Topic: OT: Strange time-stamping on forum posts

When I peruse the forum posts without logging in, I notice that the time-stamp on all the posts is 1 hour ahead of the (correct) time-stamp that displays on the selfsame posts whenever I am logged in! For example a post at 14.00 hrs will display at 15.00 hrs when I'm not logged in. Thus, some posts seem to arrive from the future  :-)

This strange behavior occurs on both my computers. There are no aberrations with posts on other web forums. Any simple explanation? FWIW I'm in the GMT+1 West European time zone.
