Manual:Timezone
The default Timezone (tz) for users who have not specified a custom offset may be configured manually.
Default value
editThe default value is taken from the webserver configuration (PHP ini file). For documentation:
https://www.php.net/datetime.configuration#ini.date.timezone
Primary method
edit- 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 = "Asia/Jakarta";
date_default_timezone_set( $wgLocaltimezone );
- Set the $wgLocaltimezone value to the proper value which you can find here. See examples below.
$wgLocaltimezone = "UTC";
$wgLocaltimezone = "Europe/London";
$wgLocaltimezone = "Asia/Taipei";

editThis method has been confirmed by multiple users in situations where the primary method has not worked.
$wgLocaltimezone = "America/Sao_Paulo";
$dtz = new DateTimeZone($wgLocaltimezone);
$dt = new DateTime('now', $dtz);
$wgLocalTZoffset = $dtz->getOffset($dt) / 60;
unset($dtz);
unset($dt);
Alternative methods
editIf you just want to use the local time of your PC, you can add this line in your LocalSettings.php
.
This method is what MediaWiki does by default (see includes/Setup.php); it also avoids problems with daylight savings time:
$wgLocalTZoffset = date("Z") / 60;
Unconfirmed methods
edit- To use your local time zone (say NZDT) put this in
LocalSettings.php
$wgLocalTZoffset = 13 * 60;
- This example may also work
$wgLocaltimezone="Europe/Berlin";
$wgLocalTZoffset = +120;
- In this case the primary method did not take daylight savings time into account. The example below works:
#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, specify the offset in hours, so change all occurrences of '/ 60' to '/ 3600', for example.
$wgLocaltimezone = "Europe/Amsterdam";
#Calculate the timezone offset with UTC
$oldtz = getenv("TZ");
putenv("TZ=$wgLocaltimezone");
$wgLocalTZoffset = date("Z") / 3600;
putenv("TZ=$oldtz");
Combine it with the tip above to make daylight savings work.
- This line is needed in 1.16. It applies to both anonymous and logged in users. Note that you will need to provide the correct values if you want the zone to be selected by default in the timezone dropdown:
$wgDefaultUserOptions['timecorrection'] = 'ZoneInfo|' . (date("I") ? 120 : 60) . '|Europe/Berlin';
Manual timezone specification
editThe primary method needs the server to support the 'tz
' database; some non-GNU hosts don't do that.
However you can supply timezone data manually - unfortunately, only "GMT0" seems to work on Windows.
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";
