note 10139 added to date

Setting the TZ environment variable does not change the date display in PHP4(tested on 4.03p1) unless you do a call to time() after the putenv. The only PHP4 datetime function that calls tzset() to update the timezone from the TZ environment variable seems to be time(). So in PHP4 I do putenv('TZ=Australia/Adelaide'); time(); // Used for sideeffect - does tzset print strftime("%Z\n"); putenv('TZ=Europe/Riga'); time(); // Used for sideeffect - does tzset print strftime("%Z\n"); http://www.php.net/manual/function.date.php
