While porting code using DateTime to Windows I got a "Cannot determine local time zone" error. The code is like: 
DateTime->from_epoch(epoch => $t, time_zone => 'local');

Is there a way to get a time zone from Windows? From strftime I got something semi-useful: 
C:\>perl -MPOSIX=strftime -le "print strftime(q(%Z), localtime)"
AUS Central Standard Time

I decided to calculate the difference between localtime and gmtime for now. Is there a better alternative? 
#!/usr/bin/perl -w
use strict;
use DateTime::Duration;

my ($lh, $lm) = (localtime)[2,1];
my ($gh, $gm) = (gmtime)[2,1];

my $dur = DateTime::Duration->new( hours => ($lh-$gh), minutes => ($lm
+-$gm));
print sprintf "%+02.2d%02d\n", $dur->in_units('hours','minutes');

Thanks, Brad
