Question

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.

Hello, did you find any solution for DST switching on a weekly schedule, except having the tasks running daily? Kind wishes, Heiko

Windows 11 Scheduler has stopped updating the "next run time" on a daily schedule.

This program is so quirky that I am reluctant to waste more time on it.

Can anyone recommend an alternative ?.

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.

Have you seen these similar threads?

Hello,

the system is up-to-date. The issue is also present on newly created jobs and also persists after restarting the machine. I have seen the other threads, however none of the threads specifically lists a specific recurring type as the issue.

Can you reproduce the issue with your system?

1) create a A task to start cmd or calc.
2) set first run on January 1st 2022 (so it defaults to standard time)
3) select run every week, check the "current" day of week and set a time runtime 2 minutes in ahead of your current system time (given that you are now in daylight saving time)
4) check synchronize across timezones

observe, that the task starts 1 hour early, although the task likst shows the next runtime correctly in 1 hour and 2 minutes!

now create a new task, but insted of chosing run once week, chose daily and set the runtime 2 minutes ahead of your current system time. You will observe that the task starts in 1 hour and 2 minutes as intended - the displayed next runtime is also correct.
