A TimeInterval object representing the time range of the time cells.
If an appointment lasts several days, visually it can be divided into several parts - one for each day. In this case, each appointment part is represented by a particular AppointmentViewInfo object. The Interval property specifies the time interval of the time cells covered by the appointment on a particular day. The AppointmentViewInfo.AppointmentInterval property specifies the time interval of the whole appointment.
The following picture shows an appointment which starts on one day and finishes on another, but does not last a whole day. This appointment is divided into two parts displayed in the Day View. The DayView.ShowWorkTimeOnly property is set to true, so the time interval from 6 PM to 9AM is hidden.
