The duration for a recurring Appointment.
If you are creating a recurring Appointment, it is not necessary to set the PatternStartTime, Duration, or PatternEndTime, as the AppointmentRecurrence will get these values from the Appointment.
However, if you do set these values, they will override the Start, Duration, and End properties set on the Appointment.
