I was just going through FAQs and noticed this:
How do I change my settings?
If you are a registered user, all your settings are stored in the board database. To alter them, visit your User Control Panel; a link can usually be found at the top of board pages. This system will allow you to change all your settings and preferences.
The times are not correct!
It is possible the time displayed is from a timezone different from the one you are in. If this is the case, visit your User Control Panel and change your timezone to match your particular area, e.g. London, Paris, New York, Sydney, etc. Please note that changing the timezone, like most settings, can only be done by registered users. If you are not registered, this is a good time to do so.
I changed the timezone and the time is still wrong!
If you are sure you have set the timezone and Summer Time/DST correctly and the time is still incorrect, then the time stored on the server clock is incorrect. Please notify an administrator to correct the problem.
So I guess the third FAQ is what I'm experiencing.
