Time zone differences

I’ve run into a bit of a strange glitch. When I’m logged into the forum, everything looks fine—the time offset is set to +1. But the moment I log out, the clock shifts to 0. For instance, if I’m logged in, I’ll see the last post in thread xx was made at 10:51 AM, but once I sign out, it suddenly says 9:51 AM. I have no idea how to sync these up. I’ve combed through the settings, and everything seems to be configured correctly.



Except for this one detail at the bottom:



It indicates the time zone is GMT + 2, even though the displayed time feels right.

I'm not sure if there's a connection here, or if there's actually a way to fix it if there is.
