Re: setting timezone in windows

Oops. Bad on me; somehow convinced myself - despite a clear-enough question - that OP wanted to set system time:
~~This is really a question for a w32 forum;~~ note that svenXY's method gives a conversion... but does NOT set system TZ.
However, if setting TZ is an acceptable alternate:

Diligent search here (or with ppm, if you're using Active State) for WIN::API may help you.

or, otherwise,

ppm's WIN32API-File-Time may (I have not checked it) also provide some guidance/clues.

Me again... localtime is a built in perl function, I'm trying to modify its behaviour, so I think this question is a valid Perl question.Neverthless, maybe I'd have to ask first to ActiveState... Substract a constant to time() every time I call it IMHO it's not the answer. It's not the porpouse of localtime, if it were we only need gmtime. WIN32API-File-Time is related to file's times. Not work here. The only way to change the behaviour is to set from the DOS shell the TZ variable, that is: > set TZ=GTM 3 and then run the script. Setting it by system("set TZ=..") doesn't seems to work neigther. I think it's a fail in the localtime implementation that only check TZ before the interpreter compile the code (setting TZ by system or %ENV in a BEGIN block doesn't work). Sorry, I'm know that win$ sucks. It's the real problem here.I'll try to solve it for a little while more before give up. Thanks for the answers.	[reply]
