Does time matter when you are in space?

The White House wants the US space agency, Nasa, to develop a new time zone for the Moon - Coordinated Lunar Time.

The US government hopes the new time will help keep national and private efforts to reach the moon co-ordinated.

Former astronaut, Chris Hadfield, has flown three space missions and also served as commander of the International Space Station. He also went on two spacewalks.

He joins presenter James Reynolds to explain why it is important that there is a time zone in space and how he dealt with time when he was on the International Space Station.
