Site time 14 hours behind ???

Hi, can anyone help please, the time on my Forum and showing on posts etc is 14 hours behind the proper time, it shows members are logged in and posting around 2 o clock in the morning when in fact its around 5 pm...

Any suggestions please ?

Thanks.

P.S. time showing logged into chat is 14 hours behind too....

Thanks very much for your help....and will mark the topic solved.

your welcome
