Solved Losing time - Clock sometimes out of sync on startup since installing Windows 11 24H2

Hi all,

Since installing Windows 11 24H2, the time in Windows is sometimes out of sync, losing a about 0.1-0.2 seconds per minute, which adds up over the course of a day (and is super frustrating when working).

The CMOS battery has been changed to a new one (the old battery proved to still be holding charge, though).

This issue does not occur on Windows 11 23H2.

Motherboard, CPU and RAM all about 2 months old: X670E Gigabyte Aorus Master (Bios v. F33d), Ryzen 7 7800X3D, G.Skill Trident Z 6000 CL30.

I haven't been able to work out the exact conditions for when this occurs.

I have flashed older bios versions (F21, F22, F33c) and cleared CMOS, etc. in addition to changing the battery.

I have recorded the time on the motherboard BIOS ticking over, and it does not lose time when I have observed it.

If I reboot to BIOS and set the time manually after I notice the issue, the next boot of Windows keeps the time. Sometimes, though, Windows doesn't sync the slipping time to BIOS - so sometimes the BIOS time is still correct even if it is a few to many seconds out in Windows.

When the symptom does occur, I notice that the time can start falling behind even if just at the Windows login/lock screen (I always sign out before shutting down due to having two Windows accounts - both local, one at administrator level).

It's a strange and also infuriating issue.

Has anyone else experienced this or spotted whether this is a known issue with Windows 11 24H2?

Regards,

Tim

Hello @thatstimming and welcome to ElevenForum.


I'm on the latest stable version of Win 11 24H2, and I don't have problems with losing time.
These are my setting, related to that...
(I'm in the east coast USA time zone)

Hey Steve. Thanks for confirming. I spotted that program and I'm using it - but I appreciate the reiteration to use it as a workaround.

It's of some comfort that I'm not the only one experiencing the issue.

Do you/others know what the cause of the bug is?

Do any of your motherboard/CPU/RAM match mine?

Much appreciated to you (and to Ghot) for engaging with my post.

Fill out your system spec! I reported the bug the MS ages ago. Let's hope they fix it.

Checked out your PC. No similar components. So, just a dirty Windows bug.

Thanks for the input.

I looked in Task Scheduler and there were two tasks in Microsoft...Windows...Time Synchroniation. They were not running as scheduled.
I deleted both of them and created a new task that runs daily.

I followed this guide and now my clock is accurate to within a second.

Make Windows synchronize time more often

I used to use SocketWatchf in Windows XP/7/10 but in Windows 11, I am using Thinking Man Software - Dimension 4 v5.3 - I'll take a look at NetTime. Does NetTime have a system tray icon so you can see when it updates?

I change it to the National Institute of Standards and Technology time server as there are times the windows server has issues.

I've never had issues with... time.windows.com

But I would think that nist should be fine.

Hi all. This appears somewhat fixed. I no longer have any loss of time when signed into a Windows account. The time on lock screen can still fall behind at times, though (fixed by just signing in).

Can anyone else correlate?

Definitely not fixed. I still noticed it on my X670E / 7800X3D system (before sending off the motherboard due to a separate issue). I'm back to using my Z390 / 9900K system for now.
