Setting the WorkDayStartTime and WorkDayEndTime properties applies different coloring to the hours that are not in the specified range, however the displayed time span is controlled by the DayStartTime and DayEndTime properties and if these are not set the default (8:00 AM - 6:00PM) time span will be shown.
