My date and time on my system is stuck on one date and will only work properly for one hour at a time. i.e. I set the date for June 20th and two days later I still show June 20th. Also the time goes only in 1 hour cycles, i.e. 10:15am - 11:15am and instead of going to 11:16 it starts back over at 10:15. Could this be my motherboard battery?
