According to the BACnet protocol documentation:

Defines a standardized object whose properties represent the externally visible characteristics of a named data value in a BACnet device. A BACnet device can use a Time Pattern Value object to make any kind of time data value accessible to other BACnet devices. The mechanisms by which the value is derived are not visible to the BACnet client. Time Pattern objects can be used to represent multiple recurring times based on rules defined by the pattern of individual fields of the time, some of which may be "don't care", which matches any value in that field. Examples of possibilities would be: "every minute of the 11 o'clock hour of the day", or "the thirteenth minute of any hour". Time Pattern Value objects may optionally support intrinsic reporting to facilitate the reporting of fault conditions.

Objects of type timepatternValue have the following properties:

•ackedTransitions
