Hi guys,
just a quick note, I update the World Time plugin. This update only includes bug fixes.
Update should be pretty simple, you can pretty much replace all the files. The only one that is obviously not included is the settings.php, which you created in the control panel and that will therefore stay untouched on your server (do not replace the entire folder, that would delete your settings.php and you would have to set it up again).
Enjoy
