This will be useful for any tests that test objects with time-dependent behavior. It will allow such tests to be written in such a way that their outcome is more repeatable (less flaky), and will also allow such tests to finish quicker. For example, a test for STUN timeout doesn't need to wait the full timeout interval in real time; it can simply advance the simulated clock.
