if the end and start time are exactly the same
Scheduler will have problems with events which has zero length. To be rendered correctly in all views event must have different start and end dates.
Scheduler seems to work pretty well with the same start and end times. It is only Month view, where I need to update the display, to only show the start time, if the dates are exactly the same.
See shot attached - “Task” should only show the start time.
