Windows 10: Unpredictable behavior of automatic daylight savings adjustment

I am from Germany and today when I booted into Windows, the time was correctly switched to summer time.

Then at 11:48 Windows changed the time back to winter time and I have no idea why.

The settings should be correct.

I had a similar thing happen years ago and want to prevent it from happening in the future.

Windows 10 automatic daylight savings adjustment not working?

In general, "Adjust for daylight saving time automatically" should always be On. Turning it off is for a few legacy edge cases and a couple of places in the world that don't currently have an appropriate entry in the list of time zones.

Most likely, the system clock isn't set to the correct time. Perhaps there's a problem getting the correct time from the Internet, which is enabled or disabled from the first "Set time automatically" option.

I recommend:

1. Check that your Internet Time Server settings are correct. Try a different time server if necessary.
   
2. Turn on all options, being sure to turn on "Adjust for daylight saving time automatically" before turning on "Set time zone automatically".
   

 

No daylight-saving time auto-adjust?

I am with three UK and can confirm that my phone automatically adjusted for daylight savings. I do not have the option to change clock automatically. I believe it is on by default.

 

"Adjust for daylight saving time automatically" not active in Win 10; time is therefore wrong

The option "Adjust for daylight saving time automatically" is greyed out, so I cannot turn it on. Even with the "Set time automatically" option turned off, the "Adjust for daylight saving time automatically" remains inactive (greyed out.)

The account I'm using (the only one on the system), has administrator privileges.

This is a new and fully patched Win 10 system with no other apparent problems.
