PROV-ISSUE-43 (derivation-time): Deriviation should have  associated time [Conceptual Model]

Raised by: Paul Groth
On product: Conceptual Model

Other relationships have time associated with them (e.g. use, generation, control)

There is no optional time associated with derivation. 

Suggested resolution is to add the following to the definition of isDerivedFrom:

-  May contain a "derived from time" t, the time or time intervals when b1 was derived from b2

Example:
isDerivedFrom(b1,b2, t)
