Windows 8 clock randomly jumps forward one hour.

Fenster

Bit of a head-scratcher, this. TL;DR: The system clock in Windows 8 insistently jumps forward one hours, at least twice an hour. I've ruled out obvious causes and applied common fixes.

Longer version, as above:

• Windows 8 Professional 64-bit
• System is set up with a dual-boot between this and Linux
• System clock randomly jumps forward by exactly sixty one minutes and thirty seconds.
• The clock ONLY jumps forward in Windows. Both Linux and the BIOS show the correct time.
• Timezone is set to UTC with daylight savings enabled.
• When I sync via NTP, the time resets correctly. As a workaround, I have a task set to sync every sixty minutes.

I have so far:

• Verified the registry and GUI timezone settings.
• Applied a registry fix to force Windows 8 to use the BIOS clock time.
• Ruled out the presence of malware.
• Applied a workaround where my clock will sync via NTP once an hour.
• Verified language and region settings (Ireland).

Beyond that, material on the Internet is sparse. 99% of the times, this problem is caused by an incorrect timezone setting-their clock changes forward when it syncs via NTP. Mine changes back to the correct time when I sync.

Anyone?

Why? Windows already stores time using local time. You'd have to set your Linux distro to use local time. Instead of that you could set Windows to use UTC, but I'm not sure if they got that working properly.

I haven't touched the Linux installation since this problem cropped up, so I can rule that out as a cause. I also tried setting it to UTC (RealTimeIsUniversal). Didn't help.

Disable the Windows Time service and see if the problem persists.

Now this I hadn't considered. I'll try it, thanks!

It just happened again. The service was stopped and disabled.

Maybe Tron is trying to send you a message about how to get into his locker so he can get something he needs to save the digital world and the PIN is 6130

I too would have suggested see if changing how it picks up the time via internet, but another option is to perform an OS Refresh

That's like deciding to move house because the mantle clock is off by an hour.

Is the time zone set correctly?

Fenster

Yes, per the original post.

More like fumigating: OS Refresh in windows 8 doesn't affect files or apps. Regular software will be uninstalled but a list of removed programs is created on your desktop. Refresh rebuilds the OS files and restores settings to their defaults.

I gave up in the end, and went back to Windows 7. This was just one of about six incessant issues that were deal-breakers.
