ABSTRACT:
A system for timing intervals in a computer. The system provides an interval timing service for processes running in a computer system. The timing service supports a potentially large number of interval timers by using "timing wheels" that "turn" at different periods. The time base for the fastest turning wheel can be an interrupt event or some other hardware or software control.
