Help: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:

#Set Default Timezone
$wgLocaltimezone = "America/Los_Angeles";
$oldtz = getenv("TZ");
putenv("TZ=$wgLocaltimezone");
$wgLocalTZoffset = date("Z") / 3600;
putenv("TZ=$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.

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") / 3600;

---

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

$wgLocalTZoffset = 13;

---

• In my case the primary method did not take daylight savings 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");
$wgLocalTZoffset = date("Z") / 3600 + Date("I");
putenv("TZ=$oldtz");

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