Hmnnn, now I a even more confused. My post shows the correct time stamp, but I can clearlŷ see others that are stamped with date/time yet to happen! Maybe the forum uses user's own pc time, stamp and some of these are wrong?. Not exactly 'end of the world stuff', but I am curious....
As said above you can set your time zone and whether or not to automatically adjust for daylight saving in your user control panel. Go to "edit options"
Don't forget to save any changes.
I dont know what the default is if you are reading while not logged in
