Hello Stefan, please, open ticket a upstream if you still want to get the problem resolved.
Obviously currently all entries in sispmctl are considered as having the same UTC offset as the current time zone of the user and switches of the time zones are not considered. Please, explain in the ticket in which format you want enter the following timestamps in sispmctl: 2019-10-27T02:30:00+02:00 2019-10-27T02:30:00+01:00 Just entering data and time is not enough because both are 02:30 AM in Berlin. One is before and the other after the switch to winter timer. I wonder which user will fancy entering complete timestamps with time zone information. Best regards Heinrich Schuchardt
