Thanks so much for the replies. Thought it must be something like that, but couldn't see any change when I put a number in the box, so thought I'd better post the question, even if I did post it in the wrong forum, I think. Sorry.
Original post was:
In MY STUFF under PREFERENCES near the bottom it shows Current server time is: Mon Apr 20 2009 04:39 PM and there is an option to
Choose your time offset in hours: (..,-2,-1,0,1,2,..)
Can someone explain what this is and how to use it? Thanks in advance.
