{{#if:|Other languages:}} Template:H-langs: {{#if: Help||}}}} The default Timezone (tz) for users who have not specified a custom offset may be configured manually.

[edit] Primary Method

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

#Set Default Timezone
$wgLocaltimezone = "America/Los_Angeles";
$oldtz = getenv("TZ");
putenv("TZ=$wgLocaltimezone");
# Versions before 1.7.0 used $wgLocalTZoffset as hours.
# After 1.7.0 offset as minutes
$wgLocalTZoffset = date("Z") / 60;
putenv("TZ=$oldtz");

• Set the '$wgLocaltimezone' value to the proper value which you can find here. See examples below.

$wgLocaltimezone = "Europe/London";
$wgLocaltimezone = "Asia/Taipei";

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.

[edit] Unconfirmed Methods

• If you just want to use the local time of your PC, you can just add this line in your LocalSettings.php:

$wgLocalTZoffset = date("Z") / 60;

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;

---

• This example may also work great

$wgLocaltimezone="Europe/Berlin";
$wgLocalTZoffset = +2;

• In my case the primary method did not take daylight saving time into account. The next example works for me:

#Set Default Timezone
$wgLocaltimezone = "Europe/Amsterdam";

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

---

• 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.

$wgLocaltimezone = "Europe/Amsterdam";
#Calculate the timezone offset with UTC
$oldtz = getenv("TZ");
putenv("TZ=$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.

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

[edit] 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";
