Allow the same start and endtime in a new appointments
When I dont know the duration of a new appointment, I am always create a duration of 0 minutes, that means the start and endtime in my old app (outlook) was the same. Now I have changed because outlook has more and more bugs, the support is only bad and therefore I have changed to onecalendar and it is great. But a 0 minutes date is not possibilty here.
