A String expression that indicates the starting time of the day. For instance,
the "08:00" indicates 08:00 AM, while the "16:00" indicates
the 08:00 PM.
By default, the DayStartTime property is "08:00",
which indicates that the day starts at 8:00 AM. The DayEndTime
property specifies the time to end the day. The TimeZone property can be used to
programmatically update the time zone. The MajorTimeRuler
property indicates the time to increment the major rulers, while the MinorTimeRuler
property specifies the time to increment the minor rulers. The DateTimeFromPoint/TimeFromPoint
properties can be used to get the date/time from the cursor.
