Manual:Timezone

The default Timezone (tz) for users who have not specified a custom offset may be configured manually.

Primary Method

 * Create a backup copy of the LocalSettings.php file found in your install directory
 * Edit LocalSettings.php and add the following code:

$wgLocaltimezone = "America/Los_Angeles"; $oldtz = getenv("TZ"); putenv("TZ=$wgLocaltimezone"); $wgLocalTZoffset = date("Z") / 60; putenv("TZ=$oldtz"); $wgLocaltimezone = "Europe/London"; $wgLocaltimezone = "Asia/Taipei";
 * 1) Set Default Timezone
 * 1) Versions before 1.7.0 used $wgLocalTZoffset as hours.
 * 2) After 1.7.0 offset as minutes
 * Set the '$wgLocaltimezone' value to the proper value which you can find here. See examples below.

''Note: This timezone will be used in:
 * ~ signatures
 * timestamps in recentchanges
 * timestamps in history''

Note: Upload and deletion logs will probably still be listed in UTC Note: This method has been confirmed to work on MediaWiki: 1.5.6. Note: The $wgLocalTZoffset configuration changed from hours to minutes in MediaWiki: 1.7.0.

Unconfirmed Methods
$wgLocalTZoffset = date("Z") / 60;
 * If you just want to use the local time of your PC, you can just add this line in your LocalSettings.php:

This is what I'm using, it works exactly as you'd expect. --Iam8up 05:58, 19 June 2007 (UTC)


 * To use your local time zone (say NZDT) put this in LocalSettings.php

$wgLocalTZoffset = 13 * 60;

$wgLocaltimezone = "Europe/Amsterdam";
 * In my case the primary method did not take daylight saving time into account. The next example works for me:
 * 1) Set Default Timezone

$oldtz = getenv("TZ"); putenv("TZ=$wgLocaltimezone"); $wgLocalTZoffset = date("Z") / 60 + date("I") * 60; putenv("TZ=$oldtz");
 * 1) Calculate the timezone offset with UTC

$wgLocaltimezone = "Europe/Amsterdam"; $oldtz = getenv("TZ"); putenv("TZ=$wgLocaltimezone"); $wgLocalTZoffset = date("Z") / 3600; putenv("TZ=$oldtz"); I cannot test daylightsavings right now, so you probably have to combine it with the tip above to make that work.
 * To make it work in 1.5.8 I had to specify the offset in hours, so change all occurences of '/ 60' to '/ 3600', e.g.
 * 1) Calculate the timezone offset with UTC

Note: The methods in this section are unconfirmed and may not work properly.

Manual Timezone Specification
The primary method needs the server to support the 'tz' database; some non-GNU hosts don't do that. You can supply timezone data manually; see here for details. E.g. use $wgLocaltimezone = "CET-1CEST-2,M3.5.0/2,M10.5.0/2";
 * instead of

$wgLocaltimezone = "Europe/Budapest";
 * or

$wgLocaltimezone = "AEST-9,M10.5.0/3,M4.1.0/3";
 * instead of

$wgLocaltimezone = "Australia/Sydney";
