NAME

Time::Epoch - Convert between Perl epoch and other epochs

SYNOPSIS

  #!/usr/bin/perl -wl
  use Time::Epoch;
  my $perlsec  = 966770660;  # Sun Aug 20 07:24:21 2000 -0400 on Mac OS
  my $epochsec = perl2epoch($perlsec, 'macos', '-0400');
  my $perlsec2 = epoch2perl($epochsec, 'macos', '-0400');

  print $perlsec;
  print $perlsec2;
  print $epochsec;
  # correct time on Unix:
  print scalar localtime $perlsec;
  # correct time on Mac OS (-0400):
  print scalar localtime $epochsec;

DESCRIPTION

Exports two functions, perl2epoch and epoch2perl. Currently only goes between Perl (Unix) epoch and Mac OS epoch. This is in preparation for an eventual move of Perl to its own universal epoch, so we can get the system epoch of any platform that differs from Perl's.

Epochs

• macos

  Takes additional optional parameter of time zone differential. If time zone differential not supplied, we guess by getting the different between localtime and gmtime with <Time::Local::timelocal>.

BUGS

• Hm. With the above test, scalar localtime $perlsec under my Linux box and scalar localtime $epochsec under my Mac OS box are off by one second from each other. Maybe a leap second thing? Odd.
