Clock fix, replacing CMOS, confirmed

[Demix]

So I have done this to 2 consoles and can confirm clock is synced to correct time. I had console on 7.55 that showed dec 31 1979, i updated to 9.0 but it did not fix the time. What did make it work is removing the hard drive, reformatting it, and reinstalling 9.0 via USB. At the setup page it displayed correct time and saved the correct time.
