Good luck, Mike! =D (Yeah, we went ahead one hour, not too sure why the date has gone back one, though).

You chose the wrong time zone. The one you selected is 1 day behind your actual time zone, hence the posted time showing as 1 day (tz difference) + 1 hour (dst difference) behind. Try Pacific/Auckland instead.

Don't worry, thats a problem I have all the time.

Yeah, I'm pretty sure GMT+12 should be the time that I'm currently at. Considering Auckland and Wellington fall under the time zone GMT+12:00. *shrug*
