Current State Invalidated Event

Public Custom Event CurrentStateInvalidated As EventHandler
Although this event occurs when the ClockState becomes invalid, that doesn't necessarily mean the ClockState changed: a Clock that switches from Active to Filling and then back to Active in the same tick will cause this event to fire, but its CurrentState property won't actually change.
