Dual Boot, Time keeps changing on Bootup, as if it's UTC but not really

Hi All,

I have Windows Dual Boot with Linux, and whenever I boot into Windows (11), I have to re-set the time again. It looks to be going back to UTC, but it says Eastern. The correct time zone is indeed Eastern. To fix, all I have to do is right click on the click, click "Adjust Date and Time", and turn "Set time automatically" back off, then back on. This fixes the time immediately.

It actually says the right time zone from the start at the top "Time Zone (UTC-05:00) Eastern Time (US & Canada)", so the timezone is actually right.. But if I reboot it's back to the old time.

Also, "Set Time Zone Automatically" is disabled and turned off. It says "Last successful time synchronization:" was 3 days ago, so apparently turning the option off/on above doesn't count as a synchronization!

It's also worth noting this is a brand new installation of Windows 11, and was installed to a different HD partition after Linux. Windows shows up in the GRUB bootloader, (it is not default, I have to cursor down and select it). I did not have this issue prior to reinstalling Windows.

Does the time issue happen to anyone else? This is tricky to Google because all that comes up is how to set your time.

Thank you in Advance,

Dan Chase

    It uses the BIOS clock to measure time when WIndows is turned off. But it's the Time Servers that sync's Windows time. Did you change yours to see if that solves it?

    It not then you can try updating the BIOs and chipset drivers from the PC or motherboard maker's Support Downloads web page for your exact model, to see if that helps.

    There is more about how the Windows clock interacts with the CMOS clock in BIOS here:

    But do you think the time sync in windows is ever supposed to go back to the motherboard?

    Thanks Greg!

    I realized something when I booted up today, I went into the Motherboard BIOS setup, and the clock was 4 hours ahead! Apparently, the Windows time sync isn't going back to the motherboard to set the time in BIOS - is that normal? Maybe I'm missing drivers, or maybe it never has - any idea if it's supposed to?

    This explains a lot!

    Hi Danny. I'm Greg, 10 years awarded Windows MVP, here to help you.

    These issues can often be solved by changing the Windows 11 Time Server it sync's with:
