I have mine set for -5 EST and it's 11:35 PM right now.
Darned if the post time doesn't show 6:42 PM. The time settings in the profile seem to indicate that the software is expecting the server to be set for GMT, and then people chose their respective time zones from that. Based on the fact that I am off by five hours, I would say that the server is on EDT so it's throwing the software settings off.
