The White House wants US space agency Nasa to develop a new time zone for the Moon – Coordinated Lunar Time (LTC).
Because of the different gravitational field strength on the Moon, time moves quicker there relative to Earth – 58.7 microseconds every day.
This might not seem like much, but it can have a significant impact when trying to synchronise spacecraft.
The US government hopes the new time will help keep national and private efforts to reach the moon co-ordinated.’
