[German]We have 2020, and Windows 10 still struggling to switch to the correct daylight savings time 2020, at least in Europe. Some machine are still in ‘winter time’, others changed correctly to daylight saving time, but went to a wrong time some hours later.
This weekend Europe changed from winter time to daylight savings time (summer time). But Windows 10 systems struggles to switch to the correct time.
A reader’s mail about issues
German blog reader Dekre has sent me an email today. He mentioned, that the time settings on his Windows 10 Pro system is broken. He wrote:
today we are switching to daylight savings time (CEST)
My PC clock was displayed correctly at startup today at 07:25 CEST. One hour later it jumped back again. The automatic time synchronization then reports errors.
Is it the same with others? Win10 pro. I have now switched to manual time setting without synchronization.
I booted my Windows 10 Pro test system. The change to daylight saving time worked. And I didn’t recognized some changes later – but the system hasn’t been running for an hour.
More feedback from German blog readers
After I’ve published the German article, I received feedback from many people. On some systems, the switch to daylight saving time worked flawless. But some readers confirmed the observation from blog reader Dekre.
Alfred Neumann: Got the same problem here. At first it is true and after a while, had not paid attention to the time, the hour was changed again. Win 10 Pro 1909 x64
Andreas: I have a Win 10 v1809 Professional. After about 3 hours of operation I noticed that the computer shows the winter time. I then deactivated and reactivated the setting “Update time automatically”, after that the time was correct.
Volker: For me Win 64 1909: First changed this morning, then after about an hour again winter time, then manual synchronization, then permanently changed to summer time. That with all 3 computers in our household.
Smagjus: Two systems with Windows 10 (Home and Edu) are booted with summer time and one hour after the boot, they erroneously returned to winter time by themselves. Both use time.windows.com. Both were set to automatically adjust the time and daylight saving time. A manual “Synchronize now” resulted in a return to daylight saving time.
Ärgere das Böse!: This morning the time was right, now it’s not.
I used to sync it manually, now it’s right again.
Manual sync was used to set the time correctly. So there’s something wrong with Windows 10. In the following comments there are also several hints that the change to daylight saving time did not work automatically.

And blog reader Karl has published the above tweet – where he points out incorrect time changes. No idea what went wrong – even with systems that didn’t change to daylight saving time. Windows 10 seems broken in this respect.
