This OPC UA Property, of DataType UInteger, represents the BACnet property Interval_Offset.

The Interval_Offset value indicates an offset in minutes from the period specified for time synchronization and the time that the synchronization requests are actually sent. The value used shall be the Interval_Offset modulo the value of Time_Synchronization_Interval. For example, if the Time_Synchronization_Interval is 30 and the Interval_Offset is 31, then the offset shall be 1.
