No, in the case that the interval *has* expired (maybe 10 minutes ago, maybe 3 hours ago) once the app. REGAINS control, it will fire. If it was 3 hours ago and you have 2hours set, then you will get 2 immediate fires.

This is true regardless of the interval. With a very short interval you will get as many fires as have occurred too, all at once, upon the app. regaining control.
