The clock on my computer is approximately 15 minutes slow. If I manually change it, or force an online update, it briefly shows the correct time before reverting back to the incorrect time.
I was going to suggest changing your bios battery but if it's changing while on then that's out. How are you connecting to the internet wireless or wired just curious. In your Date and Time Settings under Internet Time mine shows: Sync with Internet server and in the drop down box: (time.windows.com)
Double check that and get back to us.

My paranoid theory? Some time-limited trial software didn't want me changing the time / date to avoid it running out. Haha, never heard of that before, though.
Well then change the bios to 3 minutes faster and see if you get closer to the actual time. lol
