Hi monks, I need your help.

I wrote a cgi script that basically needs to transform UTC time to CEST time and vice versa. Using my basic skills and Google I came around with something like this to initialize my local timezone:

use Time::Local;
use POSIX qw(tzset);
$ENV{TZ} = 'Europe/Berlin';
tzset();

Reading a UTC timestamp from a database and transforming it to localtime works great when running the skript locally, but when called as a cgi from a browser, the same script fails in doing so and all dates are UTC.

Adding some debug code I found out that the tzset call does not seem to affect the system timezone. Here is the code:

($std, $dst) = POSIX::tzname();
system ("echo $std x $dst > /tmp/cgi.out");
system ("echo $ENV{TZ}   >> /tmp/cgi.out");
[download]

The output reads "CET x CEST Europe/Berlin" when run locally and "UTC x Europe/Berlin" when run as cgi. Do you have any idea why this happens?
