Segundo a documentação do protocolo BACnet:

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 Date Pattern Value object to make any kind of date data value accessible to other BACnet devices. The mechanisms by which the value is derived are not visible to the BACnet client. Date Pattern objects can be used to represent multiple recurring dates based on rules defined by the pattern of individual fields of the date, some of which can be special values like "even months", or "don't care", which matches any value in that field. Examples of possibilities would be: "every Thursday in May of any year", or "every day in May 2009". Date Pattern Value objects may optionally support intrinsic reporting to facilitate the reporting of fault conditions.
