\chapter{Week-Day and Time Using \Package{scrdate} and \Package{scrtime}}
\labelbase{datetime}
There are two packages at \KOMAScript{} to improve and extend the
handling of date\Index{date} and time\Index{time}. So you have not
only the standard commands \Macro{today} and \Macro{date}. Like all
the other packages from \KOMAScript{} bundle these two packages may be used
not only with \KOMAScript{} classes but also with standard and many
other classes.
\section{The Name of the Current Day of Week Using \Package{scrdate}}
\label{sec:sec:datetime.scrdate}
\BeginIndex{Package}{scrdate}
The first problem is the question about the current day of week. The answer
may be given by the package \Package{scrdate}.
\begin{Declaration}
\Macro{todaysname}
\end{Declaration}%
\BeginIndex{Cmd}{todaysname}%
You should know, that you may get the current date with
\Macro{today}\IndexCmd{today} in a language dependend
spelling. \Package{scrdate} offers you the command \Macro{todaysname}. This
results in the name of the current day of week in a language dependend
spelling.
\begin{Example}
At your document you want to show the name of the week-day at which
the \File{dvi}-file was generated using \LaTeX. To do this, you
write:
\begin{lstlisting}
I've done the \LaTeX-run of this document on a \todaysname.
\end{lstlisting}
This will result in e.g.:
\begin{quote}
I've done the \LaTeX-run of this document on a \todaysname.
\end{quote}
\end{Example}
Note that the package isn't able to decline. The known terms are the nominativ
singular that may be used e.g. at the date of a letter. For this the example
above is correct only at some languages.
\begin{Explain}
\textbf{Tip:} The names of the week-days are saved in
capitalization. So the first letter is a capital letter, all the
others are small letters. But at some languages you also need the
names with a first letter in lower case. You may achieve this using
the standard \LaTeX{} command \Macro{MakeLowercase}. You simply have
to write \Macro{MakeLowercase}\PParameter{\Macro{todaysname}}.
\end{Explain}
\EndIndex{Cmd}{todaysname}
\begin{Declaration}
\Macro{nameday}\Parameter{name}
\end{Declaration}%
\BeginIndex{Cmd}{nameday}%
You should know, that you may change the output of \Macro{today} using
\Macro{date}\IndexCmd{date}. In a analogous way you can change the
output of \Macro{todaysname} using \Macro{nameday} into \PName{name}.
\begin{Example}
You're changing the current date into a fix value using
\Macro{date}. You are not interested in the name of the day, but
you want to show, that it is a workday. So you set:
\begin{lstlisting}
\nameday{workday}
\end{lstlisting}
After this the previous example will result in:
\begin{quote}
I've done the \LaTeX-run of this document on a workday.
\end{quote}
\end{Example}
\EndIndex{Cmd}{nameday}
Package \Package{scrdate} knows the languages english (english, american,
USenglish, UKenglish and british), german (german, ngerman and austrian),
french, italian, spanish, croatian, and finnish. If you want to configure it
for other languages, see \File{scrdate.dtx}.
At current implementation it doesn't matter, if you're loading
\Package{scrdate} before or after
\Package{german}\IndexPackage{german},
\Package{ngerman}\IndexPackage{ngerman},
\Package{babel}\IndexPackage{babel} or similar packages. The current
language will be setup at \Macro{begin}\PParameter{document}.
\begin{Explain}
To explain it a little bit more exactly: While you are using a
language selection, which works in a compatible way to
\Package{babel}\IndexPackage{babel} or
\Package{german}\IndexPackage{german}, the correct language will be
used by \Package{scrdate}. If you are using another language
selection you will get english caption names. At \File{scrdate.dtx}
you will find the description of the \Package{scrdate}-commands for
defining the names.
\end{Explain}
\EndIndex{Package}{scrdate}
\section{Getting the Time with Package \Package{scrtime}}
\label{sec:datetime.scrtime}
\BeginIndex{Package}{scrtime}
The second problem is the question about current time. The solution may be
found using package \Package{scrtime}.
\begin{Declaration}%
\Macro{thistime}\OParameter{delimiter}\\
\Macro{thistime*}\OParameter{delimiter}
\end{Declaration}%
\BeginIndex{Cmd}{thistime}\BeginIndex{Cmd}{thistime*}%
\Macro{thistime} results in the current\Index{time}.
The delimiter between the values of hour and minute
can be given in the optional argument.
The default symbol of the delimiter is "\PValue{:}".
\Macro{thistime*} works in the same way as \Macro{thistime}.
The difference between both is that the value of the minute
using \Macro{thistime*} is not preceded with zero when its value
is less than 10, thus using \Macro{thistime} the minute-value
has always two places.
\begin{Example}
The line
\begin{lstlisting}
Your train departs at \thistime .
\end{lstlisting}
results for example in:
\begin{quote}
Your train departs at \thistime .
\end{quote}
or:
\begin{quote}
Your train departs at 23:09.
\end{quote}
\bigskip
In contrast to the prevous example a line like:
\begin{lstlisting}
This day is already \thistime*[\ hours and\ ] minutes old.
\end{lstlisting}
results in:
\begin{quote}
This day is already \thistime*[\ hours and\ ] minutes old.
\end{quote}
or:
\begin{quote}
This day is already 12 hours and 25 minutes old.
\end{quote}
\end{Example}
\EndIndex{Cmd}{thistime}\EndIndex{Cmd}{thistime*}
\begin{Declaration}%
\Macro{settime}\Parameter{Time}
\end{Declaration}%
\BeginIndex{Cmd}{settime}%
\Macro{settime} sets the output \Macro{thistime} and
\Macro{thistime*} on the value of \PName{Time}.
Afterwards the optinal parameter of \Macro{thistime} or
\Macro{thistime*} is ignored, since the result
of \Macro{thistime} or \Macro{thistime*}
was completely determined using \Macro{settime}.%
\EndIndex{Cmd}{settime}
\begin{Declaration}
\Option{12h}\\
\Option{24h}
\end{Declaration}%
\BeginIndex{Option}{12h}\BeginIndex{Option}{24h}%
Using the options \Option{12h} and \Option{24h} one can
select whether the result of \Macro{thistime} and \Macro{thistime*}
is in 12- or in 24-hour format. The default is \Option{24h}.%
The option has no effect on the results of
\Macro{thistime} and \Macro{thistime*} if \Macro{settime}
has been used.%
\EndIndex{Option}{12h}\EndIndex{Option}{24h}
\EndIndex{Package}{scrtime}
