One possible explanation is that your phone is synchronising its clock setting with your pc/pda. My laptop is more than a hour slower previously, and it kept putting the clock on the phone back 1 hour. Then I realised that it is synchronising with the PC.
hello people ,
the clock lagging behind is the first comment I put up.When you sync it with the pc using the nokia pc software or some times get emails or put some thing like world clock it will happen.
win XP user just transfer files with the wireless software and you will not havea problem when you sync.
