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 Time 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. A Time Value object is used to represent a single moment in time. In contrast, the Time Pattern Value object can be used to represent multiple recurring times. Time Value objects may optionally support intrinsic reporting to facilitate the reporting of fault conditions.
