There is no time DateTimeCtrl is derived from EditDate, but finally it should be derived from EditDateTime which does not exist in upp yet. Such class should allow to enter date and time or only date or only time.
I only wonder if returning time is needed. And I wonder if popuped calendar in time mode should have a slider (or sth like that) to allow visually select the time.
We have to answer these questions or simply rename DateTimeCtrl to DateCtrl or DatePicker.
Well if I need time in my Apps i use two WithDropChoice<EditIntSpin> : one for the hours and one for the minutes the first dropchoice contains the numbers 0-23 and the second 5,10,15,....,55.
