twice today I look at the time and it's off by 2 hours ahead

I fixed it twice now.
I fixed it around 3 pn and now look at pc and it says 930pm when it is only 730pm

settings showing here, it was showing 930pm
To fix. I flip set time toggled off and on

This sometimes happens if the bios time is out of sync with windows time.

ok, but convenient excuse seeing we had a time change recently. maybe the bios time does not adjust itself for daylight savings, but first time I have seen this. I have restarted pc today several times. Mostly this PC is on 24 hours a day

It has been off recently and not had this happen.

Settings / Time / Click on Time Zone.
Click downward arrow and select correct time zone.

It's weird, but you need to set things like this. Then it behaves like it should.
And the BIOS clock does what it's supposed to as well.

I've found Windows time is sometimes inaccurate and have to do a manual synch - must be a bug.

Hi,
Dual booting with linux will do this and sometimes more than just 2hrs lol

Same with Dual Boot Win11 Pro and Win11 Insider Pro. Insider advances 2 hours, instead of 1.

But it may be wise to note down (or take photo's) the settings of the BIOS first.
Or take screenshots (the easiest way to record your BIOS settings).
See this link for that:

What I do to quickly verify time is have 2 clocks set in Time and Date, one local time and the other UTC/GMT. Knowing I'm in MT zone which is normally 7 hours different but 6 hours different in DST all I have to do is hover the mouse over the clock in the Notification Area to verify. I worked in aviation for over 30 years and that was a daily need.

For me has occurred only during spring time change on two other Windows 10 desktop computers over the last few years.

Just had a thought clear my foggy brain for a moment. What about a VPN being in use? It might be connecting through a site in a different time zone.

Insider time advances 2 hours, non insiders 1 hour.

I am not into Sci-Fi, but perhaps this is an example of time travel.

Now if I could just get the computer to revert 50+ years and take me with it!

Thanks to the author of the question.
I did some reading on this topic and found how to replace the time server in Windows Home.
I installed a first level NTP server with fast response.

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
NtpServer

I synchronize manually anyway, just got curious.

I've had time desynchronize by about forty seconds over the course of a year.
