After fudging the forum and server time zones for a few years I've now rationalised them. So the server and forum are now set to run in UTC. That might mean that your profile time offset may be wrong.
If the post times on the forum seem wrong then go into your Profile in the Look & Layout (?) section and adjust the time offset until the posts show the correct time. You can try the 'auto' option but it sometimes gets it wrong.
The chances are that the times will never be right for everyone and that if you have DST in your area then you'll probably have to adjust the offset (manually) when DST starts and ends, but at least the forum will be consistently on UTC now
