Time zones and $_ENV vs getenv

Hello people. Argentina changed timezones (Oct 19th), just two weeks ago, and, as PHP has a separate table, I forgot to change the zones both in my machine and on the server. I did so yesterday, and have some problems. Here's what I did: 1) Downloaded the latest timezonedb (2008.9), compiled and installed it locally and on the server. Apparently no problem there. 2) I have a calendar on my pages (http://www.jcoppens.com/kayak/peperina/agenda.php&uniz=1) which shows the unix time stamp if the cursor is above a date (just to help debugging). The stamps coincide till Oct 19th, then differ by one hour (as compared to my PC). At the remote server, the time seems correct (-0200), on my machine it isn't (-0300). I _did_ restart my apache, and yes, the php.ini is correct. One strange thing I noticed (on both my machine and the server) is that $_ENV['TZ'] was empty, while getenv('TZ') was correctly set (America/Argentina/Cordoba). I'm confused... Can someone point me to some more tests I could do? Thanks, John
