    "description": "This field contains the offset this service needs for the appointment, expressed in units of time relative to the scheduled start date/time. This field allows the application to identify that the service is required for the appointment at a different time than the appointment's start date/time. The first component contains the offset amount. An offset of zero (0), or an unvalued field indicates that the service is required at the start date/time of the appointment.\r\n\r\nA positive offset (an unsigned or positive number) indicates that the service is required after the appointment's start date/time.  Specifying a negative offset indicates that the service is required prior to the specified start date/time of the appointment.  Negative offsets are allowed, and sites should clearly define the effect of a negative offset on the appointment's start date/time. \r\n\r\nThis field is conditionally required.  If a value for AIS-5-Start date/time offset is not provided, then a value is required for this field.  To specify that there is no difference between the appointment's start date/time and the resource's start date/time either replicate the appointment's start date/time into this field, or specify an offset of zero (0) in AIS-5-Start date/time offset and any valid time unit code in AIS-6-Start date/time offset units",
