America does not move to daylight savings time until this weekend (April 6th).
In any case, the forum time is based on *your* location - to change this, go to 'user cp' at the top of the page, click on the 'User options' link, and scroll down to the 'Time offset' field. Change this to whatever time zone you're currently in. In my case (I'm in the UK, and our clocks went forward last weekend), I'm set to GMT+1. I guess you'd either be the same, or else GMT+2.
