Future Assertion Time

This chapter introduces the concept of future assertion time. It explains the semantics of this concept, and responds to the objection that there is not and cannot be any such thing as future assertion time. It shows how the implementation of standard assertion time can be extended to include the management of future assertion time. It introduces the concept of temporal locking, and shows that without it, a situation parallel to the paradoxes of time travel can occur in databases.
