On some categories of events we would like to create a field showing the duration of an event ie Endtime - Starttime.
I can't see in custom fields how to define a field with time (hh:ss).
Has anybody ever tried this?
Is it possible to calculate this field from the Start and End times of the event
ie duration = eventenddatetime-eventstartdatetime
eg duration is 3 if eventstartdatetime is 20mar2020:17:00:00 and eventenddatetime is 20mar2020:14:00:00
