How can I change the display format of date and time.
As far as I understood all found information on this topic, this will bee set at the time of installation from the systems settings.
Currently I have at least 2 different formats.
One in the Flow

and a different one in the History

I need to change it, because I want to have the ISO-format or the DD-MM-YYY format
Please no questions why I need it.
