For some reason my forum seems to think it is an hour earlier than the current time (it thinks it's 3:10GMT where as it's actually 4:10 GMT.)
Could anyone please tell me how I could go about fixing this?
It sounds like something to do with the daylight savings setting. Either enable or disable it.
Enabling/Disabling DST in the ACP has no effect what so ever.
Check the settings in your User CP too.
Is this affecting all your members?
Yes, all the forum's members are an hour behind. Everyone has DST enabled as they should do I believe.
If you're sure all the settings are correct then it's probably that the server clock is set incorrectly - you'll need to contact your host about that.
Gah, I feared as much. Thanks for the help.
