NAME
    Time::Local::Extended - Increase the range of localtime and timelocal

SYNOPSIS
      use Time::Local::Extended qw(:ALL);

      my @localtime   = localtime(2**31);
      my $seconds     = timelocal(0,0,0,1,10,170);
      my $gmt_seconds = timegm(0,0,0,1,10,170);
      my $gmt_time    = gmtime(2**31);
      my $ux_time     = UNIX_TIMESTAMP('2097-07-04 12:34:56');
      my $date        = FROM_UNIXTIME(2**31);

      my $sql = qq(
             SELECT start_time
             FROM   project
             WHERE  id = 1
      );
      my $date_time = $dbh->selectrow_array($sql); # '2097-07-04 12:34:56'
      my $ux_time   = UNIX_TIMESTAMP($date_time);  # 4023794096

      my $date_time = FROM_UNIXTIME(2**31);
      my $sql  = qq(
             UPDATE project
             SET    start_time = ?
             WHERE  id = 1
      );
      $dbh->do($sql, undef, $date_time);

DESCRIPTION
    This module extends the date range of localtime(), gmtime(), timegm()
    and timelocal() to go safely beyond 2038 and before 1970 on any
    operating system.

    It also provides a handful of useful time conversion functions.

PUBLIC FUNCTIONS
    *   timelocal

        Invoked in the same way as Time::Local::timelocal().

    *   localtime

        Invoked in the same way as CORE::localtime().

    *   timegm

        Invoked in the same way as Time::Local::timegm().

    *   gmtime

        Invoked in the same way as CORE::gmtime().

    *   UNIX_TIMESTAMP

        Invoked similarly to the MySQL UNIX_TIMESTAMP() function()

    *   FROM_UNIXTIME

        Invoked similarly to the MySQL FROM_UNIXTIME() function()

LIMITATIONS
    Because of the way timegm() and timelocal() try to Do What You Mean with
    the year, it is impossible to feed it the years 0 through 99 (it thinks
    you mean 2000 - 2099).

    While the code can in theory go out to 2**63, the practical portable
    limit of this code is from 2**52 to -2**52 (the limit of double floating
    point precision) after which precision starts to drop off. This gives
    you a range of about +/- 142 million years.

BUGS
    Doesn't correctly handle British Summer Time 1968-1971
