NASA is tasked by the US government to develop Coordinated Lunar Time (LTC) for the Artemis program.

LTC creation is essential for accurate operations on the Moon, accounting for relativistic time differences.

An atomic clock on the Moon will form the basis of LTC, with NASA's Deep Space Atomic Clock leading the way.

The European Space Agency supports establishing a unified lunar time standard.

The Artemis 3 mission is planned to land humans on the Moon by 2026, necessitating LTC for mission support.

While the International Space Station will use coordinated universal time, LTC's implementation date is undecided.

The international response to the US-led LTC initiative, including from China and Russia, is currently unclear.

There will be no daylight saving time adjustments on the Moon.
