+=head1 DESCRIPTION
+
+The C<Time::HiRes> module implements a Perl interface to the
+C<usleep>, C<nanosleep>, C<ualarm>, C<gettimeofday>, and
+C<setitimer>/C<getitimer> system calls, in other words, high
+resolution time and timers. See the L</EXAMPLES> section below and the
+test scripts for usage; see your system documentation for the
+description of the underlying C<nanosleep> or C<usleep>, C<ualarm>,
+C<gettimeofday>, and C<setitimer>/C<getitimer> calls.
+
+If your system lacks C<gettimeofday()> or an emulation of it you don't
+get C<gettimeofday()> or the one-argument form of C<tv_interval()>.
+If your system lacks all of C<nanosleep()>, C<usleep()>,
+C<select()>, and C<poll>, you don't get C<Time::HiRes::usleep()>,
+C<Time::HiRes::nanosleep()>, or C<Time::HiRes::sleep()>.
+If your system lacks both C<ualarm()> and C<setitimer()> you don't get
+C<Time::HiRes::ualarm()> or C<Time::HiRes::alarm()>.
+
+If you try to import an unimplemented function in the C<use> statement
+it will fail at compile time.
+
+If your subsecond sleeping is implemented with C<nanosleep()> instead
+of C<usleep()>, you can mix subsecond sleeping with signals since
+C<nanosleep()> does not use signals. This, however, is not portable,
+and you should first check for the truth value of
+C<&Time::HiRes::d_nanosleep> to see whether you have nanosleep, and
+then carefully read your C<nanosleep()> C API documentation for any
+peculiarities.
+
+If you are using C<nanosleep> for something else than mixing sleeping
+with signals, give some thought to whether Perl is the tool you should
+be using for work requiring nanosecond accuracies.
+
+Remember that unless you are working on a I<hard realtime> system,
+any clocks and timers will be imprecise, especially so if you are working
+in a pre-emptive multiuser system. Understand the difference between
+I<wallclock time> and process time (in UNIX-like systems the sum of
+I<user> and I<system> times). Any attempt to sleep for X seconds will
+most probably end up sleeping B<more> than that, but don't be surpised
+if you end up sleeping slightly B<less>.
+
+The following functions can be imported from this module.
+No functions are exported by default.
+
+=over 4
+
+=item gettimeofday ()
+
+In array context returns a two-element array with the seconds and
+microseconds since the epoch. In scalar context returns floating
+seconds like C<Time::HiRes::time()> (see below).
+
+=item usleep ( $useconds )
+
+Sleeps for the number of microseconds (millionths of a second)
+specified. Returns the number of microseconds actually slept.
+Can sleep for more than one second, unlike the C<usleep> system call.
+Can also sleep for zero seconds, which often works like a I<thread yield>.
+See also C<Time::HiRes::usleep()>, C<Time::HiRes::sleep()>, and
+C<Time::HiRes::clock_nanosleep()>.
+
+Do not expect usleep() to be exact down to one microsecond.
+
+=item nanosleep ( $nanoseconds )
+
+Sleeps for the number of nanoseconds (1e9ths of a second) specified.
+Returns the number of nanoseconds actually slept (accurate only to
+microseconds, the nearest thousand of them). Can sleep for more than
+one second. Can also sleep for zero seconds, which often works like
+a I<thread yield>. See also C<Time::HiRes::sleep()>,
+C<Time::HiRes::usleep()>, and C<Time::HiRes::clock_nanosleep()>.
+
+Do not expect nanosleep() to be exact down to one nanosecond.
+Getting even accuracy of one thousand nanoseconds is good.
+
+=item ualarm ( $useconds [, $interval_useconds ] )
+
+Issues a C<ualarm> call; the C<$interval_useconds> is optional and
+will be zero if unspecified, resulting in C<alarm>-like behaviour.
+
+Returns the remaining time in the alarm in microseconds, or C<undef>
+if an error occurred.
+
+ualarm(0) will cancel an outstanding ualarm().
+
+Note that the interaction between alarms and sleeps is unspecified.
+
+=item tv_interval
+
+tv_interval ( $ref_to_gettimeofday [, $ref_to_later_gettimeofday] )
+
+Returns the floating seconds between the two times, which should have
+been returned by C<gettimeofday()>. If the second argument is omitted,
+then the current time is used.
+
+=item time ()
+
+Returns a floating seconds since the epoch. This function can be
+imported, resulting in a nice drop-in replacement for the C<time>
+provided with core Perl; see the L</EXAMPLES> below.
+
+B<NOTE 1>: This higher resolution timer can return values either less
+or more than the core C<time()>, depending on whether your platform
+rounds the higher resolution timer values up, down, or to the nearest second
+to get the core C<time()>, but naturally the difference should be never
+more than half a second. See also L</clock_getres>, if available
+in your system.
+
+B<NOTE 2>: Since Sunday, September 9th, 2001 at 01:46:40 AM GMT, when
+the C<time()> seconds since epoch rolled over to 1_000_000_000, the
+default floating point format of Perl and the seconds since epoch have
+conspired to produce an apparent bug: if you print the value of
+C<Time::HiRes::time()> you seem to be getting only five decimals, not
+six as promised (microseconds). Not to worry, the microseconds are
+there (assuming your platform supports such granularity in the first
+place). What is going on is that the default floating point format of
+Perl only outputs 15 digits. In this case that means ten digits
+before the decimal separator and five after. To see the microseconds
+you can use either C<printf>/C<sprintf> with C<"%.6f">, or the
+C<gettimeofday()> function in list context, which will give you the
+seconds and microseconds as two separate values.
+
+=item sleep ( $floating_seconds )
+
+Sleeps for the specified amount of seconds. Returns the number of
+seconds actually slept (a floating point value). This function can
+be imported, resulting in a nice drop-in replacement for the C<sleep>
+provided with perl, see the L</EXAMPLES> below.
+
+Note that the interaction between alarms and sleeps is unspecified.
+
+=item alarm ( $floating_seconds [, $interval_floating_seconds ] )
+
+The C<SIGALRM> signal is sent after the specified number of seconds.
+Implemented using C<setitimer()> if available, C<ualarm()> if not.
+The C<$interval_floating_seconds> argument is optional and will be
+zero if unspecified, resulting in C<alarm()>-like behaviour. This
+function can be imported, resulting in a nice drop-in replacement for
+the C<alarm> provided with perl, see the L</EXAMPLES> below.
+
+Returns the remaining time in the alarm in seconds, or C<undef>
+if an error occurred.
+
+B<NOTE 1>: With some combinations of operating systems and Perl
+releases C<SIGALRM> restarts C<select()>, instead of interrupting it.
+This means that an C<alarm()> followed by a C<select()> may together
+take the sum of the times specified for the the C<alarm()> and the
+C<select()>, not just the time of the C<alarm()>.
+
+Note that the interaction between alarms and sleeps is unspecified.
+
+=item setitimer ( $which, $floating_seconds [, $interval_floating_seconds ] )
+
+Start up an interval timer: after a certain time, a signal ($which) arrives,
+and more signals may keep arriving at certain intervals. To disable
+an "itimer", use C<$floating_seconds> of zero. If the
+C<$interval_floating_seconds> is set to zero (or unspecified), the
+timer is disabled B<after> the next delivered signal.
+
+Use of interval timers may interfere with C<alarm()>, C<sleep()>,
+and C<usleep()>. In standard-speak the "interaction is unspecified",
+which means that I<anything> may happen: it may work, it may not.
+
+In scalar context, the remaining time in the timer is returned.
+
+In list context, both the remaining time and the interval are returned.
+
+There are usually three or four interval timers (signals) available: the
+C<$which> can be C<ITIMER_REAL>, C<ITIMER_VIRTUAL>, C<ITIMER_PROF>, or
+C<ITIMER_REALPROF>. Note that which ones are available depends: true
+UNIX platforms usually have the first three, but only Solaris seems to
+have C<ITIMER_REALPROF> (which is used to profile multithreaded programs).
+Win32 unfortunately does not haveinterval timers.
+
+C<ITIMER_REAL> results in C<alarm()>-like behaviour. Time is counted in
+I<real time>; that is, wallclock time. C<SIGALRM> is delivered when
+the timer expires.
+
+C<ITIMER_VIRTUAL> counts time in (process) I<virtual time>; that is,
+only when the process is running. In multiprocessor/user/CPU systems
+this may be more or less than real or wallclock time. (This time is
+also known as the I<user time>.) C<SIGVTALRM> is delivered when the
+timer expires.
+
+C<ITIMER_PROF> counts time when either the process virtual time or when
+the operating system is running on behalf of the process (such as I/O).
+(This time is also known as the I<system time>.) (The sum of user
+time and system time is known as the I<CPU time>.) C<SIGPROF> is
+delivered when the timer expires. C<SIGPROF> can interrupt system calls.
+
+The semantics of interval timers for multithreaded programs are
+system-specific, and some systems may support additional interval
+timers. For example, it is unspecified which thread gets the signals.
+See your C<setitimer()> documentation.
+
+=item getitimer ( $which )
+
+Return the remaining time in the interval timer specified by C<$which>.
+
+In scalar context, the remaining time is returned.
+
+In list context, both the remaining time and the interval are returned.
+The interval is always what you put in using C<setitimer()>.
+
+=item clock_gettime ( $which )
+
+Return as seconds the current value of the POSIX high resolution timer
+specified by C<$which>. All implementations that support POSIX high
+resolution timers are supposed to support at least the C<$which> value
+of C<CLOCK_REALTIME>, which is supposed to return results close to the
+results of C<gettimeofday>, or the number of seconds since 00:00:00:00
+January 1, 1970 Greenwich Mean Time (GMT). Do not assume that
+CLOCK_REALTIME is zero, it might be one, or something else.
+Another potentially useful (but not available everywhere) value is
+C<CLOCK_MONOTONIC>, which guarantees a monotonically increasing time
+value (unlike time() or gettimeofday(), which can be adjusted).
+See your system documentation for other possibly supported values.
+
+=item clock_getres ( $which )
+
+Return as seconds the resolution of the POSIX high resolution timer
+specified by C<$which>. All implementations that support POSIX high
+resolution timers are supposed to support at least the C<$which> value
+of C<CLOCK_REALTIME>, see L</clock_gettime>.
+
+=item clock_nanosleep ( $which, $nanoseconds, $flags = 0)
+
+Sleeps for the number of nanoseconds (1e9ths of a second) specified.
+Returns the number of nanoseconds actually slept. The $which is the
+"clock id", as with clock_gettime() and clock_getres(). The flags
+default to zero but C<TIMER_ABSTIME> can specified (must be exported
+explicitly) which means that C<$nanoseconds> is not a time interval
+(as is the default) but instead an absolute time. Can sleep for more
+than one second. Can also sleep for zero seconds, which often works
+like a I<thread yield>. See also C<Time::HiRes::sleep()>,
+C<Time::HiRes::usleep()>, and C<Time::HiRes::nanosleep()>.
+
+Do not expect clock_nanosleep() to be exact down to one nanosecond.
+Getting even accuracy of one thousand nanoseconds is good.
+
+=item clock()
+
+Return as seconds the I<process time> (user + system time) spent by
+the process since the first call to clock() (the definition is B<not>
+"since the start of the process", though if you are lucky these times
+may be quite close to each other, depending on the system). What this
+means is that you probably need to store the result of your first call
+to clock(), and subtract that value from the following results of clock().
+
+The time returned also includes the process times of the terminated
+child processes for which wait() has been executed. This value is
+somewhat like the second value returned by the times() of core Perl,
+but not necessarily identical. Note that due to backward
+compatibility limitations the returned value may wrap around at about
+2147 seconds or at about 36 minutes.
+
+=item stat
+
+=item stat FH
+
+=item stat EXPR
+
+As L<perlfunc/stat> but with the access/modify/change file timestamps
+in subsecond resolution, if the operating system and the filesystem
+both support such timestamps. To override the standard stat():
+
+ use Time::HiRes qw(stat);
+
+Test for the value of &Time::HiRes::d_hires_stat to find out whether
+the operating system supports subsecond file timestamps: a value
+larger than zero means yes. There are unfortunately no easy
+ways to find out whether the filesystem supports such timestamps.
+UNIX filesystems often do; NTFS does; FAT doesn't (FAT timestamp
+granularity is B<two> seconds).
+
+A zero return value of &Time::HiRes::d_hires_stat means that
+Time::HiRes::stat is a no-op passthrough for CORE::stat(),
+and therefore the timestamps will stay integers. The same
+thing will happen if the filesystem does not do subsecond timestamps,
+even if the &Time::HiRes::d_hires_stat is non-zero.
+
+In any case do not expect nanosecond resolution, or even a microsecond
+resolution. Also note that the modify/access timestamps might have
+different resolutions, and that they need not be synchronized, e.g.
+if the operations are
+
+ write
+ stat # t1
+ read
+ stat # t2
+
+the access time stamp from t2 need not be greater-than the modify
+time stamp from t1: it may be equal or I<less>.

+=head1 C API
+
+In addition to the perl API described above, a C API is available for
+extension writers. The following C functions are available in the
+modglobal hash:
+
+ name C prototype
+ --------------- ----------------------
+ Time::NVtime double (*)()
+ Time::U2time void (*)(pTHX_ UV ret[2])
+
+Both functions return equivalent information (like C<gettimeofday>)
+but with different representations. The names C<NVtime> and C<U2time>
+were selected mainly because they are operating system independent.
+(C<gettimeofday> is Unix-centric, though some platforms like Win32 and
+VMS have emulations for it.)
+
+Here is an example of using C<NVtime> from C:
+
+ double (*myNVtime)(); /* Returns -1 on failure. */
+ SV **svp = hv_fetch(PL_modglobal, "Time::NVtime", 12, 0);
+ if (!svp) croak("Time::HiRes is required");
+ if (!SvIOK(*svp)) croak("Time::NVtime isn't a function pointer");
+ myNVtime = INT2PTR(double(*)(), SvIV(*svp));
+ printf("The current time is: %f\n", (*myNVtime)());
+
+=head1 DIAGNOSTICS
+
+=head2 useconds or interval more than ...
+
+In ualarm() you tried to use number of microseconds or interval (also
+in microseconds) more than 1_000_000 and setitimer() is not available
+in your system to emulate that case.
+
+=head2 negative time not invented yet
+
+You tried to use a negative time argument.
+
+=head2 internal error: useconds < 0 (unsigned ... signed ...)
+
+Something went horribly wrong-- the number of microseconds that cannot
+become negative just became negative. Maybe your compiler is broken?
+
+=head2 useconds or uinterval equal to or more than 1000000
+
+In some platforms it is not possible to get an alarm with subsecond
+resolution and later than one second.
+
+=head2 unimplemented in this platform
+
+Some calls simply aren't available, real or emulated, on every platform.
+
+=head1 CAVEATS
+
+Notice that the core C<time()> maybe rounding rather than truncating.
+What this means is that the core C<time()> may be reporting the time
+as one second later than C<gettimeofday()> and C<Time::HiRes::time()>.
+
+Adjusting the system clock (either manually or by services like ntp)
+may cause problems, especially for long running programs that assume
+a monotonously increasing time (note that all platforms do not adjust
+time as gracefully as UNIX ntp does). For example in Win32 (and derived
+platforms like Cygwin and MinGW) the Time::HiRes::time() may temporarily
+drift off from the system clock (and the original time()) by up to 0.5
+seconds. Time::HiRes will notice this eventually and recalibrate.
+Note that since Time::HiRes 1.77 the clock_gettime(CLOCK_MONOTONIC)
+might help in this (in case your system supports CLOCK_MONOTONIC).
+
+Some systems have APIs but not implementations: for example QNX and Haiku
+have the interval timer APIs but not the functionality.

+=head1 NAME
+
+Time::Local - efficiently compute time from local and GMT time
+
+=head1 SYNOPSIS
+
+ $time = timelocal($sec,$min,$hour,$mday,$mon,$year);
+ $time = timegm($sec,$min,$hour,$mday,$mon,$year);
+
+=head1 DESCRIPTION
+
+This module provides functions that are the inverse of built-in perl
+functions C<localtime()> and C<gmtime()>. They accept a date as a
+six-element array, and return the corresponding C<time(2)> value in
+seconds since the system epoch (Midnight, January 1, 1970 GMT on Unix,
+for example). This value can be positive or negative, though POSIX
+only requires support for positive values, so dates before the
+system's epoch may not work on all operating systems.
+
+It is worth drawing particular attention to the expected ranges for
+the values provided. The value for the day of the month is the actual
+day (ie 1..31), while the month is the number of months since January
+(0..11). This is consistent with the values returned from
+C<localtime()> and C<gmtime()>.
+
+=head1 FUNCTIONS
+
+=head2 C<timelocal()> and C<timegm()>
+
+This module exports two functions by default, C<timelocal()> and
+C<timegm()>.
+
+The C<timelocal()> and C<timegm()> functions perform range checking on
+the input $sec, $min, $hour, $mday, and $mon values by default.
+
+=head2 C<timelocal_nocheck()> and C<timegm_nocheck()>
+
+If you are working with data you know to be valid, you can speed your
+code up by using the "nocheck" variants, C<timelocal_nocheck()> and
+C<timegm_nocheck()>. These variants must be explicitly imported.
+
+ use Time::Local 'timelocal_nocheck';
+
+ # The 365th day of 1999
+ print scalar localtime timelocal_nocheck 0,0,0,365,0,99;
+
+If you supply data which is not valid (month 27, second 1,000) the
+results will be unpredictable (so don't do that).
+
+=head2 Year Value Interpretation
+
+Strictly speaking, the year should be specified in a form consistent
+with C<localtime()>, i.e. the offset from 1900. In order to make the
+interpretation of the year easier for humans, however, who are more
+accustomed to seeing years as two-digit or four-digit values, the
+following conventions are followed:
+
+=over 4
+
+=item *
+
+Years greater than 999 are interpreted as being the actual year,
+rather than the offset from 1900. Thus, 1964 would indicate the year
+Martin Luther King won the Nobel prize, not the year 3864.
+
+=item *
+
+Years in the range 100..999 are interpreted as offset from 1900, so
+that 112 indicates 2012. This rule also applies to years less than
+zero (but see note below regarding date range).
+
+=item *
+
+Years in the range 0..99 are interpreted as shorthand for years in the
+rolling "current century," defined as 50 years on either side of the
+current year. Thus, today, in 1999, 0 would refer to 2000, and 45 to
+2045, but 55 would refer to 1955. Twenty years from now, 55 would
+instead refer to 2055. This is messy, but matches the way people
+currently think about two digit dates. Whenever possible, use an
+absolute four digit year instead.
+
+=back
+
+The scheme above allows interpretation of a wide range of dates,
+particularly if 4-digit years are used.
+
+=head2 Limits of time_t
+
+The range of dates that can be actually be handled depends on the size
+of C<time_t> (usually a signed integer) on the given
+platform. Currently, this is 32 bits for most systems, yielding an
+approximate range from Dec 1901 to Jan 2038.
+
+Both C<timelocal()> and C<timegm()> croak if given dates outside the
+supported range.
+
+=head2 Ambiguous Local Times (DST)
+
+Because of DST changes, there are many time zones where the same local
+time occurs for two different GMT times on the same day. For example,
+in the "Europe/Paris" time zone, the local time of 2001-10-28 02:30:00
+can represent either 2001-10-28 00:30:00 GMT, B<or> 2001-10-28
+01:30:00 GMT.
+
+When given an ambiguous local time, the timelocal() function should
+always return the epoch for the I<earlier> of the two possible GMT
+times.
+
+=head2 Non-Existent Local Times (DST)
+
+When a DST change causes a locale clock to skip one hour forward,
+there will be an hour's worth of local times that don't exist. Again,
+for the "Europe/Paris" time zone, the local clock jumped from
+2001-03-25 01:59:59 to 2001-03-25 03:00:00.
+
+If the C<timelocal()> function is given a non-existent local time, it
+will simply return an epoch value for the time one hour later.
+
+=head2 Negative Epoch Values
+
+Negative epoch (C<time_t>) values are not officially supported by the
+POSIX standards, so this module's tests do not test them. On some
+systems, they are known not to work. These include MacOS (pre-OSX) and
+Win32.
+
+On systems which do support negative epoch values, this module should
+be able to cope with dates before the start of the epoch, down the
+minimum value of time_t for the system.
+
+=head1 IMPLEMENTATION
+
+These routines are quite efficient and yet are always guaranteed to
+agree with C<localtime()> and C<gmtime()>. We manage this by caching
+the start times of any months we've seen before. If we know the start
+time of the month, we can always calculate any time within the month.
+The start times are calculated using a mathematical formula. Unlike
+other algorithms that do multiple calls to C<gmtime()>.
+
+The C<timelocal()> function is implemented using the same cache. We
+just assume that we're translating a GMT time, and then fudge it when
+we're done for the timezone and daylight savings arguments. Note that
+the timezone is evaluated for each date because countries occasionally
+change their official timezones. Assuming that C<localtime()> corrects
+for these changes, this routine will also be correct.
+
+=head1 BUGS
+
+The whole scheme for interpreting two-digit years can be considered a
+bug.
+

+list. See http://lists.perl.org/ for more details.

+=head1 NAME
+
+Time::Piece - Object Oriented time objects
+
+=head1 SYNOPSIS
+
+ use Time::Piece;
+
+ my $t = localtime;
+ print "Time is $t\n";
+ print "Year is ", $t->year, "\n";
+
+=head1 DESCRIPTION
+
+This module replaces the standard localtime and gmtime functions with
+implementations that return objects. It does so in a backwards
+compatible manner, so that using localtime/gmtime in the way documented
+in perlfunc will still return what you expect.
+
+The module actually implements most of an interface described by
+Larry Wall on the perl5-porters mailing list here:
+http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2000-01/msg00241.html
+
+=head1 USAGE
+
+After importing this module, when you use localtime or gmtime in a scalar
+context, rather than getting an ordinary scalar string representing the
+date and time, you get a Time::Piece object, whose stringification happens
+to produce the same effect as the localtime and gmtime functions. There is
+also a new() constructor provided, which is the same as localtime(), except
+when passed a Time::Piece object, in which case it's a copy constructor. The
+following methods are available on the object:
+
+ $t->sec # also available as $t->second
+ $t->min # also available as $t->minute
+ $t->hour # 24 hour
+ $t->mday # also available as $t->day_of_month
+ $t->mon # 1 = January
+ $t->_mon # 0 = January
+ $t->monname # Feb
+ $t->month # same as $t->monname
+ $t->fullmonth # February
+ $t->year # based at 0 (year 0 AD is, of course 1 BC)
+ $t->_year # year minus 1900
+ $t->yy # 2 digit year
+ $t->wday # 1 = Sunday
+ $t->_wday # 0 = Sunday
+ $t->day_of_week # 0 = Sunday
+ $t->wdayname # Tue
+ $t->day # same as wdayname
+ $t->fullday # Tuesday
+ $t->yday # also available as $t->day_of_year, 0 = Jan 01
+ $t->isdst # also available as $t->daylight_savings
+
+ $t->hms # 12:34:56
+ $t->hms(".") # 12.34.56
+ $t->time # same as $t->hms
+
+ $t->ymd # 2000-02-29
+ $t->date # same as $t->ymd
+ $t->mdy # 02-29-2000
+ $t->mdy("/") # 02/29/2000
+ $t->dmy # 29-02-2000
+ $t->dmy(".") # 29.02.2000
+ $t->datetime # 2000-02-29T12:34:56 (ISO 8601)
+ $t->cdate # Tue Feb 29 12:34:56 2000
+ "$t" # same as $t->cdate
+
+ $t->epoch # seconds since the epoch
+ $t->tzoffset # timezone offset in a Time::Seconds object
+
+ $t->julian_day # number of days since Julian period began
+ $t->mjd # modified Julian date (JD-2400000.5 days)
+
+ $t->week # week number (ISO 8601)
+
+ $t->is_leap_year # true if it its
+ $t->month_last_day # 28-31
+
+ $t->time_separator($s) # set the default separator (default ":")
+ $t->date_separator($s) # set the default separator (default "-")
+ $t->day_list(@days) # set the default weekdays
+ $t->mon_list(@days) # set the default months
+
+ $t->strftime(FORMAT) # same as POSIX::strftime (without the overhead
+ # of the full POSIX extension)
+ $t->strftime() # "Tue, 29 Feb 2000 12:34:56 GMT"
+
+ Time::Piece->strptime(STRING, FORMAT)
+ # see strptime man page. Creates a new
+ # Time::Piece object
+
+=head2 Local Locales
+
+Both wdayname (day) and monname (month) allow passing in a list to use
+to index the name of the days against. This can be useful if you need
+to implement some form of localisation without actually installing or
+using locales.
+
+ my @days = qw( Dimanche Lundi Merdi Mercredi Jeudi Vendredi Samedi );
+
+ my $french_day = localtime->day(@days);
+
+These settings can be overriden globally too:
+
+ Time::Piece::day_list(@days);
+
+Or for months:
+
+ Time::Piece::mon_list(@months);
+
+And locally for months:
+
+ print localtime->month(@months);
+
+=head2 Date Calculations
+
+It's possible to use simple addition and subtraction of objects:
+
+ use Time::Seconds;
+
+ my $seconds = $t1 - $t2;
+ $t1 += ONE_DAY; # add 1 day (constant from Time::Seconds)
+
+The following are valid ($t1 and $t2 are Time::Piece objects):
+
+ $t1 - $t2; # returns Time::Seconds object
+ $t1 - 42; # returns Time::Piece object
+ $t1 + 533; # returns Time::Piece object
+
+However adding a Time::Piece object to another Time::Piece object
+will cause a runtime error.
+
+Note that the first of the above returns a Time::Seconds object, so
+while examining the object will print the number of seconds (because
+of the overloading), you can also get the number of minutes, hours,
+days, weeks and years in that delta, using the Time::Seconds API.
+
+In addition to adding seconds, there are two APIs for adding months and
+years:
+
+ $t->add_months(6);
+ $t->add_years(5);
+
+The months and years can be negative for subtractions. Note that there
+is some "strange" behaviour when adding and subtracting months at the
+ends of months. Generally when the resulting month is shorter than the
+starting month then the number of overlap days is added. For example
+subtracting a month from 2008-03-31 will not result in 2008-02-31 as this
+is an impossible date. Instead you will get 2008-03-02. This appears to
+be consistent with other date manipulation tools.
+
+=head2 Date Comparisons
+
+Date comparisons are also possible, using the full suite of "<", ">",
+"<=", ">=", "<=>", "==" and "!=".
+
+=head2 Date Parsing
+
+Time::Piece links to your C library's strptime() function, allowing
+you incredibly flexible date parsing routines. For example:
+
+ my $t = Time::Piece->strptime("Sun 3rd Nov, 1943",
+ "%A %drd %b, %Y");
+
+ print $t->strftime("%a, %d %b %Y");
+
+Outputs:
+
+ Wed, 03 Nov 1943
+
+(see, it's even smart enough to fix my obvious date bug)
+
+For more information see "man strptime", which should be on all unix
+systems.
+
+=head2 YYYY-MM-DDThh:mm:ss
+
+The ISO 8601 standard defines the date format to be YYYY-MM-DD, and
+the time format to be hh:mm:ss (24 hour clock), and if combined, they
+should be concatenated with date first and with a capital 'T' in front
+of the time.
+
+=head2 Week Number
+
+The I<week number> may be an unknown concept to some readers. The ISO
+8601 standard defines that weeks begin on a Monday and week 1 of the
+year is the week that includes both January 4th and the first Thursday
+of the year. In other words, if the first Monday of January is the
+2nd, 3rd, or 4th, the preceding days of the January are part of the
+last week of the preceding year. Week numbers range from 1 to 53.
+
+=head2 Global Overriding
+
+Finally, it's possible to override localtime and gmtime everywhere, by
+including the ':override' tag in the import list:
+
+ use Time::Piece ':override';
+
+=head1 CAVEATS
+
+=head2 Setting $ENV{TZ} in Threads on Win32
+
+Note that when using perl in the default build configuration on Win32
+(specifically, when perl is built with PERL_IMPLICIT_SYS), each perl
+interpreter maintains its own copy of the environment and only the main
+interpreter will update the process environment seen by strftime.
+
+Therefore, if you make changes to $ENV{TZ} from inside a thread other than
+the main thread then those changes will not be seen by strftime if you
+subsequently call that with the %Z formatting code. You must change $ENV{TZ}
+in the main thread to have the desired effect in this case (and you must
+also call _tzset() in the main thread to register the environment change).
+
+Furthermore, remember that this caveat also applies to fork(), which is
+emulated by threads on Win32.
+
+=head2 Use of epoch seconds
+
+This module internally uses the epoch seconds system that is provided via
+the perl C<time()> function and supported by C<gmtime()> and C<localtime()>.
+
+If your perl does not support times larger than C<2^31> seconds then this
+module is likely to fail at processing dates beyond the year 2038. There are
+moves afoot to fix that in perl. Alternatively use 64 bit perl. Or if none
+of those are options, use the L<DateTime> module which has support for years
+well into the future and past.

+Time::Seconds - a simple API to convert seconds to other date values
+
+=head1 SYNOPSIS
+
+ use Time::Piece;
+ use Time::Seconds;
+
+ my $t = localtime;
+ $t += ONE_DAY;
+
+ my $t2 = localtime;
+ my $s = $t - $t2;

+
+=head1 DESCRIPTION
+
+This module is part of the Time::Piece distribution. It allows the user
+to find out the number of minutes, hours, days, weeks or years in a given
+number of seconds. It is returned by Time::Piece when you delta two
+Time::Piece objects.
+
+Time::Seconds also exports the following constants:
+
+ ONE_DAY
+ ONE_WEEK
+ ONE_HOUR
+ ONE_MINUTE
+ ONE_MONTH
+ ONE_YEAR
+ ONE_FINANCIAL_MONTH
+ LEAP_YEAR
+ NON_LEAP_YEAR
+
+Since perl does not (yet?) support constant objects, these constants are in
+seconds only, so you cannot, for example, do this: C<print ONE_WEEK-E<gt>minutes;>
+
+=head1 METHODS
+
+The following methods are available:
+
+ my $val = Time::Seconds->new(SECONDS)
+ $val->seconds;
+ $val->minutes;
+ $val->hours;
+ $val->days;
+ $val->weeks;
+ $val->months;
+ $val->financial_months; # 30 days
+ $val->years;
+
+The methods make the assumption that there are 24 hours in a day, 7 days in
+a week, 365.24225 days in a year and 12 months in a year.

+Time::gmtime - by-name interface to Perl's built-in gmtime() function
+
+=head1 SYNOPSIS
+
+ use Time::gmtime;
+ $gm = gmtime();
+ printf "The day in Greenwich is %s\n",
+ (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $gm->wday() ];
+
+ use Time::gmtime qw(:FIELDS);

+ printf "The day in Greenwich is %s\n",
+ (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $tm_wday ];
+
+ $now = gmctime();
+
+ use Time::gmtime;
+ use File::stat;
+ $date_string = gmctime(stat($file)->mtime);
+
+=head1 DESCRIPTION
+
+This module's default exports override the core gmtime() function,
+replacing it with a version that returns "Time::tm" objects.
+This object has methods that return the similarly named structure field
+name from the C's tm structure from F<time.h>; namely sec, min, hour,
+mday, mon, year, wday, yday, and isdst.
+
+You may also import all the structure fields directly into your namespace
+as regular variables using the :FIELDS import tag. (Note that this
+still overrides your core functions.) Access these fields as variables
+named with a preceding C<tm_> in front their method names. Thus,
+C<$tm_obj-E<gt>mday()> corresponds to $tm_mday if you import the fields.
+
+The gmctime() function provides a way of getting at the
+scalar sense of the original CORE::gmtime() function.
+
+To access this functionality without the core overrides,
+pass the C<use> an empty import list, and then access
+function functions with their full qualified names.
+On the other hand, the built-ins are still available
+via the C<CORE::> pseudo-package.
+
+=head1 NOTE
+
+While this class is currently implemented using the Class::Struct
+module to build a struct-like class, you shouldn't rely upon this.

+
+This module is used internally as a base class by Time::localtime And
