If I am in the formula of Kontrollfeld, Beginn, go to formatting, klick Use the same time zone (GMT) for all collaborators the whole column is one hour behind Uhrzeit, Beginn der Veranstaltung. Fine.
But if I click Use the same time zone (GMT) for all collaborators in that formula again, all fields in that column are working – except that single field, that adds one hour …
