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 DateTime Pattern Value object to make any kind of datetime data value accessible to other BACnet devices. The mechanisms by which the value is derived are not visible to the BACnet client. DateTime Pattern objects can be used to represent multiple recurring dates and times based on rules defined by the pattern of individual fields of the date and time, 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: "11:00 every Thursday in any June", or "every day in May 2009". DateTime Pattern Value objects may optionally support intrinsic reporting to facilitate the reporting of fault conditions.
