If you click on "User CP" above the "Post Reply" button on the top left, it takes you to "Your Control Panel." In the left column, click on "Edit Options" and scroll down. One of the paragraphs is for Date & Time, and you can reset the time to your time zone.
So, for some reason, my time setting defaulted back to Mid-European..... I've changed it back again, but anyone have any ideas on what would cause that to happen?
