ZoneDateTime Mediawiki extension

Recently built this new MediaWiki Extension so that the users of our irc.chekmate.org network would be able to know the time for a specific server.

This extension is super simple. It just determines the time differnce from GMT and then displays it.

Modify as you see fit.

Note: Most up to date version of this extension can be found at: http://www.chekmate.org/wiki/index.php/Projects
