Would time zones even be necessary on the Moon ? Sunrise and sunset occur on a scale of Earth days, not Earth hours.

- jfengel 3y agoNope, 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.
- euroderf 3y agoStill tho, how about a prime meridian centered on where Neil Armstrong first set foot ?
- jfengel 3y agoThey 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?
