Property Frames and Temporal Relations

The head of a property frame can be related to another frame by a temporal relation. This is useful, for example, when a property of an object or other entity changes over time--say, at %time_1, a car is red, and at %time_2, it is black (as a result of being painted, catching fire, etc).

Whenever it is not useful for a property frame to have a temporal relation, it generally does not.
