Re: TZ variable and mod_perl

["Balázs Szabó (dLux)" <dl...@dlux.hu>]

Hi,

Tyler, thank you for the answer, I tried it, and it worked!

Although I am a little bit worried about the ithreads issues with this.
As I read the perlthrtut, it seems that using this module is most
probably will change the whole process' environment, so another
paralelly served request can be affected as well, right? I am asking it,
because I don't know how mod_perl works.

If the user uses a non-threaded MPM, then even if the libperl uses
ithreads, then I guess one apache process only serves one request, so it
must not be a problem, right?

But I guesst with a threaded MPM, setting the TZ environment variable is
not a good idea, since it can affect other running requests.

Are my assumptions right? Can someone confirm them? I would like to put
some warning to the documentation of my module, and tweak it to use as
less tzset as possible...

Thanks in adnvance,

Balázs

It depends.  Take a look at this:
