Moon time is slightly faster than Earth time (as in reality itself runs faster) so either Moon time has -1 leap seconds every 50 years, or earth needs to skip ahead to keep pace with the Moon.
A lunar day from sunrise to sunrise is a month long. Two weeks of night and then two weeks or day. What a weird way to live that would be! Could the body become accustomed to extra long days?

Wow, your math is pretty much on the money!
Also, lunar days, hours, and minutes will have different definition than Earth. Or, if using Earth time, must account for the time dilation due to relativistic effects. Also, Russia and China will claim part of the moon with their own time standard which is meant to serve as a universal 'space time' and has different definitions for hours, days and months than NASA
Actually, no. Introdice earthlight savings. Daylight savings is to see the sunlight more, but on the moon you have a much cooler blue ball to look at. Thus, wherever the earth is visible the clock is set forward 1 hour and as the earth leaves the view it is set back one hour.
Actually since the same part of the moon is always facing the earth, that would be easy to implement, as the regions with additional time wouldn’t change.
Oh boy DST on a database where we parse out most but not all dates as strings in large clobs so you can’t possibly know which dates are DST and which dates are UTC without checking every single one in a 20/30 year old system.
Kill me
At least for all Earth time zones, a delta second is equal to a delta second no matter which Earthly time zone you're in. Thanks to Einstein's general relativity, that's not gonna be true on the moon lol.
So, here's how I think I'd do it. It'd be like UTC in that every time zone gets an offset. Except now there's a second offset, or a coefficient really. So, your time zones are degree 1 polynomials. E.g. instead of UTC-7, you now have UTCx1.0000587-7. Except, you probably don't want to write all those zeros, so maybe agree on a notation like UTCx587₇ -7 or maybe UTC-7+5.87m% (b/c millipercents, why not?). Except also, you're using UTC as an base, and that's based on the speed time moves on Earth. It feels more scientific/future proof to give Earth an offset too, and make the baseline zero g and stationary. So, maybe UTC gets defined as a relativistic offset of a new standard. Anyway, it's a second dimension to the offset.
Why do we even have time zones? Why can't we all just use the same one? Who cares what number the clock says when I wake up, as long as I get to go back to bed 3 hours after that time.
Travel used to be a bigger deal. I can hop in my car and drive a time zone over with little effort. Before timezones we all just went basically by sundial. It made it hard to know what time you'd meet someone in another town. At the same time, people didn't want to completely change their scheduled times so we just grouped them together.
That’s what time zones accomplish on a small scale. Before time zones, each town and city would have their own time zones.
Time zones changed it such that gigantic areas of land would be grouped together with the same time.
Due to general relativity, time moves a bit faster on the moon than on Earth.
So it's not really a time zone in a traditional sense, it'd just be a slightly slower clock such that it syncs up with UTC back on Earth without drifting.
Time runs 0.0000587 seconds per day slower on the moon. It's not like a leapyear correction here on earth it's much harder to account for. But that is more or less what they want, a way to use earth time on the moon which means figuring out a way to keep synchronisation between clocks on the moon and time on earth.
I know a sys clock with a -6.79x10^-10 s/s for the moon and a way to let the computer know it's on the moon and account for the journey in-between which would be a gradual shift from earth seconds to moon seconds.
Leapyears were bad enough never mind space faring nonsense
My guess is they'll just make it sync up with GMT or UTC. Time runs faster on the moon, so if they set their clocks to either they'd drift relative to the earth
So a time zone for the moon, but we still can’t decide on whether or not to keep DSL. Not to mention if we do get rid of it, will we run on standard or DSL permanently. Right, ok, cool…priorities, man.

Nasa plans to make a timezone for the moon, and timezones have been historically difficult for developers
But, clocks have nothing to do with timezones. Just set the rate at which your clock ticks on the moon so it matches earth utc.
That clock won't be accurate outside of the moon ofc
Thats basically what they are doing, its just easier to code that as a time zone, since its already implemented.
Otherwise you would need a time zone *and* a seperate planet zone.
So UTC gets split into UTCE and UTCEL ("Universal Time Coordinated Earth" and "Universal Time Coordinated Earth Luna")
Mercury and Mars will have to fight over UTCM.
Of course if we ever reach the stars, we'll need another denomination. Throw in an S for "Sol" there somewhere.

A new timezone for the moon is being created by NASA

The moon is a conspiracy theory trying to make us use JS on the backend
Can't wait for relativistic timing attacks
Stop giving them ideas
That's what big python wants you to think.
Those snakes
LoL it's so easy, you just install MoonJS, MoonQL and MoonRedux, NextMoon and MoonPureFunc
Nooooooo get away from mee
Don't forget MoonmentJS.
Moonvelte
the moon is a pidgeon
Become a flat earther so that the moon's time zone matches the zone it's hovering over
Isn't the Moon a piece of cheese?
Please also introduce daylight saving on the moon. Please!
Done
and make sure that only some of the timezones use DST
[удалено]
i wonder what kind of leap seconds we are going to deal with...
Moon time is slightly faster than Earth time (as in reality itself runs faster) so either Moon time has -1 leap seconds every 50 years, or earth needs to skip ahead to keep pace with the Moon.
oh, gravity; you a crazy b.
I was going to say it might be because it is smaller is a lunar day is shorter than an Earth day, but then I remember the moon is tidally locked.
A lunar day from sunrise to sunrise is a month long. Two weeks of night and then two weeks or day. What a weird way to live that would be! Could the body become accustomed to extra long days?

Make one 45mins and the other 2.5 hrs

Masochists be like this

To be fair, no one but NASA's likely to need it anytime soon. They've already adopted sol standards for martian rovers and whatnot.
Don't look at me. I voted for a second round of daylight savings that partially overlaps with the current one and starts at noon on Easter.
I am looking at you, with various less-than-savory intents.
At least for all Earth time zones, a delta second is equal to a delta second no matter which Earthly time zone you're in. Thanks to Einstein's general relativity, that's not gonna be true on the moon lol.
We already account for the difference in satellites and space probes. It's also just a fairly simple formula so it's not that hard to code.

In a place far awayyyy
All the iOS devs worrying about time zones on the moon, like it will ever be relevant to them.
Shots fired
The moon operates in utc. You’re welcome.
Let me tell you about relativity…..

Leap seconds. Leap seconds everywhere.
I wish Talks about a certain CLT

Do i need to say it again... 😆
Say it
Isn't the moon tidally locked with Earth? How would the time work then? Because a rotation and revolution would be the same amount.
Due to general relativity, time moves a bit faster on the moon than on Earth. So it's not really a time zone in a traditional sense, it'd just be a slightly slower clock such that it syncs up with UTC back on Earth without drifting.
I have no idea how this would work
Write it in a shared C library or GTFO.
Make me
Can someone explain why they don't just use GMT like all the airlines already use?

Something about loosing a second in 50 years or so

Can't make timezone shit worse than it already is.
Watch
it’s time! https://en.wikipedia.org/wiki/InterPlanetary_File_System?wprov=sfti1
It's not just one timezones. They are dividing it on multiple time zones. Yikes
Some get daylight savings 😂
I will be using it as the only time zone
*Flat Moon Society has entered the chat...*
Tbh I'm beginning to believe them
Calm down, it’ll be UTC.
I thought it was CLT Central lunar time
Nobody would ever be able find it
Oh wait it's actually coordinated lunar time But it somehow abbreviated to LTC
Distraught Tom Scott noises from the corner
The classic
Actually, time zones aren't so hard. Just don't think that it will be easy and "my app is very simple, can cut corners"
UTC or we end the US ruling the world. We got enough between earth and Mars seconds
Please explain j don't understand

Oh I get it. But why on earth 😉 would they do that? Lol do they like have no other task for the programmers at NASA?
Time on the moon moves a tiny bit faster due to general relativity, so without it clocks will drift.
But, clocks have nothing to do with timezones. Just set the rate at which your clock ticks on the moon so it matches earth utc. That clock won't be accurate outside of the moon ofc
From what I understand I think that's basically what they're doing
Thats basically what they are doing, its just easier to code that as a time zone, since its already implemented. Otherwise you would need a time zone *and* a seperate planet zone.
I doubt it's directly related to NASA developers They just intend to make one
I pity future developers that'll have to add the multiple time zones of multiple non earth worlds
Devin furiously taking notes
Timezone on the moon, on the mars, on the moon of the mars
I am in vietnam with GMT+7 and my colleagues in US in GMT -6. Usually have standup meeting at midnight my time 😭
I know the feeling
Will the moon have a leap year?!?!
Kinda But in 1,576,800,000 years
Hmmm yes.. we'll just... Ah fuck it, the moon is just going to be UTC now.
Utc - 1 second every 50 years basically
Ok… ok… this genuinely made me lol out loud.
Hehe
The reality: import moontime
I supported a product some time ago that had a Mars standard time setting. Apparently the devs were thinking ahead of time.
Wow

AI can’t replace us if we just keeping making things harder!
But only certain portions of the moon.
ackshually google says some scottish canadian invented time zones so you can't blame us americans for this one
