On my installation the timezone in the ~~~~ signature is displayed as "(New Zealand Daylight Time)". This is pretty cumbersome. I'd prefer it display "(NZDT)" or no timezone at all. I've tried Googling mediawiki time zone but all the hits are around setting the offset, not the name. I've also tried searching the MediaWiki installation for a configuration file with timezone names in it, but no luck.
I'm using MediaWiki 1.5.1, PHP 4.3.8, MySQL 4.0.20a-debug on Windows XP Professional.
In my LocalSettings.php, I have the following setting:
$wgLocalTZoffset = 13;
I guess there must be a mapping somewhere from 13 to "New Zealand Daylight Time", although I don't know how it knows I'm not using Tonga Standard Time. Maybe the O/S supplies the timezone names. Any ideas?
