Massive object velocity method for clock synchronization

A clock synchronization method is presented based on temporal calibration obtained via the propagation of a massive object. The calibrated massive object velocity combined with launch and receive synchronizations allows synchronization of a distal clock. This approach is an alternative to classical electromagnetic synchronization methods and the slow clock transport concept. The method is presented as an analog to electromagnetic clock synchronization. Relativistic effects and local synchronization between the object and clock are discussed.
