If time editing is enabled in Vista and Classic modes (see CalendarView), the Calendar Control displays
a time edit box and a clock face, which reflects the time entered.

To customize the time editor's appearance and behavior settings, use the CalendarTimeProperties property, which is of the RepositoryItemTimeEdit type. For instance, the CalendarTimeProperties.Mask (RepositoryItemTextEdit.Mask) property specifies
which portions of a time value can be edited in the time box.
