There is something odd about the time stamps on posts. Today one is stamped at 10:30 AM today, and I was reading it at 7:00 AM EDT! Most other time stamps would indicate that the poster is online during the night!
And my post above was submitted at 7:12 AM, but bears an 11:12 AM time stamp!
Time zone setting on your computer? The server's?
It looks like you're seeing GMT times. Check your own computer's clock, or maybe there's an incorrect timezone setting somewhere. As you can see, the same times seem to be displayed correctly for me.
BTW I'm in the Central timezone, so the times are correct for me.
