A work colleague's computer is having an unusual problem. Whenever the computer is restarted the time and gets set to approximately 1.5 days previous. The timezone is set correctly, but the computer does not connect to the internet to sync the time anyway. I figure if it was a CMOS/battery problem the time would reset to the manufacture date or 1970 or something. Why does it want to always lag behind by more than 24 hours?
It is a Windows 8 laptop.
UPDATE: Before it seemed that it was going back 1.5 days. But now as I am investigating and restarting the computer I see it is more complicated. I can't make sense of it to explain what it is doing. It is not simply running slow. When the computer is on the clock seems to proceed at the correct pace. Just now when I restarted twice it reset to 11:50am, even though I let the clock run to 11:51 in between. Just prior to that it seemed like the time fell behind by about 30 minutes in the space of just about 15 minutes while installing updates.
