System clock resetting after I installed a UPS.

Recently I attached a UPS to my system. Before I go to bed, I hit to power button on the UPS which cuts the power to the outlets (note up to now I always unplugged the computer before and have had no problems with the system time resetting so I don't think it's the CMOS battery.) When I power the system up the next day I noticed that the system time was reset, one time though it had the right time but it had 2011 for the year. I do have the computer and UPS connected by the USB cable so I can monitor the UPS status. Any ideas?
EDIT: The situation has become slightly more bizarre, when I turned off my computer and unplugged it to see if the clock would reset on me, when I went to plug it back in my computer just decided to boot up! The clock settings were retained though.

Just some personal experience to throw out there. Not sure it really helps. lol
