NASA is working on creating a time zone for the moon, aiming to standardize timekeeping for precision space-travel calculations. The Coordinated Lunar Time (CLT) project aims to establish a lunar time zone similar to Coordinated Universal Time (UTC), which regulates clocks on Earth. However, NASA faces a challenge in accounting for minute differences in gravity and velocity between Earth and the moon, which can impact calculations by 56 microseconds per day. This tiny difference may seem insignificant but can have significant effects on space missions.
