Unfortunately the desired behavior is currently not supported by the ScheduleView as the TimelineViewDefinition is designed to display the whole days. When you set the DayStartTime and DayEndTime properties they applied on the whole VisibleDays range (DayStartTime is applied to first day and DayEndTime is applied to the last day from the range).
However we have already logged that as feature request in our public issue tracking system, so you can vote and track its status on the link below:
