Out of curiosity I just changed the task to repeat daily instead of every Monday. When 19:00 passes, the task is not repeated, and the displayed time when the task is run next is moved ahead 1 week. However the task is executed one hour early at 28th March 18:00. So the task keeps being aligned with UTC. Now with DST in effect, the scheduled task overview window displays the next runtime correctly as 28th March 19:00. The scheduled tasks windows displayed the next runtime correctly. I configured the task in a way that it's first runtime is on 18:00 every Monday (thus standard time is used). Therefore I checked the "Synchronize accross time zones" option within the scheduled task options. I have several tasks in my windows 10 task scheduler that need to be aligned with UTC, thus independent of DST changes. In conclusion, with "Synchronize across time zones", depending on when you've defined the job, it might run +1 hour or -1 hour in advance.This weekend, EU switched from standard time to DST. If you define the job during the summer time, at 20:00 => this is translated to 18:00 UTC => this means that out of summer time period (let's say November), the job will still start at 18:00 UTC = 19:00 local time (CET). Somewhere during the summer time period (let's say in June) the task will still attempt to start at 19:00 UTC and this means that the task will start at 21:00 local time (Central Europe Summer Time = CEST = UTC+2). This job will run as expected at 20:00 local time, until the summer time will be in place. The setting "Synchronize across time zones" is quite tricky and not self-explanatory at all.Īs you were saying, it will launch the task as if not summer time was active throught the year.įor example, if you are located in Paris (Central Europe Time = CET = UTC+1) and you have set somewhere in December (out of summer time period) a job to start at 20:00, the server will know to start it at the equivalent 19:00 UTC time. Et voila, I synchronized across time zones! Next I created a scheduled task on this remote server that is triggered by such an event (this is possible since Windows Server 2008). So I can log an event on the remote server as well. It accepts a parameter for specifying a remote server. This command logs an event in the eventlog. The second one launches the command "eventcreate". I solved it by creating 2 scheduled tasks on the server in europe. I need a server in Asia(no DST) to be synchronized with a server in Europe (with DST) and the latter is leading in the schedule. In effect this means that both servers will always launch the tasks as if no DST was active thoughout the year. When a server is in a timezone with current DST then it only compensates for this DST time-shift. That means that both servers need to have a scheduled task configured with the local time for each server. The setting "Synchronize across time zones" only takes DST into account. What is the specified behaviour when using the checkbox? How can I achieve the desired synchronization even in case of DST clock changes in one of the time zones?

All replies (2) The task runs however as the entered local time. I intended to use the new checkbox option "Synchronizing across time zones" and assumed that the specified schedule time needed to entered as UTC-time. I have two servers 2008 R2 in different time zones that need synchronization of a mutual scheduled task.
