On the lunar surface a single Earth day is roughly 56 microseconds shorter than on our home planet.
That can lead to significant inconsistencies over time.
NASA is working with its international partners to come up with a method for tracking time on the moon.

Sundials have kept humans on schedule for millennia.
Time passes slower the faster a person or spacecraft is moving, according to Einstein’s theory of special relativity.
Astronauts at the International Space Station (ISS) can use Earth time to stay on schedule.
Atomic clocks are ultra-precise instruments that use the vibration of atoms to measure the passage of time.
NASA's Lunar Reconnaissance Orbiter captured this view of Malapert Massif on March 03, 2023.
The lunar mountain is a potential landing site for Artemis III, a NASA mission that could launch as soon as 2026 and put astronauts on the moon for the first time in decades.
