Windows Task Scheduler "Synchronize accross time zones" does not work as expected - can anyone explain?

Hi,

This weekend, EU switched from standard time to DST. I have several tasks in my windows 10 task scheduler that need to be aligned with UTC, thus independent of DST changes.

Therefore I checked the "Synchronize accross time zones" option within the scheduled task options.

I configured the task in a way that it's first runtime is on 1.1.2022 18:00 every Monday (thus standard time is used). The scheduled tasks windows displayed the next runtime correctly. Now with DST in effect, the scheduled task overview window displays the next runtime correctly as 28th March 19:00. So the task keeps being aligned with UTC. However the task is executed one hour early at 28th March 18:00. When 19:00 passes, the task is not repeated, and the displayed time when the task is run next is moved ahead 1 week.

Out of curiosity I just changed the task to repeat daily instead of every Monday. With the daily setting the task is started at the correct time! Amazing! So there seems to be some sort of bug when using the the "once per week on a specific day option".

Maybe the issue fixes itself next week, however this is a very strange, annoying an inconsistent behavior.

    Hi @Dark-Sider667

    Several steps you could have a try:

    1.Try tick /untick the option Synchronize across time zones;
    2.Reboot the device;
    3.Delete the job and recreate it;
    4.Install all the update patches.
