Abstract
The invention is a Clock for synchronizing operations within a high-speed, distributed data processing network. The clock is actually a distributed system comprising a Central Clock and multiple Site Clock Interface Units (SCIU's) which are connected by means of a fiber optic star network and which operate under control of separate clock software. The presently preferred embodiment is as a part of the flight simulation system now in current use at the National Aeronautics and Space Administration (NASA) Langley Research Center (LaRC), Hampton, Va.
