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>. - -=back - -=head1 EXAMPLES - - use Time::HiRes qw(usleep ualarm gettimeofday tv_interval); - - $microseconds = 750_000; - usleep($microseconds); - - # signal alarm in 2.5s & every .1s thereafter - ualarm(2_500_000, 100_000); - # cancel that ualarm - ualarm(0); - - # get seconds and microseconds since the epoch - ($s, $usec) = gettimeofday(); - - # measure elapsed time - # (could also do by subtracting 2 gettimeofday return values) - $t0 = [gettimeofday]; - # do bunch of stuff here - $t1 = [gettimeofday]; - # do more stuff here - $t0_t1 = tv_interval $t0, $t1; - - $elapsed = tv_interval ($t0, [gettimeofday]); - $elapsed = tv_interval ($t0); # equivalent code - - # - # replacements for time, alarm and sleep that know about - # floating seconds - # - use Time::HiRes; - $now_fractions = Time::HiRes::time; - Time::HiRes::sleep (2.5); - Time::HiRes::alarm (10.6666666); - - use Time::HiRes qw ( time alarm sleep ); - $now_fractions = time; - sleep (2.5); - alarm (10.6666666); - - # Arm an interval timer to go off first at 10 seconds and - # after that every 2.5 seconds, in process virtual time - - use Time::HiRes qw ( setitimer ITIMER_VIRTUAL time ); - - $SIG{VTALRM} = sub { print time, "\n" }; - setitimer(ITIMER_VIRTUAL, 10, 2.5); - - use Time::HiRes qw( clock_gettime clock_getres CLOCK_REALTIME ); - # Read the POSIX high resolution timer. - my $high = clock_getres(CLOCK_REALTIME); - # But how accurate we can be, really? - my $reso = clock_getres(CLOCK_REALTIME); - - use Time::HiRes qw( clock_nanosleep TIMER_ABSTIME ); - clock_nanosleep(CLOCK_REALTIME, 1e6); - clock_nanosleep(CLOCK_REALTIME, 2e9, TIMER_ABSTIME); - - use Time::HiRes qw( clock ); - my $clock0 = clock(); - ... # Do something. - my $clock1 = clock(); - my $clockd = $clock1 - $clock0; - - use Time::HiRes qw( stat ); - my ($atime, $mtime, $ctime) = (stat("istics"))[8, 9, 10]; - -=head1 C API - -In addition to the perl API described above, a C API is available for -extension writers.

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. - -=head1 SUPPORT - -Support for this module is provided via the datetime@perl.org email -list. See http://lists.perl.org/ for more details. - -Please submit bugs to the CPAN RT system at -http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Time-Local or via email -at bug-time-local@rt.cpan.org. - -=head1 COPYRIGHT - -Copyright (c) 1997-2003 Graham Barr, 2003-2007 David Rolsky.

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. - -=head1 AUTHOR - -Matt Sergeant, matt@sergeant.org -Jarkko Hietaniemi, jhi@iki.fi (while creating Time::Piece for core perl) - -=head1 License - -This module is free software, you may distribute it under the same terms -as Perl. - -=head1 SEE ALSO - -The excellent Calendar FAQ at http://www.tondering.dk/claus/calendar.html - -=head1 BUGS - -The test harness leaves much to be desired.
