Thanks to everyone for alerting us that the time was incorrect. The servers clock was off by about 20 minutes, we have fixed it so it should be right on.
As for those of you that are off by an hour or more, your profile can be updated to reflect your time zone, so that all the post reflect your current time, where ever you might be
To change your timezone in your profile:
Then scroll down towards the bottom of the page in the "Date & Time Options"
Change the "Time offset" option to reflect your timezone
That should do it, hope that helps
