The moon's day length is so long that it wouldn't make any sense for any crewed mission to use it, they're going to need their own lights on an arbitrary 24 hour cycle anyway, so there's no reason not to have every future crewed mission there use the same one

I mean, this is the real answer here, but you can't just put them on UTC because of the relativity like we were discussing elsewhere, so it would still have to be a separate time zone for programming and timekeeping purposes, even if humans won't be able to tell the difference

So, just plonk an atomic clock on the moon and call that moon time. Ocasionally synchronize moon time with UTC.

That's pretty close to what they're doing. The tricky bit is detailing how you convert a lunar timestamp to a terrestrial timestamp.

Jostling clocks with things like leap seconds turns out to be more trouble than it's really worth. Better to just let them get out of sync but be able to precisely define what the drift is.
