The results will be used by the various official agencies of the two continents in improving their time synchronization. J.HE PROBLEM of correlating the time of day at widely separated locations with great accuracy is one that has absorbed chronologists, navigators, astronomers and cartographers for hundreds of years. As vehicles grow faster and the range of exploration reaches far into outer space, more accurate time determinations become increasingly necessary. Precise timing and coordination of events far apart may determine the success of precise mapping operations, satellite orbital place ment, astronomical observations, or missile land ings. In recent years, intercontinental time of day
