Nope, no time zones. Just one time zone that is "the moon". But somebody somewhere needs to make a standard for that, and this is it.

Still tho, how about a prime meridian centered on where Neil Armstrong first set foot ?

They don't need any meridians. The entire place will be one zone. The time will be the same everywhere.

The problem is that the time there will move very slightly differently than here on earth, because of the lower gravity, to the tune of 60 ms per day. That's almost a second every two weeks.

So the question isn't "what time do we set the clocks to?" but "what time will it be an hour from now?" Have a leap-second every few weeks?

> Have a leap-second every few weeks?

Well, we have the software ready for it.

And yes, a prime meridian is not necessary, but NASA loves to name things. How about the Wright-Gagarin-Armstrong Meridian ?

60 µs per day, not ms.
