At boot, RTC will go out of sync.
Seems that even even when I run restart64 two times it sometimes goes out of sync. It behaves erratically.
I ran restart64 like 3 or 4 times and left cpu-z timers tool running for 5h and it was good.
Windows is using TSC so I think I will just forget about this or I will go crazy trying to find out what causes it.
if you boot without gpu driver?
Doesn't seem to happen. Well there is nothing I can do anyway. Most probably this happens to more people.
And like I said, Windows doesn't use RTC anymore.

I tried the registry edit:
RTX 2080 is found in
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{70FE5764-A86F-11F0-8D8D-40C73CFB3FE7}\0002
I tried "DisableDynamicPstate"=dword:00000001 in 0001 and 0000 and it doesnt work, power state still stays at P5 at idle, after restart

try this one...
Force P-State 0 with the registry key below (reboot required)
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000" /v "DisableDynamicPstate" /t REG_DWORD /d "1" /

Oh, I realised I made a mistake. I have 0000, 0001, and 0002. RTX 2080 is under 0002 for me, Intel HD under 0001. When I add the registry value to 0002 it works.
Thanks Babluga for helping
