I think a lot of comments are missing the idea that this is a single timezone, not many. The sun is always "up" on some side of the moon. Establishing a common time reference is for coordination of activities on the moon. I imagine that the human-human verbiage with respect to sun angles might go something like, "at 2 MoonST the sun will be at a 4pm position for the rover and a 6pm position for the base. In two days, the sun will have moved about 1.7 hours later for both locations."

> The sun is always "up" on some side of the moon. I don't understand the relevance of this. The sun is always "up" on some side of the Earth, too.

  Many people equate timezone to mean a slice from pole to pole that has a similar Sun angle. If the moon has exactly one timezone, then that timezone describes the time on the entire surface and has no 1:1 analog with sun angle for a given spot within the timezone.

    Wouldn't there be 2 or 4? The day side, the night side, and arguably the twilight sides?

      The moon is tidally locked with the Earth but that doesn’t mean there is always one side that is bright. Ie: the moon has “days” as well… they are just longer than Earth days. By 2 or 4, do you mean time zones? If so, why? Why not just a single coordinated time?

        Yes, I know the moon has days and nights. Each is roughly 2 weeks Earth time. > By 2 or 4, do you mean time zones? yes > If so, why? Why not just a single coordinated time? I'm not proposing, refuting, or endorsing anything. This thread is just me trying to understand what it is you were saying.

I don't believe the moon has a dark side and light side. both sides get light / dark. The moon is locked with earth, not the sun. I could be wrong though

  Thats correct according to my understanding as well.

  the same part of the moon (the far side) always faces away from the earth as you say, and at any time, at least part of the moon is in shadow, which would be a "moving dark side"
