Yeah, this is a general issue I've put to the back of my mind to be honest, there are about 3 levels of "time" involved in the server, and it seems the boards most low level clock is taken from the server, hosted abroad. We then use an offset to set the local time to that of the UK, but users also have their own offset modification. despite a lot of playing I've still not identified which time is used for the stats, and what's more confusing is that the time that YOU see the posting posted at is different to the time that I see it posted at, as it seems to be converted to your own offset.
Confused? I am.
