How do I...Change the local timezone settings?

would you please tell me how to synchronize the time between the wiki and the host? thx.

I tried it, but nothing changed.
I changed the value of "-07;00" to "-06:00" and nothing. I just want to time back an hour.how can i do it?
thanks!

The settings file is just a PHP script, so you have access to anything it's capable of. This ought to synchronize it with the server in PHP 5.1.3 and up.

$wgDefaultTimezone = date('P');

Whether there's anything wrong with doing this I don't know. edited 23:55, 1 Apr 2009
