Sorry; I'm lost now. When you ask if I'm "ahead or behind", the question I find myself at a loss to answer is "relative to what"? I'm missing some context.
Right here, right now the time is GMT+13 hours. That's 12 hours for the timezone (the Easternmost edge of the world) plus another hour for daylight saving (it goes without saying that daylight saving happens at different times of the year in the southern hemisphere than it does in the northern).
All my clocks around here are displaying GMT+13. My handy NISTime client says
Local Standard Time - UTC = 13:00
Computer Time: 2002-12-27 (361) 23:10:12 (11:10:12 pm).
(But like I said, the difference between UTC and GMT is not worth noting.)
If I were to post right now though; then when I looked at the time stamp attached to this post in the forum, it would say that it was posted at 10:10 pm.
So, if it's a matter of who's ahead or behind, the clocks on these forums are one hour behind (all the time displays are reading one hour earlier than they should be).
In short, vBulletin doesn't recognise Daylight Saving time.
