX\ primitive \ics{pdfcreationdate} is defined, the +%current time information is obtained from that, which includes the +%seconds and time zone. Lua\TeX\ also defines this command but +%\XeTeX\ doesn't, and in that case the only way to determine the +%current time is from \TeX's \ics{time} primitive which only contains +%the number of minutes since midnight, which means that the seconds +%and time zone are unavailable. Therefore if \XeTeX\ is used, the +%\pkgopt{showseconds} and \pkgopt{showzone} options are automatically +%switched off. +%\end{important} +% +%There is also a~non-expandable robust command to display the time: +%\begin{definition}[\DescribeMacro\DTMtime] +%\cs{DTMtime}\marg{tm} +%\end{definition} +%where \meta{tm} must be in the 24 hour format +%\meta{hh}\texttt{:}\meta{mm}\texttt{:}\meta{ss} +%(colon-separated numerical arguments). Take care if you use \sty{babel} +%with a~language setting that makes the colon character active. You +%will have to switch off the shorthands in order to use this command +%correctly. +% +%The full date, time and zone (if available) can be displayed using +%\begin{definition}[\DescribeMacro\DTMdisplay] +%\cs{DTMdisplay}\marg{year}\marg{month}\marg{day}\marg{day of week}\marg{hh}\marg{mm}\marg{ss}\marg{TZh}\marg{TZm} +%\end{definition} +%The arguments are all numerical. The way the information is +%displayed in the document is governed by the \termdef{full style} +%(or \termdef{date-time style}). +%Typically the full style will redefine this command to use +%\cs{DTMdisplaydate}, \cs{DTMdisplaytime} and (optionally) +%\cs{DTMdisplayzone}. The \pkgopt{showzone} setting may govern whether +%or not to display the time zone (although a~style may ignore this +%setting). The separators between the date and time and between the time +%and zone are governed by the style. +% +%There is also an analogous version if capitalisation is required: +%\begin{definition}[\DescribeMacro\DTMDisplay] +%\cs{DTMDisplay}\marg{year}\marg{month}\marg{day}\marg{day of week}\marg{hh}\marg{mm}\marg{ss}\marg{TZh}\marg{TZm} +%\end{definition} +%Some styles may simply make this equivalent to \cs{DTMdisplay}. +%Other styles may use a~similar format to \cs{DTMdisplay} but replace +%\cs{DTMdisplaydate} with \cs{DTMDisplaydate}. +% +%The full current date, time and (optionally) zone can be displayed +%using: +%\begin{definition}[\DescribeMacro\DTMnow] +%\cs{DTMnow} +%\end{definition} +%which uses \cs{DTMdisplay} or +%\begin{definition}[\DescribeMacro\DTMNow] +%\cs{DTMNow} +%\end{definition} +%which uses \cs{DTMDisplay}. +% +%\chapter{Storing and Using Dates and Times} +%\label{sec:store} +% +%Date, time and zone information can be saved for later use. Note +%that the information is always saved numerically. The style is only +%applied when the information is later used. The commands that save +%the information are robust and not expandable. The commands that use the +%data are typically expandable although there may be some exceptions. +%Take care that the colon (\texttt{:}) and hyphen (\texttt{-}) +%characters haven't had their normal category code changed. (For +%example, through \sty{babel}'s shortcuts.) In the commands below, +%the \meta{name} (no active characters) is a name that uniquely +%identifies the information. +% +%Dates are saved using +%\begin{definition}[\DescribeMacro\DTMsavedate] +%\cs{DTMsavedate}\marg{name}\marg{date} +%\end{definition} +%where \meta{date} is in the same format as for \cs{DTMdate}. +%As with \cs{DTMdate} (and \cs{DTMDate}) the format can be extended +%with the \sty{datetime2-calc} package. If you want to access the day +%of week, you must make sure that \sty{datetime2-calc} has been +%loaded \emph{before you save the date}. (Remember that the \pkgopt{calc} +%and \pkgopt{showdow} package options will automatically load +%\sty{datetime2-calc}.) If \sty{datetime2-calc} has been loaded, the +%day of week number will be calculated and saved. Whether or not it +%is displayed in the document when the date is later used depends on +%the settings when the date is displayed not when it's saved. +% +%This command will override any previously defined date saved with +%this \meta{name}. If a time or zone hasn't been defined with this +%\meta{name}, the time and zone elements will all be set to 0 +%otherwise they will remain unchanged. +% +%Note that you can't have a negative year in \meta{date}. There's an +%alternative command you can use instead that doesn't try parsing +%\meta{date}: +%\begin{definition}[\DescribeMacro\DTMsavenoparsedate] +%\cs{DTMsavenoparsedate}\marg{name}\marg{YYYY}\marg{MM}\marg{DD}\marg{dow} +%\end{definition} +%The day of week \meta{dow} may be \texttt{-1} if unknown.

If a date or +%zone hasn't been defined with this \meta{name}, the date and zone +%elements will all be set to 0 (or \texttt{-1} for the day of week) otherwise they will remain unchanged. +% +%Times and zone are saved using +%\begin{definition}[\DescribeMacro\DTMsavetimezn] +%\cs{DTMsavetimezn}\marg{name}\marg{time and zone} +%\end{definition} +%where the \meta{time and zone} is in the form +%\begin{display} +%\meta{hh}:\meta{mm}:\meta{ss} \meta{TZh}:\meta{TZm} +%\end{display} +%(Note the space between the seconds and the hour offset.) +% +%This command will override any previously defined time and zone +%saved with this \meta{name}. If a date hasn't been defined with this +%\meta{name}, the year, month and day will be set to zero and the day +%of the week to \texttt{-1} otherwise they will remain unchanged. +% +%All date, time and zone information can be saved at the same time +%using: +%\begin{definition}[\DescribeMacro\DTMsavetimestamp] +%\cs{DTMsavetimestamp}\marg{data} +%\end{definition} +%where \meta{data} is in the format: +%\begin{display} +%\meta{YYYY}-\meta{MM}-\meta{DD}T\meta{hh}:\meta{mm}:\meta{ss}\meta{zone} +%\end{display} +%The \meta{zone} may either be \texttt{Z} or in the form +%\meta{TZh}\texttt{:}\meta{TZm} (for example, \texttt{-03:00} +%or \texttt{-3:0}). This will override any date, time or zone data +%previously saved with this \meta{name}. +% +%The current date and time can be saved using: +%\begin{definition}[\DescribeMacro\DTMsavenow] +%\cs{DTMsavenow}\marg{name} +%\end{definition} +% +%There is also a command that can be used to save the modification +%date of a file, but it's not available for some \TeX\ engines: +%\begin{definition}[\DescribeMacro\DTMsavefilemoddate] +%\cs{DTMsavefilemoddate}\marg{name}\marg{file name} +%\end{definition} +%where \meta{file name} is the name of the file (remember to use +%forward slashes \verb|/| for the directory divider). If you build +%your document using PDF\LaTeX, this command will use the PDF\TeX\ +%primitive \cs{pdffilemoddate}. If you use Lua\TeX\ this command will +%attempt to use \texttt{os.date} but it uses \texttt{\%z} for the +%time zone, which may not work on some operating systems. If you use +%\XeLaTeX\ this command will generate a warning and will assume a +%date of 0000-00-00T00:00:00Z. +% +%The above commands are all localised to the current scope.

You can use +%\begin{verbatim} +%\DTMsetstyle{foo} +%\end{verbatim} +%but this will now only be equivalent to +%\begin{verbatim} +%\DTMsetdatestyle{foo}\DTMsettimestyle{foo} +%\end{verbatim} +%and while \cs{DTMdisplay} and \cs{DTMDisplay} will typically use these date +%and time settings, the way that the date, time and zone are arranged +%will be governed by the full style setting that was already in +%effect before the date and time style changed. +% +%The style changes are all local and so are affected by the current +%scope. +% +%\section{Predefined Styles} +%\label{sec:predefinedstyles} +% +%The base \styfmt{datetime2} package provides a number of predefined +%numerical styles. \sectionref{sec:predefinedfull} lists the full styles, +%which can be used with \cs{DTMsetstyle}, \cs{DTMsetdatestyle}, +%\cs{DTMsettimestyle} and \cs{DTMsetzonestyle}. +%\sectionref{sec:predefinedtime} lists the predefined (partial) times +%styles, which can be used with \cs{DTMsettimestyle} and +%\cs{DTMsetstyle}. +% +%\subsection{Full Styles} +%\label{sec:predefinedfull} +% +%The following are predefined full styles that are provided by the +%base \styfmt{datetime2} package. Additional styles are available +%through the language modules (see \sectionref{sec:lang}). +% +%\begin{description} +%\item[\style{default}] The \style{default} style displays the date in the form +%\begin{display} +%\meta{YYYY}\meta{YMsep}\meta{MM}\meta{MDsep}\meta{DD} +%\end{display} +%where the month \meta{MM} and day of the month \meta{DD} numbers are +%formatted as two digits. The separators \meta{YMsep} and +%\meta{MDsep} default to a hyphen but can be changed using the +%options \pkgopt{yearmonthsep}, \pkgopt{monthdaysep} or +%\pkgopt{datesep} (either through the package options or using +%\ics{DTMsetup}). +% +%The time is displayed in the form: +%\begin{display} +%\meta{hh}\meta{HMsep}\meta{mm}\meta{MSsep}\meta{ss} +%\end{display} +%where the hour, month and seconds are formatted as two digits. The +%final \meta{MSsep}\meta{ss} is omitted if the option +%\pkgopt{showseconds} has been set to \texttt{false}. The separators +%\meta{HMsep} and \meta{MSsep} default to a~colon (\texttt{:}) but +%these may be changed using the options \pkgopt{hourminsep}, +%\pkgopt{minsecsep} or \pkgopt{datetimesep}. +% +%The zone is displayed in form +%\begin{display} +%\meta{TZh}\meta{HMsep}\meta{TZm} +%\end{display} +%or just \texttt{Z} if the option \pkgopt{showisoZ} is set to +%\texttt{true} and both \meta{TZh} and \meta{TZm} are zero. +%The separator \meta{HMsep} is the same as used for the time format. +%The final \meta{HMsep}\meta{TZm} is omitted if the option +%\pkgopt{showzoneminutes} is set to \texttt{false}. The hour offset +%\meta{TZh} is formatted as two digits proceeded by either \texttt{+} +%or \texttt{-} and the minute offset is formatted as two digits. +%Note that since one of the main purposes of this package is to +%provide expandable date commands that can be used to write +%information to external files, no attempt is made to convert the +%hyphen \texttt{-} (for negative offsets) into a minus sign. If you +%want it rendered correctly in your document, consider placing the +%time zone command in math mode and adjust the separators as +%necessary. +% +%The full style is in the form +%\begin{display} +%\meta{date}\meta{DTsep}\meta{time}\meta{TZsep}\meta{zone} +%\end{display} +%The \meta{date}\meta{DTsep} part is omitted if the option +%\pkgopt{showdate} is set to \texttt{false}, and +%the \meta{TZsep}\meta{zone} part is omitted if the option +%\pkgopt{showzone} is set to \texttt{false}. The separator between +%the date and time \meta{DTsep} defaults to \cs{space} but may be +%changed using the \pkgopt{datetimesep} option. The separator between +%the time and zone \meta{TZsep} defaults to nothing but may be +%changed using the \pkgopt{timezonesep} option. +% +%\item[\style{iso}] The \style{iso} style is like the \style{default} +%style but the separators can't be changed. The separators used in +%the date format are fixed as hyphens and the separators used in the +%time and zone formats are fixed as colons. In the full format, the separator between the +%date and time is fixed as \texttt{T} and there's no separator between the +%time and zone. The only options that can change the \style{iso} +%style are \pkgopt{showseconds}, \pkgopt{showdate}, \pkgopt{showzone}, +%\pkgopt{showzoneminutes} and \pkgopt{showisoZ}. +% +%\item[\style{yyyymd}] This is like the \style{default} style +%except that the month and date aren't forced into a two-digit +%format. +% +%\item[\style{ddmmyyyy}] This is like the \style{default} style +%except that the date is formatted in the reverse order +%\begin{display} +%\meta{DD}\meta{MDsep}\meta{MM}\meta{YMsep}\meta{YYYY} +%\end{display} +%The day and month are displayed as two-digits and the separators are +%as for the \style{default} style. The options that modify the +%\style{default} style similarly modify this style. +% +%\item[\style{dmyyyy}] This is like the \style{ddmmyyyy} style except +%that it doesn't force the day and month into a~two-digit format. +%The options that modify the +%\style{default} style similarly modify this style. +% +%\item[\style{dmyy}] This is like the \style{dmyy} style except +%that it only displays the final two digits of the year. +%The options that modify the +%\style{default} style similarly modify this style. +% +%\item[\style{mmddyyyy}] This is like the \style{ddmmyyyy} style +%except the day and month numbers are reversed. The separator between +%the month and day is still given by the \pkgopt{monthdaysep} or +%\pkgopt{datesep} options. The separator between the day and year is given by +%the \pkgopt{dayyearsep} or \pkgopt{datesep} options. +% +%\item[\style{mdyyyy}] This is like the \style{mmddyyyy} style except +%that it doesn't force the day and month into a~two-digit format. +% +%\item[\style{mdyy}] This is like the \style{mdyyyy} style except +%that the year only has the final two digits displayed. +% +%\item[\style{pdf}] This formats the date, time and zone so that the +%full style is in the form required by the date settings in +%\ics{pdfinfo}. The date format is +%\begin{display} +%D:\meta{YYYY}\meta{MM}\meta{DD} +%\end{display} +%where the month and day numbers are displayed as two digits. +% +%The time format is +%\begin{display} +%\meta{hh}\meta{mm}\meta{ss} +%\end{display} +%where the numbers are displayed as two digits. +% +%The zone format is +%\begin{display} +%\meta{hh}'\meta{mm}' +%\end{display} +%or Z for zero time offset if the option \pkgopt{showisoZ} is +%used. (The \pkgopt{showisoZ} option is the only option that modifies +%the \style{pdf} style.) The hour and minutes are displayed as two +%digits where the hour has the sign present (either \texttt{+} or +%\texttt{-}). +% +%The full style is a concatenation of the date, time and zone. +%\begin{display} +%D:\meta{YYYY}\meta{MM}\meta{DD}\meta{hh}\meta{mm}\meta{ss}\meta{hh}'\meta{mm}' +%\end{display} +% +%\end{description} +% +%\subsection{Time Styles} +%\label{sec:predefinedtime} +% +%There's only one predefined time (partial) style provided +%by the base \styfmt{datetime2} package. This style can be used to +%override the time format part of full styles. For example, to use +%the \style{default} full style with the \sty{hmmss} time style: +%\begin{verbatim} +%\DTMsetstyle{default}\DTMsettimestyle{hmmss} +%\end{verbatim} +% +%\begin{description} +%\item[\style{hmmss}] The \style{hmmss} style is like the time style +%provided by the full \style{default} style except that the hour +%isn't forced into two digits. +% +%\end{description} +% +%\subsection{Zone Styles} +%\label{sec:predefinedzone} +% +%The following are predefined zone (partial) styles that are provided +%by the base \styfmt{datetime2} package. These styles can be used to +%override the zone format part of full styles. For example, to use +%the \style{default} full style with the \style{map} zone style: +%\begin{verbatim} +%\DTMsetstyle{default}\DTMsetzonestyle{map} +%\end{verbatim} +% +%\begin{description} +%\item[\style{map}] The \style{map} style uses +%\cs{DTMusezonemapordefault} to display the mapping, if one exists, +%or use the default style, if a mapping doesn't exist. For example: +%\begin{verbatim} +%\DTMNatoZoneMaps +%\DTMsetzonestyle{map} +%\end{verbatim} +%This first defines the NATO mappings and then switches to the +%\style{map} style. +% +%\item[\style{hhmm}] The \style{hhmm} style displays the time zone in +%the form +%\begin{display} +%\meta{TZh}\meta{HMsep}\meta{TZm} +%\end{display} +%where \meta{HMsep} is given by the \pkgopt{hourminsep} option. +%This style honours the \pkgopt{showzoneminutes} option +%but ignores the \pkgopt{showisoZ} option. The hour is always +%prefixed by the sign. +% +%\end{description} +% +%\section{Defining New Styles} +%\label{sec:newstyle} +% +%A new \term{date style} can be defined using: +%\begin{definition}[\DescribeMacro\DTMnewdatestyle] +%\cs{DTMnewdatestyle}\marg{name}\marg{definition} +%\end{definition} +%This defines a \term{partial style} that should only modify +%\cs{DTMdisplaydate} and \cs{DTMDisplaydate}.

This command is expandable. +% +%\begin{definition}[\DescribeMacro\DTMcentury] +%\cs{DTMcentury}\marg{year} +%\end{definition} +%This converts \meta{year} to the century. If \meta{year} is negative it does: +%\begin{display} +%\texttt{-\cs{DTMcentury}\{-\meta{year}\}} +%\end{display} +%Example: +%\begin{verbatim} +%\DTMcentury{1945} +%\end{verbatim} +%expands to \DTMcentury{1945} (not 19). Note that +%\begin{verbatim} +%\DTMcentury{1900} +%\end{verbatim} +%expands to \DTMcentury{1900}. +% +%\begin{definition}[\DescribeMacro\DTMdivhundred] +%\cs{DTMdivhundred}\marg{number} +%\end{definition} +%This expands to $\lfloor\meta{number}/100\rfloor$ (integer division +%by 100 rounded down). For example: +%\begin{verbatim} +%\DTMdivhundred{1945} +%\end{verbatim} +%expands to \DTMdivhundred{1945} and +%\begin{verbatim} +%\DTMdivhundred{1900} +%\end{verbatim} +%expands to \DTMdivhundred{1900}. +% +%\begin{definition}[\DescribeMacro\DTMtexorpdfstring] +%\cs{DTMtexorpdfstring}\marg{\TeX}\marg{PDF} +%\end{definition} +%If \sty{hyperref} is loaded, this is equivalent to +%\cs{texorpdfstring} otherwise it just does the first argument and +%ignores the second. (The check for \sty{hyperref} is deferred until +%the start of the \env{document} environment, so it doesn't matter if +%\sty{hyperref} is loaded after \styfmt{datetime2}.) This command may +%be used to provide alternative text to use if the date\slash +%time\slash zone is displayed in the PDF bookmarks. +% +%\begin{definition}[\DescribeMacro\DTMsep] +%\cs{DTMsep}\marg{tag} +%\end{definition} +%This accesses the value of the \meta{tag}\texttt{sep} base package +%option. (Not the language module options.) +%For example +%\begin{verbatim} +%\DTMsep{yearmonth} +%\end{verbatim} +%expands to the value supplied by the \pkgopt{yearmonthsep} package option. +% +%\begin{definition}[\DescribeMacro\DTMusezonemap] +%\cs{DTMusezonemap}\marg{TZh}\marg{TZm} +%\end{definition} +%This expands to the time zone abbreviation or \cs{relax} if no +%mapping has been set for the given time zone. +% +%You can define a time zone mapping using +%\begin{definition}[\DescribeMacro\DTMdefzonemap] +%\cs{DTMdefzonemap}\marg{TZh}\marg{TZm}\marg{abbr} +%\end{definition} +%For example +%\begin{verbatim} +%\DTMdefzonemap{00}{00}{GMT} +%\DTMdefzonemap{01}{00}{BST} +%\end{verbatim} +%Note that \styfmt{datetime2} doesn't know anything about daylight +%saving, so this is only really designed for dates and times +%in a~specific location. This overwrites any previous mapping +%for this time zone. +% +%The base \styfmt{datetime2} package provides +%\begin{definition}[\DescribeMacro\DTMNatoZoneMaps] +%\cs{DTMNatoZoneMaps} +%\end{definition} +%This defines the military\slash NATO mappings from A (Alpha time) to +%Z (Zulu time). You can use this command if you want these time zones +%(but remember to set an appropriate time zone style that uses +%the zone mappings). +% +%The language modules may provide mappings that are enabled +%when you switch to that style. For example, the \texttt{en-GB} +%language module provides the \pkgopt{mapzone} option which, if set +%to \texttt{true}, will map +00:00 to GMT and +01:00 to BST. See the +%documentation for the language module for further details. +% +%\begin{definition}[\DescribeMacro\DTMclearmap] +%\cs{DTMclearmap}\marg{TZh}\marg{TZm} +%\end{definition} +%Clears the time zone mapping. The regional time zone styles should +%use +%\begin{definition}[\DescribeMacro\DTMresetzones] +%\cs{DTMresetzones} +%\end{definition} +%before applying any regional mappings. This defaults to nothing +%which means that any mappings previously defined by other styles +%won't be cleared. You can redefine this command if you want to clear +%any mappings that aren't relevant for other regions. +% +%You can test if a~mapping is defined using +%\begin{definition}[\DescribeMacro\DTMhaszonemap] +%\cs{DTMhaszonemap}\marg{TZh}\marg{TZm}\marg{true}\marg{false} +%\end{definition} +%This will do \meta{true} if there is a mapping defined for that time +%zone or \meta{false} otherwise. +% +%\begin{definition}[\DescribeMacro\DTMusezonemapordefault] +%\cs{DTMusezonemapordefault}\marg{TZh}\marg{TZm} +%\end{definition} +%This will use the mapping if its defined otherwise it +%will expand to the format +%\meta{TZh}\meta{HMsep}\meta{TZm} +%where \meta{HMsep}\meta{TZm} is omitted if the option +%\pkgopt{showzoneminutes} is set to \texttt{false}. The separator +%\meta{HMsep} is as given by the \pkgopt{hourminsep} option. (The +%\pkgopt{showisoZ} option isn't used here so UTC+00:00 will be +%displayed as +00:00 or +00 if there's no mapping.) +% +%Here's an example of a simple date style that just displays the year +%and month as two digits but uses the \pkgopt{yearmonthsep} option: +%\begin{verbatim} +%\newdatestyle +% {mmyy}% label +% {% definitions +% \renewcommand*{\DTMdisplaydate}[4]{% +% \DTMtwodigits{##2}\DTMsep{yearmonth}\DTMtwodigits{##1}}% +% \renewcommand*{\DTMDisplaydate}{\DTMdisplaydate}% +% } +%\end{verbatim} +% +%If you want to distribute your new styles, just put the definitions +%in a package and upload it to CTAN. For example (replace +%\texttt{mystylename} with something more appropriate, and also +%change the date in the \cs{ProvidesPackage} line): +%\begin{verbatim} +% \NeedsTeXFormat{LaTeX2e} +% \ProvidesPackage{mystylename}[2014/03/24 v1.0] +% \RequirePackage{datetime2} +% +% % style definitions here +% +% \endinput +%\end{verbatim} +%Save the file as \texttt{mystylename.sty}, add some documentation +%about the style (or styles) provided and read the instructions at +%\url{http://www.ctan.org/upload} and +%\url{http://www.ctan.org/file/help/ctan/CTAN-upload-addendum}. The upload location +%for additions to the \styfmt{datetime2} package (either for +%packages defining new styles or for language modules) should be +%\texttt{/macros\slash latex\slash datetime2-contrib\slash mystylename} (remember to +%replace \texttt{mystylename} as appropriate). +% +%\chapter{Multi-Lingual Support} +%\label{sec:lang} +% +%If you want to use \styfmt{datetime2} with \sty{babel} or +%\sty{polyglossia}, make sure you load +%\sty{babel}\slash\sty{polyglossia} \emph{before} you load +%\styfmt{datetime2} otherwise their \cs{date}\meta{language} will +%overwrite \cs{datetime}'s definition of \cs{today}. +%\emph{Additionally} you need to make sure you install the relevant +%\styfmt{datetime2} language modules. These modules are automatically +%loaded, if required, by \styfmt{datetime2} but only if they are +%already installed. Remember that if you use \XeLaTeX\ you won't have +%the seconds or time zone available for the current date and time. +% +%\begin{important} +%If the required language modules aren't installed or +%\styfmt{datetime2} is loaded before +%\sty{babel}\slash\sty{polyglossia} then \styfmt{datetime2}'s +%definition of \cs{today} will be overridden and may no longer match +%the currently selected date style. +%\end{important} +% +%Each language module defines a textual style (where the month is +%displayed as a word) for that language or region +%which can be used in the argument of \cs{DTMsetstyle}, +%\cs{DTMsetdatestyle}, \cs{DTMsettimestyle} or \cs{DTMsetzonestyle}. +%The language module may also define a numeric style. In the +%ambiguous cases where the language name alone doesn't indicate the +%region (for example, \texttt{english} instead of \texttt{UKenglish} or +%\texttt{USenglish}) the module should use the \style{default} numeric +%style (see \sectionref{sec:predefinedfull}). +% +%The textual style provided by the module will automatically be +%set using \cs{DTMsetstyle} \emph{if the \pkgopt{useregional} +%option is set to \texttt{text}}. By default \pkgopt{useregional} is +%\texttt{false}, unless the language\slash region is passed via the +%\styfmt{datetime2} package option list. (The \pkgopt{useregional} +%option is unaffected if the setting is passed through the document +%class option list.) The numeric style provided by the module will +%automatically be set if the \pkgopt{useregional} option is set to +%\texttt{numeric}. See the descriptions for the \pkgopt{useregional} +%and \pkgopt{style} options in \sectionref{sec:pkgopt}. +% +%\begin{important} +%Be careful not to mix the language\slash region options between the document +%class option list and the \sty{babel}\slash\sty{polyglossia} +%interface. For example: +%\begin{verbatim} +%\documentclass[en-GB]{article} +%\usepackage[canadien,british]{babel} +%\end{verbatim} +%This will prevent the \sty{tracklang} package from picking up the +%\sty{babel} setting and it will only detect the \texttt{en-GB} +%option. Use only the document class options or only the \sty{babel} +%package option list or duplicate \emph{all} the \sty{babel} package options with +%analogous \sty{tracklang} options in the document class. For example +%\begin{verbatim} +%\documentclass[canadien,british]{article} +%\usepackage{babel} +%\end{verbatim} +%or +%\begin{verbatim} +%\documentclass{article} +%\usepackage[canadien,british]{babel} +%\end{verbatim} +%or +%\begin{verbatim} +%\documentclass[fr-CA,en-GB]{article} +%\usepackage[canadien,british]{babel} +%\end{verbatim} +%\end{important} +%Language modules may be used without \sty{babel} or \sty{polyglossia}. +%For example: +%\begin{verbatim} +%\documentclass{article} +%\usepackage[en-GB]{datetime2} +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%If you have more than one language or region you will need to switch +%styles using \cs{DTMsetstyle} etc: +%\begin{verbatim} +%\documentclass{article} +%\usepackage[en-GB,en-CA]{datetime2} +%\begin{document} +%\DTMsetstyle{en-GB}\today. +%\DTMsetstyle{en-CA}\today +%\end{document} +%\end{verbatim} +% +%If you want to change the number separators for the \emph{regional} +%numeric styles, you need to use \cs{DTMlangsetup}. If you want to +%change the number separators for the base \styfmt{datetime2} +%predefined numeric styles (see \sectionref{sec:predefinedstyles}) +%then you need to use \cs{DTMsetup} or the package options. You +%therefore need to use \cs{DTMsetup} for the ambiguous regionless +%language numeric settings since they just use the \style{default} +%style. Check the module documentation to find out if the +%\style{default} style is used. +% +%Examples of use: +%\begin{enumerate} +%\item Language option specified through the document class and +%picked up by \sty{tracklang} (which is loaded by \styfmt{datetime2}). +%This setting is also picked up by \sty{babel} which is loaded before +%\styfmt{datetime2}. +%\begin{verbatim} +%\documentclass[british]{article} +% +%\usepackage{babel} +%\usepackage{datetime2} +% +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%The date is displayed in the default format 2015-03-01. +% +%In this case, the \texttt{en-GB} language module is loaded which +%defines the text style \style{en-GB} and the numeric style +%\style{en-GB-numeric}. Since \pkgopt{useregional} hasn't been set, +%\cs{today} uses \styfmt{datetime2}'s \style{default} numerical format. +%If \sty{babel} was loaded after \styfmt{datetime2}, the +%\sty{babel}'s hook management system would overwrite +%\styfmt{datetime2}'s definition of \cs{today} so that it no longer used +%\ics{DTMdisplaydate}. A similar result is obtained if in the above +%example \sty{babel} is replaced with \sty{polyglossia} (where the +%language is set in the document class option). +% +%You can change the \pkgopt{useregional} setting either through +%\styfmt{datetime2}'s package options or using \ics{DTMsetup} however +%it will only have an effect during the module loading (when the +%value is changed via the package option) and when +%\cs{date}\meta{language} is used. +% +%For example, in the document below, the date is displayed using the +%\style{default} numeric format because \pkgopt{useregional} has been +%changed \emph{after} \sty{babel} uses \cs{datebritish} to set the +%language at the start of the document. +%\begin{verbatim} +%\documentclass[british]{article} +% +%\usepackage{babel} +%\usepackage{datetime2} +% +%\begin{document} +%\DTMsetup{useregional} +%\today +%\end{document} +%\end{verbatim} +%So here \cs{today} again displays the date in the form 2015-03-01. +% +%If the setting is moved to the preamble: +%\begin{verbatim} +%\documentclass[british]{article} +% +%\usepackage{babel} +%\usepackage{datetime2} +% +%\DTMsetup{useregional} +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%then the \pkgopt{useregional} setting is checked at the beginning of +%the document when \sty{babel} uses \cs{datebritish}. So in this case +%\cs{today} will display the date in the form 1st March 2015. +% +%\item Language setting specified through \sty{babel}'s package +%option list: +%\begin{verbatim} +%\documentclass{article} +% +%\usepackage[british]{babel} +%\usepackage{datetime2} +% +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%This has the same result as placing \texttt{british} in the document +%class option list, so the date is again displayed in the default +%format 2015-03-01 but, as in the previous example, the \style{en-GB} +%and \style{en-GB-numeric} styles are both defined if required. +% +%However a problem occurs if \sty{babel} is replaced by +%\sty{polyglossia}: +%\begin{verbatim} +%\documentclass{article} +% +%\usepackage{fontspec} +%\usepackage{polyglossia} +%\setdefaultlanguage[variant=uk]{english} +% +%\usepackage{datetime2} +% +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%In this case \sty{tracklang} is unable to pick up the variant and +%can only detect the root language, so it will load the generic +%\texttt{english} module instead of the \texttt{en-GB} module. This +%means that the \style{en-GB} and \style{en-GB-numeric} styles are no longer +%available. However, since \pkgopt{useregional} is \texttt{false} the +%date is still displayed using the \texttt{default} numeric style +%in the form 2015-03-01. +% +%\item As mentioned above neither \sty{babel} nor \sty{polyglossia} are required in +%order to use the \styfmt{datetime2} language modules. You can simply +%supply the language setting in the package option list: +%\begin{verbatim} +%\documentclass{article} +% +%\usepackage[british]{datetime2} +% +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%This additionally sets \pkgopt[true]{useregional} (since the +%language is in the package option list not the document class option +%list) so the date produced by \cs{today} now uses the \texttt{en-GB} +%date style in the form 1st March 2015. +% +%\item The regional numeric format can be used instead if +%\pkgopt{useregional} is set to \texttt{numeric}: +%\begin{verbatim} +%\documentclass{article} +% +%\usepackage[british,useregional=numeric]{datetime2} +% +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%This now displays the date in the form 1/3/2015. +%\end{enumerate} +% +%Many of the language options have synonyms. In addition to the +%\sty{babel} synonyms (such as \pkgopt{british} or +%\pkgopt{UKenglish}) the \sty{tracklang} package provides options in +%ISO form, such as \pkgopt{en-GB}. Note that the style name provided +%by each language module is independent of the package option used +%to select that style. So regardless of whether you use +%\pkgopt{british}, \pkgopt{UKenglish} or \pkgopt{en-GB}, the text style +%name is \style{en-GB} and the numeric style name is +%\style{en-GB-numeric}. If just \pkgopt{english} is used, the text +%style name is \style{english} but the numeric style is +%\style{default}. +% +%Languages where the region is automatically implied, such +%as \pkgopt{scottish}, provide a text style with the root language +%name (\style{scottish} in this instance) and a numeric style in the +%form \meta{language}\texttt{-numeric} (such as \style{scottish-numeric}). +%Note that \texttt{irish} has regionless styles \texttt{irish} and +%\texttt{irish-numeric} but also has regional styles +%\texttt{ga-IE} and \texttt{ga-IE-numeric} (for the Republic of +%Ireland) and \texttt{ga-GB} and \texttt{ga-GB-numeric} (for Northern +%Ireland). In this case the regionless style has a numeric style +%instead of using the \style{default} style since both +%\texttt{ga-IE-numeric} and \texttt{ga-GB-numeric} are the same so +%there's no ambiguity. The only difference in the three modules +%\texttt{datetime2-irish}, \texttt{datetime2-ga-IE} and +%\texttt{datetime2-ga-GB} is the time zone mappings. +% +%The language modules may provide additional settings that can be +%applied using +%\begin{definition}[\DescribeMacro\DTMlangsetup] +%\cs{DTMlangsetup}\oarg{language list}\marg{options} +%\end{definition} +%where \meta{language list} is a comma-separated list of language +%modules that have been loaded (such as \texttt{en-GB,en-US}) +%and \meta{options} is a \meta{key}=\meta{value} list of options. +%If \meta{language list} is omitted, then the list of all loaded +%language modules is assumed. The modules may also provided +%user commands to further customise the style. These settings should +%all be described in the module's documentation, which should be +%accessible via \texttt{texdoc datetime2-\meta{language}} where +%\meta{language} is the root language name in lower case +%(such as \texttt{english}). +% +%Note that although I~maintain the \styfmt{datetime2} English +%language module, I~don't maintain the other modules. If you have an +%issue with one of the other modules, please contact the module +%maintainer. If there is no maintainer, feel free to volunteer to +%take over the maintenance (\href{http://www.dickimaw-books.com/contact.html}{send me a +%message}). If there's no module for your language +%you can create your own module and upload it to CTAN in the +%\texttt{/macros\slash latex\slash datetime2-contrib\slash +%datetime2-\meta{language}} directory. +% +%You can use the English or Irish modules as a template for a +%language with multiple regions. Just download the English source +%files \texttt{datetime2-english.dtx} and +%\texttt{datetime2-english.ins} or the Irish source files +%\texttt{datetime2-irish.dtx} and \texttt{datetime2-irish.ins} from +%CTAN and make the appropriate modifications. Alternatively you can +%use the Scottish module as a template for a single-region language. +%Just download the Scottish source files \texttt{datetime2-scottish.dtx} and +%\texttt{datetime2-scottish.ins} from CTAN and make the appropriate +%modifications. (Don't forget to provide a README file.) +% +%Each language module should be in a file named +%\texttt{datetime2-\meta{lang}.ldf} where \meta{lang} is the language +%name or \meta{language ISO code}\texttt{-}\meta{country ISO code}. (See the +%\sty{tracklang} documentation for further details of the naming +%scheme.) +% +%\begin{important} +%If you want to provide a language module don't assume all users want +%to use the same input encoding or \sty{babel} shortcuts as you. Use \LaTeX\ +%commands for non-ASCII characters (and remember to use \cs{protect} +%where necessary). +%\end{important} +% +%As an addendum to the above warning, Lua\TeX\ and \XeTeX\ support +%UTF-8 characters without the need to make them active, so +%I~recommend you provide two files: one with the \LaTeX\ commands, +%such as \cs{c}, for (PDF)\LaTeX\ users, and one with UTF-8 characters +%for Lua\LaTeX\ and \XeLaTeX\ users. For example, the \texttt{fr-FR} module +%could start with: +%\begin{verbatim} +%\ProvidesDateTimeModule{fr-FR} +% +%\RequirePackage{ifxetex,ifluatex} +% +%\ifxetex +% \RequireDateTimeModule{french-utf8} +%\else +% \ifluatex +% \RequireDateTimeModule{french-utf8} +% \else +% \RequireDateTimeModule{french-ascii} +% \fi +%\fi +%\end{verbatim} +% +%This helps provide fully expandable dates for Lua\LaTeX\ and +%\XeLaTeX\ users. (See the Scottish or Irish modules.) +% +%\chapter{Package Options} +%\label{sec:pkgopt} +% +%The following package options are provided. Most of these are +%\meta{key}=\meta{value} options, unless stated otherwise. +% +%Settings that govern the predefined numerical styles (not including +%the fixed styles \style{iso} and \style{pdf}): +%\begin{description} +%\item[\pkgopt{yearmonthsep}] This sets the separator between the +%year and month for the big-endian and little-endian styles. +%Default: \texttt{-} (hyphen). +% +%\item[\pkgopt{monthdaysep}] This sets the separator between the +%month and day. +%Default: \texttt{-} (hyphen). +% +%\item[\pkgopt{dayyearsep}] This sets the separator between the +%day and year for the middle-endian styles. +%Default: \texttt{-} (hyphen). +% +%\item[\pkgopt{datesep}] This sets the separators between the day and +%month, the month and year, and the day and year. Example: +%\begin{verbatim} +%\usepackage[datesep=/]{datetime2} +%\end{verbatim} +%This is equivalent to: +%\begin{verbatim} +%\usepackage[yearmonthsep=/,monthdaysep=/,dayyearsep=/]{datetime2} +%\end{verbatim} +% +%\item[\pkgopt{hourminsep}] This sets the separator between the hour +%and minute. (Both for the time and for the zone.) +%Default: \texttt{:} (colon). +% +%\item[\pkgopt{minsecsep}] This sets the separator between the minute +%and seconds. +%Default: \texttt{:} (colon). +% +%\item[\pkgopt{timesep}] This sets the separators between the hour +%and minute and between the minute and seconds. +%Example: +%\begin{verbatim} +%\usepackage[timesep=:]{datetime2} +%\end{verbatim} +%This is equivalent to: +%\begin{verbatim} +%\usepackage[hourminsep=:,minsecsep=:]{datetime2} +%\end{verbatim} +%\end{description} +% +%The following settings are used by the predefined numerical styles when +%displaying the full date, time and zone (excluding the fixed styles \style{iso} +%and \style{pdf}) with commands that use \cs{DTMdisplay} or +%\cs{DTMDisplay}. +%\begin{description} +%\item[\pkgopt{datetimesep}] Sets the separator between the date and +%time. +%Default: \cs{space}. +% +%\item[\pkgopt{timezonesep}] Sets the separator between the time and +%zone. +%Default: empty. +% +%\end{description} +% +%The following settings are used by the predefined styles and may +%also be used by the language modules. +%\begin{description} +%\item[\pkgopt{showseconds}] Boolean key to determine whether or not +%to show the seconds when the time is displayed. The \style{iso} +%style honours this setting but the \style{pdf} style ignores it. +%Default: \texttt{true} unless \XeTeX\ is used. +% +%\item[\pkgopt{showdate}] Boolean key to determine whether or not to +%show the date with commands that use \cs{DTMdisplay} or +%\cs{DTMDisplay}. (Some styles may ignore this.) The \style{iso} +%style honours this setting but the \style{pdf} style ignores it. +%Default: \texttt{true} unless \XeTeX\ is used. +% +%\item[\pkgopt{showzone}] Boolean key to determine whether or not to +%show the time zone with commands that use +%\cs{DTMdisplay} or \cs{DTMDisplay}. (Some styles may ignore this.) The \style{iso} style honours this setting but the +%\style{pdf} style ignores it. +%Default: \texttt{true} unless \XeTeX\ is used. +% +%\item[\pkgopt{showzoneminutes}] Boolean key to determine whether or +%not to show the zone offset minutes. The \style{iso} style honours +%this setting but the \style{pdf} style ignores it. This setting is +%ignored if \pkgopt{showzone} is \texttt{false}. +%Default: \texttt{true}. +% +%\item[\pkgopt{showisoZ}] Boolean key to determine whether or not to +%show UTC+00:00 as \texttt{Z} instead of numerically. This option +%may be ignored by zone styles that use the zone mappings. If you +%want all the time zones in military form, you can use +%\cs{DTMNatoZoneMaps} to set up the time zone abbreviations and then +%use a zone style that uses the mappings. +%Default: \texttt{true}. +% +%\end{description} +% +%General settings: +%\begin{description} +%\item[\pkgopt{useregional}] Allowed values: \texttt{false}, +%\texttt{text} or \texttt{numeric}. You may also use \texttt{num} as +%an abbreviation for \texttt{numeric}. If no value is supplied +%\texttt{text} is assumed. +% +%This key determines whether or not to \emph{use} the loaded regional +%settings and, if the regional setting should be used, it determines +%whether the text style (months as words) or numeric style should be +%used. If you haven't loaded \sty{babel} or \sty{polyglossia}, this +%key only has an effect when used as a package option. If you have +%loaded one of those packages, the change comes into effect at module +%load time and whenever \cs{date}\meta{language} is used (which +%includes at the beginning of the \env{document} environment). If you want +%to switch the style at any other time, you need to use +%\cs{DTMsetstyle} but unless \pkgopt[false]{useregional} the next +%instance of \cs{date}\meta{language} will change the style. +% +%Note that setting this option to \texttt{false} doesn't prevent the modules +%from being loaded. It just prevents them from automatically setting the style +%and prevents \cs{date}\meta{language} from changing the style if you +%are using \sty{babel} or \sty{polyglossia}. +% +%The default value is \texttt{false} unless the language or region is +%passed to the \styfmt{datetime2} package option list. However, using \pkgopt{style} +%will set \pkgopt{useregional} to \texttt{false}. +% +%Examples: +%\begin{verbatim} +%\documentclass[british]{article} +%\usepackage{babel} +%\usepackage{datetime2} +%\end{verbatim} +%In the above \pkgopt{useregional} is \texttt{false}. +% +%\begin{verbatim} +%\documentclass{article} +%\usepackage[british]{datetime2} +%\end{verbatim} +%In the above \pkgopt{useregional} is \texttt{text}. +% +%\begin{verbatim} +%\documentclass{article} +%\usepackage[british,style=iso]{datetime2} +%\end{verbatim} +%In the above \pkgopt{useregional} is \texttt{false}. (The +%\pkgopt{british} option implements \pkgopt[text]{usenumerical} +%but the \pkgopt{style} option then implements +%\pkgopt[false]{usenumerical}.) +% +%\begin{verbatim} +%\documentclass{article} +%\usepackage[style=iso,british]{datetime2} +%\end{verbatim} +%In the above \pkgopt{useregional} is \texttt{text}. (The +%\pkgopt{style} option implements \pkgopt[false]{usenumerical} +%but the \pkgopt{british} option then implements +%\pkgopt[text]{usenumerical}.) +% +%\item[\pkgopt{style}] Sets the current style using \cs{DTMsetstyle} +%when the \styfmt{datetime2} package has finished loading. This also sets +%\pkgopt[false]{useregional} but that setting can be overridden later +%in the option list. +% +%Default value: empty (use the default style or the regional style, +%according to the value of \pkgopt{useregional}). +% +%This key isn't available in \cs{DTMsetup}. Use \cs{DTMsetstyle} instead. +% +%\item[\pkgopt{calc}] Load the \sty{datetime2-calc} package. This +%will allow the day of week to be computed and allow you to use the +%\sty{pgfcalendar} offset style date formats in commands like +%\cs{DTMdate} as well as defining the commands described in +%\sectionref{sec:calc}. This option doesn't take a value. It can't be switched +%off. This option can't be used in \cs{DTMsetkeys}. The default is to +%not load \sty{datetime2-calc}. +% +%\item[\pkgopt{showdow}] This is a boolean key that determines +%whether or not to show the day of week in styles that support this. +%Note that \pkgopt[true]{showdow} will automatically load +%\sty{datetime2-calc} so +%\begin{verbatim} +%\usepackage[showdow]{datetime2} +%\end{verbatim} +%is equivalent to +%\begin{verbatim} +%\usepackage[showdow,calc]{datetime2} +%\end{verbatim} +% +%This option may be used in \cs{DTMsetup}, but if you attempt to +%switch it on in the \env{document} environment you'll get an error +%if the \sty{datetime2-calc} package hasn't been loaded. +%Default: \texttt{false}. +% +%\item[\pkgopt{warn}] This is a boolean key. If true (default) +%\styfmt{datetime2} warnings will be displayed. If false, the warnings +%will be suppressed. +%Default: \texttt{true}. +% +%\end{description} +% +%Any additional option passed to the \styfmt{datetime2} package (not +%through \cs{DTMsetup}) will be considered a \sty{tracklang} option +%and will be passed to \cs{TrackPredefinedDialect}. (See the +%\sty{tracklang} documentation for further details of that command.) +% +%Apart from \pkgopt{calc}, \pkgopt{style} and the regional options, all the above +%options can also be set using: +%\begin{definition}[\DescribeMacro\DTMsetup] +%\cs{DTMsetup}\marg{option list} +%\end{definition} +% +%The language modules may additionally provide options which can be +%set using: +%\begin{definition}[\DescribeMacro\DTMlangsetup] +%\cs{DTMlangsetup}\oarg{module list}\marg{option list} +%\end{definition} +% +%This will set the \meta{option list} for each module listed in +%\meta{module list}. Unknown options will generate a~warning rather +%than an error message. The default value of \meta{module list} is +%the list of all loaded modules. +% +%Example: +%\begin{verbatim} +%\documentclass{article} +%\usepackage[british]{datetime2} +%\DTMlangsetup{mapzone} +%\end{verbatim} +%The module list here is \texttt{english-base},\texttt{en-GB} and +%since the \texttt{english-base} doesn't have a \texttt{mapzone} +%option, this will result in a warning: +%\begin{verbatim} +%Package datetime2 Warning: Region `english-base' has ignored +%(datetime2) the following settings: +%(datetime2) mapzone +%\end{verbatim} +%You can either ignore the warning or use the optional argument to +%exclude the \texttt{english-base} module: +%\begin{verbatim} +%\documentclass{article} +%\usepackage[british]{datetime2} +%\DTMlangsetup[en-GB]{mapzone} +%\end{verbatim} +% +%Note that some modules may have options with the same name as the +%above listed package options, but the keys are defined in different +%families (see \sty{xkeyval} documentation) so you need to take care +%to use \cs{DTMsetup} for package-wide settings and \cs{DTMlangsetup} +%for the module-specific settings. +% +%For example, the \pkgopt{datesep} package option described above is +%used by the predefined numerical styles but regional modules that +%provide their own numerical styles may use a different date +%separator that matches their region so they may also provide a +%\texttt{datesep} option independent of the base \pkgopt{datesep} +%option. +% +%Examples: +%\begin{verbatim} +%\documentclass[british]{article} +%\usepackage[datesep=.]{datetime2} +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%The above displays the date in the form +%{\DTMsetup{datesep=.}\DTMsetdatestyle{default}\today} +%since the default style is in use and \pkgopt{datesep} is used as a +%package option. +% +%\begin{verbatim} +%\documentclass[british]{article} +%\usepackage{datetime2} +%\DTMsetup{datesep=.} +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%The above displays the date in the form +%{\DTMsetup{datesep=.}\DTMsetdatestyle{default}\today} +%since the default style is in use and \pkgopt{datesep} is used in +%\cs{DTMsetup}. +% +%\begin{verbatim} +%\documentclass[british]{article} +%\usepackage{datetime2} +%\DTMlangsetup{datesep=.} +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%The above displays the date in the form +%{\DTMlangsetup[en-GB]{datesep=.}\DTMsetdatestyle{default}\today} +%since the default style is in use but \pkgopt{datesep} is used in +%\cs{DTMlangsetup}, which only influences the \style{en-GB-numeric} +%style, which isn't the current style. +% +%\begin{verbatim} +%\documentclass[british]{article} +%\usepackage[useregional=numeric]{datetime2} +%\DTMlangsetup{datesep=.} +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%The above displays the date in the form +%{\DTMlangsetup[en-GB]{datesep=.}\DTMsetdatestyle{en-GB-numeric}\today} +%since the \style{en-GB-numeric} style is in use and \pkgopt{datesep} +%is used in \cs{DTMlangsetup}. +% +%\begin{verbatim} +%\documentclass[british]{article} +%\usepackage[useregional]{datetime2} +%\DTMlangsetup{datesep=.} +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%The above displays the date in the form +%{\DTMlangsetup[en-GB]{datesep=.}\DTMsetdatestyle{en-GB}\today} +%since the \style{en-GB} style is in use and \pkgopt{datesep} is used +%in \cs{DTMlangsetup}, which only influences the +%\style{en-GB-numeric} style. +% +%\begin{verbatim} +%\documentclass[british]{article} +%\usepackage[useregional=numeric]{datetime2} +%\DTMsetup{datesep=.} +%\begin{document} +%\today +%\end{document} +%\end{verbatim} +%The above displays the date in the form +%{\DTMsetup{datesep=.}\DTMsetdatestyle{en-GB-numeric}\today} +%since the \style{en-GB-numeric} style is in use but \pkgopt{datesep} +%is used in \cs{DTMsetup} which influences the base predefined +%numeric styles not the regional styles. +% +%\chapter{The \styfmt{datetime2-calc} Package} +%\label{sec:calc} +% +%The \sty{datetime2-calc} package can be loaded after \styfmt{datetime2} in the +%usual way: +%\begin{verbatim} +%\usepackage{datetime2} +%\usepackage{datetime2-calc} +%\end{verbatim} +%or using the \pkgopt{calc} package option to \styfmt{datetime2}: +%\begin{verbatim} +%\usepackage[calc]{datetime2} +%\end{verbatim} +%or by using \pkgopt[true]{showdow}: +%\begin{verbatim} +%\usepackage[showdow]{datetime2} +%\end{verbatim} +% +%This package loads the \sty{pgfcalendar} package which provides a +%way of computing the day of week from a given date. Once +%\sty{datetime2-calc} has been loaded, you can enable or disable the +%weekday in dates where the style supports this, but note that not +%all styles support this, even if the \sty{datetime2-calc} package +%has been loaded. +% +%As with the commands in \sectionref{sec:store}, the commands +%described below that save date\slash time information will +%\emph{overwrite} any previously defined date\slash time data with +%the same identifying \meta{name}. However, they may only overwrite +%specific elements of the data (for example, just the year, month, +%day and day of week elements) and leave the other elements +%unchanged. Where the remaining elements are undefined they'll be set to +%zero, except for the day of week element, which will be set to +%\texttt{-1}. +% +%In addition to enabling the weekday calculations, the \sty{datetime2-calc} +%package also provides the following commands: +%\begin{definition}[\DescribeMacro\DTMsavejulianday] +%\cs{DTMsavejulianday}\marg{name}\marg{number} +%\end{definition} +%This uses \cs{pgfcalendarjuliantodate} to obtain the year, month and +%day from the given Julian day number and uses +%\cs{pgfcalendarjuliantoweekday} to obtain the day of week and then +%saves it. The date can later be used with commands such as +%\cs{DTMuse}\marg{name} described in \sectionref{sec:store}. +%Example: +%\begin{verbatim} +%\DTMsavejulianday{mydate}{2457023} +%\end{verbatim} +% +%\begin{definition}[\DescribeMacro\DTMsaveddatetojuliandate] +%\cs{DTMsaveddatetojulianday}\marg{name}\marg{register} +%\end{definition} +%This uses \cs{pgfcalendardatetojulian} to convert a previously saved +%date (identified by \meta{name}) to a Julian day.
