time::y2038

Time::y2038(3pm)					User Contributed Perl Documentation					  Time::y2038(3pm)

NAME

       Time::y2038 - Versions of Perl's time functions which work beyond 2038

SYNOPSIS

	   use Time::y2038;

	   print scalar gmtime 2**52;  # Sat Dec  6 03:48:16 142715360

DESCRIPTION

       On many computers, Perl's time functions will not work past the year 2038.  This is a design fault in the underlying C libraries Perl uses.
       Time::y2038 provides replacements for those functions which will work accurately +/1 142 million years.

       This only imports the functions into your namespace.  To replace it everywhere, see Time::y2038::Everywhere.

       Replaces the following functions:

       gmtime()

       See "gmtime" in perlfunc for details.

       localtime()

       See "localtime" in perlfunc for details.

       timegm()

	   my $time = timegm($sec, $min, $hour, $month_day, $month, $year);

       The inverse of "gmtime()", takes a date and returns the coorsponding $time (number of seconds since Midnight, January 1st, 1970 GMT).  All
       values are the same as "gmtime()" so $month is 0..11 (January is 0) and the $year is years since 1900 (2008 is 108).

	   # June 4, 1906 03:02:01 GMT
	   my $time = timegm(1, 2, 3, 4, 5, 6);

       timegm() can take two additional arguments which are always ignored.  This lets you feed the results from gmtime() back into timegm()
       without having to strip the arguments off.

       The following is always true:

	   timegm(gmtime($time)) == $time;

       timelocal()

	   my $time = timelocal($sec, $min, $hour, $mday, $month, $year);
	   my $time = timelocal($sec, $min, $hour, $mday, $month, $year, $wday, $yday, $isdst);

       Like "timegm()", but interprets the date in the current time zone.

       "timelocal()" will normally figure out if daylight savings time is in effect, but if $isdst is given this will override that check.  This
       is mostly useful to resolve ambiguous times around "fall back" when the hour between 1am and 2am occurs twice.

	   # Sun Nov  4 00:59:59 2007
	   print timelocal(59, 59, 0, 4, 10, 107);  # 1194163199

	   # Sun Nov  4 01:00:00 2007 DST, one second later
	   print timelocal(0, 0, 1, 4, 10, 107, undef, undef, 1);  # 1194163200

	   # Sun Nov  4 01:00:00 2007 no DST, one hour later
	   print timelocal(0, 0, 1, 4, 10, 107, undef, undef, 0);  # 1194166800

       $wday and $yday are ignored.  They are only there for compatibility with the return value of "localtime()".

LIMITATIONS

       The safe range of times is +/ 2**52 (about 142 million years).

       Although the underlying time library can handle times from -2**63 to 2**63-1 (about +/- 292 billion years) Perl uses floating point numbers
       internally and so accuracy degrates after 2**52.
