time::epoch
Epoch(3) User Contributed Perl Documentation Epoch(3)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
o 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
o 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.
