Date keeps on switching to nov 2020 every now and then

I am on surface pro, is there anyway to fix this, because of this i cannot update dom0 or install packages without running the sudo date command because i run into cert not yet valid error

Bad CMOS battery maybe ?

Does it happen on other OS’s ?

Just in case someone is facing this issue in the future;
I had the same problem on a Thinkpad with a liberated bios.

Solution is (if it’s not the cmos battery) to set the date for linux and then for hardware in dom0, immediately reboot and then it should remain as set (moving forward as time should of course).

Mine just switched 1 hour off for the past few days. I was wondering how to fix it.
