I have a new Gigabyte motherboard (B660M ds3h ax) that loses 2 hours on the clock in the bios. It does this when the computer is turned off overnight. I do think it loses exactly 2 hours. What can I do to fix this? Thanks.

Which distro and version of Linux are you using? Is it dual boot with Windows? What is the hardware, a Raspberry Pi? – user68186 Nov 07 '22 at 02:53

I prefer to edit the Windows registry to change Windows to UTC time. – C.S.Cameron Nov 09 '22 at 04:49

Exactly 2 hours smells like the bios and computer disagree about local time vs utc and/or which timezone you're in. The hwclock
command can help you make them agree with each other.

I do apologize. I am using Win 11. It looks like the bios is reporting right. I changed the setting in os to automatic. I changed my time zone to central. – Trekiej-2 Nov 08 '22 at 19:51

It also looks like I needed to correct the time in bios each time it started. It is good now. – Trekiej-2 Nov 08 '22 at 19:54

Edit Windows Registry using the method shown in the link in user68186's comment, in the first answer under the paragraph Make Windows use UTC. This fix has worked for me for many years. – C.S.Cameron Nov 10 '22 at 03:18
