LTE440: China's lunar clock aims to sync Moon time with relativity
Chinese researchers unveiled LTE440, a lunar time ephemeris that uses Lunar Coordinate Time and relativistic corrections to convert Earth time to Moon time with long-term accuracy (about 1,000 years). Built on Kopeikin’s TCL framework, it aims to coordinate lunar time for navigation and communication during future Moon missions and could become an international benchmark alongside NASA and ESA efforts to standardize lunar clocks, helping prevent time-zone chaos in space.
