Having troubles with your server clock/calendar on the forum thread? Some strange dates and times appearing and moving around must mean it's the bewitching season.
When in the forums, go to your User Control Panel (link is all the way to the left on the top forum nav bar). Then go to edit settings, and you will see a timezone setting there. Right now everyone is 4 hours ahead, but hopefully I will get this fixed shortly.
It should be back to normal now. There was a bug in the third party software upgrade, which screwed up the forum times.
