  Given an appointment was created for 2016-11-03T13:00 until 2016-11-03T14:00 called Appointment
    And the appointment was renamed to Renamed appointment
  When we reschedule the appointment to 2016-11-03T15:00 until 2016-11-03T16:00
  Then an AppointmentRescheduled event is appended with the following properties:
    | Start time       | End time         |
    | 2016-11-03T15:00 | 2016-11-03T16:00 |
