It's not a fault. They have updated the timezone perameters for both the site itself and members profiles. I had already corrected the site timezone but not my own profile.
If all members could go into their profile (on main bar just below the logo, then click preferences you can alter your timezone accordingly.
Its nice that they thought to make it easier for folk from different continents or members going abroad to other timezones etc but fair warning would have helped. I thought i was going mad! LOL
Hope this helps folks. :D
