How to easily fix the clock offset in your Forum profile.
Hover your mouse cursor over the Profile entry in the different Options bar above (Home is highlighted), click on the Forum Profile selection.
In the Forum Profile, hover your mouse cursor over the Modify Profile entry, click on Look and Layout.
The displayed screen will have a Time Offset. Click the (auto detect) highlight. It should set your Time Offset automatically; else manually set it to -7 (if on PST, -4 for EST, etc.).
Click the Change profile button on the bottom of the page to save it.
