The Forum Clock is set by you the Member to suit your local time.
Here is how to do it ...
Go to "Profile" found in the menu near the top of the page.
Within "Profile" go to "Look and Layout Preferences" under "Modify Profile"
Within "Look and Layout Preferences" scroll down and see "Time Offset"
Click "Auto Detect"
and then scroll down and click "Change Profile"
Thats it, your clock should now be showing your correct local time.
Cheers
