Translate the TimeMachine extension if it is available at translatewiki.net

The TimeMachine extension allows you to browse a wiki as it was at any given date. By going to Special:TimeMachine, you can set a date and from then on whenever you visit a page, you will see the first revision previous to that date. By visiting Special:TimeMachine again, or emptying your cookies, you can return to browsing the wiki as always.

The design and implementation of TimeMachine are described here.


  • Download and move the extracted TimeMachine folder to your extensions/ directory.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/TimeMachine
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'TimeMachine' );
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
