For some reason I thought this was going to be about an alternative to daylight savings time and any suggestion of abolishing that always gets my interest. It's not though, it's about giving the moon its own time zone. Which is about that least exciting moon based news I've ever heard although I'm sure there's interesting technical challenges (which I sincerely hope I never have to deal with).

I can't wait to have to take into consideration the timezone of the moon people when I schedule my zoom meetings in the future. /s

Spare a thought for the future maintainers of liblunar.

FTA: > Clocks run faster on the moon than on Earth, gaining about 56 microseconds each day Unless my maths is wrong isn’t it actually 200 milliseconds per year? It’s not a lot of time, sure. But it seems important to people like scientists. Which, not coincidentally, is probably the most ”practical”…

Yes, you are right. 0.02 seconds; I made a conversion error to ms.

If there's ticks on the moon, we have bigger issues I suppose.

"Ticks...why'd it have to be ticks?" I was hiking in Edgewood Park on the SF Peninsula, and when I got to my car and took off my hat, this big fat tick came running out. He must have been the size of a coffee bean, or it sure looked that way in my moment of fear. Is it true that they grow six times larger on the Moon?

If it's true they can just blow up the Moon for all I care.

'I'll call you tomorrow.' 'Tomorrow clock time or tomorrow after the Sun rises?'

So we'd need to adjust our terminology a bit. I'm sure the world wouldn't end because of that. It's always amusing to me how opponents of the idea of abolishing time zones assume that everything will stay the same, except, well abolishing of time zones. Apparently in the moment we do so, humanity will be become incapable of adjusting even the slightest. It will be impossible to invent a couple of new terms to let peo…

Decoupling day cycle from the sun is quite a big change.

I would be happy if we got rid of timezones, got rid of daylight savings time, and got rid of 12 hour clocks.

I think even if governments around the world abolished time zones, tried to ban their use and forced a universal time, you would still end up with folk implementation of time zones that ends up being worse where people translate the universal time to and from the non-standard local time. You can see some of that behavior here: https://en.wikipedia.org/wiki/Xinjiang_Time

With timezones: * I want to call my friend in Germany. What time is it for her? I guess I'm UTC-7 and she's UTC+1, so she's 8 hours ahead of me. I know that everybody around the world typically wakes up between 6 and 9 AM and goes to sleep between 8 PM and midnight, and she's an early bird, so she should be awake. * They said the meeting was going to be at 8 o'clock, but they are in a different time zone, did they me…

> * If I live too far from the UTC, the day will change in the middle of my working day. My friend said they'd see me on Tuesday. Do they mean the day that had Tuesday at the beginning of it, or the end? What does "Tuesday morning" mean when morning is at the end of the Tuesday? Is "morning" the beginning of the solar day or the beginning of the clock day? The problem there is the lack of specificity, and timezones d…

In the military, there is Zulu (+0 UTC/GMT) and Juliet time ("my" time). Every report with times should always indicate the timezone (whether Z or J or otherwise), e.g. in NYC 2pm would be 1400Y. Any recent/current military folks want to comment?

They mean local lunar time, for coordination between actors on the moon. Lunar day length and even, due to gravity, second length differ from Earth (i.e., time moves at a different speed).

> They mean local lunar time, for coordination between actors on the moon. Lunar day length and even, due to gravity, second length differ from Earth (i.e., time moves at a different speed). These two sentences aren't related to each other. Time moves at a different speed on the moon than it does on Earth. But that only affects interactions between the Earth and the moon. Two actors that are both on the moon are both…

That's basic physics, it surprises me some users seem to not understand how time works even on a forum like HN.

Just use Julian dates. This way you can also get rid of years, months, weeks, ... You only need to change the Julian period every now and then, ie. every 7980 years. See: https://en.wikipedia.org/wiki/Julian_day
