Hello Matthias,
thenk you for your tips. I already know both and I have already tried to solve my problem with it. I also found the table where the time is stored (ns_qrtz_cron_triggers).
However, there are several dependencies on other tables regarding start and end times as well as the value "next run" from the Scheduled Task. Therefore, it is difficult to see whether manual changes are needed and do not break anything.
Thus, the idea of Ron is easier implement.
There is already a FR 0170550 with the desire to change the behavior via the GUI.
Best regards
Stephan
