in reply to time() off

I've seen something similar if the environment variable 'TZ' is set. This is consistent on both *nix and Windows:
F:\>perl -e "print scalar localtime" Thu Sep 9 08:18:24 2004 F:\>set TZ=MST F:\>perl -e "print scalar localtime" Thu Sep 9 14:19:25 2004
And on *nix:
$perl -e "print scalar localtime" Thu Sep 9 08:20:26 2004 $export TZ=mst $perl -e "print scalar localtime" Thu Sep 9 14:20:35 2004
