Based on a completely superficial review there are three almost guaranteed ways to become unhinged; studying infinities, refactoring legacy code, and working with timezones.
Lmao I love how he just gets more and more flabbergasted throughout the whole video. Truly an accurate depiction of dealing with timezones (which I’m unfortunately dealing with right now!)
No different than any other project the PM/PO team cooks up. Tons of work for no user base.
Why… why is the world like this?
Because the world is seen and directed by layers upon layers of abstractions that get divorced from reality but do give monetary benefits when manipulated in some way.
Our sorrow, despondency, and terror are their sustenance.
We’ve gone too far. Everyone just switch to UTC please. Yes, it means some will go to bed at 2pm and get up at 10pm, so what.
go to bed at 2pm and get up at 10pm
While we are making reasonable demands, stop using 12 hour time. Sincerely, everyone else.
And please, get all countries to actually start properly accepting ISO 8601 format for dates as a mandatory universal standard…

I’m just saying, but we did.
Pretty much every electronic thing you own that resembles a computer (phones, tablets, laptops, desktops, even your damned TV) uses UTC. Every. Single. One. Translates that time to “local” whenever it needs to.
So when your TV goes from 9:32 to 9:33, is just showing the converted time from UTC each time.
Almost every device on the planet is keeping time in UTC.
Just because you don’t see UTC time on your device, doesn’t mean that’s not what’s happening. I had an issue where I needed to get into my computer’s bios for something, as soon as the BIOS loaded and showed the time, it was “wrong” because it was in UTC. I’m sure plenty of newer BIOS dialogs are configured to account for timezones now, so yeah. I might be unique in this. It’s still there.
But would the moon work on a 24 hour system at all?
I can’t believe I just typed that as a serious comment
Didn’t Bajor have a 28 hour day? I’m now voting for Universal Bajoran Time
If you’re setting moon time to the day/night cycle of the moon, yeah, it would actually have a much longer day, from what I understand.
I might be wrong, but to my best understanding, the moon is tidally locked to the earth, meaning the same side of the moon is always facing the surface of our planet. Which means the rotation of the moon, and the length of a day on the moon would be tied to how fast it orbits the earth.
You can tell the duration of an orbit by simply following the moon cycle (“new” moon (midnight) through “full” moon (noon) and back to a “new” moon. Based on this, unless I’ve made a serious error in my logic, a moon day would be something like 20-30 earth days.
If I Google it, the moon orbits earth approximately every 27.3 days. Which is about 665h 12m… Give or take a few hours.
Our entire concept of time, days, months, and years, breaks on the moon. On earth, an hour is 1/24th of a rotation of the planet. A day is one full day/night cycle, a year is one orbit around the sun.
When you transpose this principle to the moon, am hour is 1/24th of a rotation of the moon, which happens to be 1/24th of a year, which is one orbital rotation around the earth. So one day = one year on the moon.
So how do we measure time on the moon in a way that isn’t completely insane? The only logical thing I can think of is to fundamentally lock the time zone of the moon to the earth. That the date, and maybe even the time, isn’t based on the moon, but rather transposed from some definition of the same on earth.
This also leads me into a rant/discussion about time in SciFi. Once you leave the orbit and reference point of Earth, what is a day? An hour? A year? You have no point of reference to base such notions of time. Why is there a “night shift” in programs like Star Trek? Why is there really only one captain? Why does everything on these shows seem to occur during their idea of “daytime”?
Then there negotiating with some alien race and say they’ll reconvene tomorrow about something… Tomorrow, based on what? You’re in space. It makes sense if they’re in orbit of a planet, but then you get to see standoffs in the middle of fucking nothing, and they’re like “you have 24 hours to decide”. Okay. 24 hours based on what exactly?
I appreciated MiB’s take on this in the film. They defined not only how much time they had to return the galaxy, but in what format the time was being counted in. Which they could calculate and adjust to earth time.
This all sets aside relativity, since when you’re moving near, at, or beyond the speed of light, you experience time differently (see: interstellar), also gravity can affect this, and other factors. But somehow, they just side-shuffle from the whole time thing and just focus on the drama of it all. Viewers are too enthralled with the spectacle, not realizing that these Romans or boleans, or Klingons, or cardassians, or whatever, probably have a completely different idea of how much time their version of “one hour” or “one day” is.
It’s fascinating and frustrating.
I love it and hate it all at the same time.
Time sucks. It’s never correct, often ignored, and bluntly, a strange concept that isn’t, IMO, well defined. We have the idea pretty well set up here on earth, based entirely on things happening on and to this planet, but if you take that reference point away, everything collapses.
The proposed time zone is to drift about 1 second every 50 years. I also suspect it wouldn’t really be a time zone in the same sense as the time zones we know - it would just be a standardised calibration reference. Dates and times expressed in “moon time” would probably just be some leap second off of a known Earth time zone, and because it’s mere seconds over centuries, I think the only use of this time zone is to calculate ultra-precise time diffs between two earth datetimes when the observer is on the moon. At least, that’s how I interpret the articles I can find about it.
That’s it, I’m only using epoch from now on, that’s enough of your time zone shenanigans
So, in this case a moon timezone, and more generally a “space timekeeping framework” makes sense because time actually moves at a different speed on the moon, so epoch times wouldn’t actually stay in sync.
If the goal of “time” is to make it easier to reason about simultaneous things, then space makes that way more complicated.
It’s just tricky to condense that into a headline that conveys the point.The concept of “simultaneous” breaks down over relativistic distances too so that’s equally fucked
Except the length of a second is different on the moon because of relativity. So even utc is wrong.
UTC doesn’t become wrong, you can either just accept a different pace of the clock, i.e. earth ppl will be ever so late to a meeting or it’s just a different kind of timezone conversion. Better would be to have a single time based on the reference frame of the center of the galaxy and everyone keep there time relative to that.
just use a time based on light?, like meter is based on the speed fo light in the vaccum, or use atomic based times?, like how long take for the hydrogen atom todo something bla bla bla
That’s actually what’s different on the moon. Relativity and all that means that time itself actually flows differently on the moon than it does on earth.
The actual problem they’re working to solve is around timekeeping and GPS applications in different reference frames, but it’s hard to make a short headline about.
When I first saw the news I was thinking “there’s no way atoms vibrate differently on the moon” but you’re right it’s about perspective and I’ve realized there’s no way I’m smart enough to handle timezones on an interplanetary scale. I can only hope that the difference between earth seconds and moon seconds can be expressed as a consistent ratio.
I will gladly use some programming library invented in the basement of a university powered by coffee, and rage.
It’s well understood math, but it’s “only” relativistic orbital mechanics.
It boils down to a pretty consistent number, but how you get there is related to the weight of the moon, how far it is from earth, and how fast it’s going.
Since the moon is going different speeds at different places in it’s orbit, the number actually changes slightly over the month.They’re just using the average though, since it makes life far easier. We use the average for earth too, since clocks move differently at different altitudes or distances from the equator.
Sure, we can compromise; they can have their own timezone, but it has a constant time value.
const moonTime = DateTime.Utc.MoonTimeAs in, it is perpetually 4:20 PM on the moon?
nice.
Nah dog, its gonna be UTC. End of story.
It’s own timezone? It’ll need it’s own clock. A moon day is about 28 Earth days.
International Fixed Calendar (but beginning the week on Monday) ftw
Shouldn’t the moon have… 24 time zones as well, depending where on the moon you currently are?
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 still think timezones were a mistake, and that they shouldn’t exist period. I have a long thread about this from an earlier post about timezones as well amusingly enough.
As a social construct, I like that I can be anywhere in the world and know that around noon is probably an appropriate time for lunch, etc.
Time is an illusion, lunch time doubly so.
Anyone else keep nearly everything set to UTC?
In the military that’s all we used. It’s called Zulu time in the Army and it makes for coordinating events in multiple time zones fairly easy. I would assume the moon would be the same since there will 100% be a moon base with military.
