Interesting. For me the standard cygwin perl works okay.
$ perl test-1.pl
Winter (delta should be +1 h)
ZULU : 2007-12-13 11:47:02 Zulu
LOCAL: 2007-12-13 12:47:02 Europe/Prague
Summer (delta should be +2 h)
ZULU : 2007-06-13 11:47:02 Zulu
LOCAL: 2007-06-13 13:47:02 Europe/Prague
$ printenv TZ
Windows XP, currently in the GMT-5 timezone
