POSIX::strftime with gmtime

[pelagic]

Hello co_monks,
I'm a bit puzzeled about the behaviour of different versions of strftime. I got the following code:

use strict;
use POSIX qw(strftime);
print "Perl:      $]\n";
print "POSIX:     $POSIX::VERSION\n";

my $today = strftime("%d %m %Y %H:%M:%S", gmtime(time));
print 'scalar     gmtime:    ', scalar gmtime(time), "\n";
print "strftime'd gmtime:    $today\n";

$today    = strftime("%d %m %Y %H:%M:%S", localtime(time));
print 'scalar     localtime: ', scalar localtime(time), "\n";
print "strftime'd localtime: $today\n";

Depending on what Perl version (and POSIX version) I use I get different output for gmtime.

Perl:      5.00503
POSIX:     1.02
scalar     gmtime:    Tue Jun 14 12:18:04 2005
strftime'd gmtime:    14 06 2005 13:18:04
scalar     localtime: Tue Jun 14 14:18:04 2005
strftime'd localtime: 14 06 2005 14:18:04

Perl:      5.008006
POSIX:     1.08
scalar     gmtime:    Tue Jun 14 12:18:04 2005
strftime'd gmtime:    14 06 2005 12:18:04
scalar     localtime: Tue Jun 14 14:18:04 2005
strftime'd localtime: 14 06 2005 14:18:04

Any hints about that? And b.t.w. '12:18:04' is the correct GMT.
