    >NASA will coordinate with U.S. government stakeholders, partners, and international standards organizations to establish a Coordinated Lunar Time (LTC) following a policy directive from the White House in April. The agency’s Space Communication and Navigation (SCaN) program is leading efforts on creating a coordinated time, which will enable a future lunar ecosystem that could be scalable to other locations in our solar system.

    >The lunar time will be determined by a weighted average of atomic clocks at the moon, similar to how scientists calculate Earth’s globally recognized Coordinated Universal Time (UTC). Exactly where at the moon is still to be determined, since current analysis indicates that [atomic clocks](https://phys.org/tags/atomic+clocks/) placed at the moon’s surface will appear to ‘tick’ faster by [microseconds](https://phys.org/tags/microseconds/) per day. A microsecond is one millionth of a second. NASA and its partners are currently researching which mathematical models will be best for establishing a lunar time.
