Well the solution to our “not enough bits” problem has been generally available for 20 years. Signed bigint time would cover from the Permian Period until 290 million years from now, down to ms precision. That ought to be good enough for most use cases.

Maybe it would be easier if the earth would be flat :)

because we sleep at night and are active during the day, and so we need to track that in a way that is universal. if i mention 12:00, people understand that it is noon where i am, and if i mention 22:00, they know it’s bedtime.

the whole point of time zones is to have time cohesion in a wider region within margin of error, so people on the far east and far west of a time zone are close enough to solar noon at 12:00. you can take a train to a neighbouring city without having to worry about needing to adjust your timekeeping devices by a few minutes.

to put your scenario into perspective, china has already done what you suggested on a smaller scale: the entire country is on UTC+8 for the sake of “unity” and “national cohesion”. beijing loves it; 12:00 is still noon there! except it ain’t in xinjiang and tibet. xinjiang has its own unofficial xinjiang time zone of UTC+6, and so people have to specify which time zone they’re talking about and convert times between the two time zones in conversation because the uyghers use xinjiang time and the han chinese use beijing time, and you can imagine the confusion and also technical issues that has arisen from that.

imagine that, but 12 times worse. no thanks, i’ll do the simple math of converting time zones if i ever need to communicate internationally.

fuck daylight savings. take that shit out back.

Why should the UK get to be the only place with an accurate local time? I don’t want to live on UK time.

On the other hand, we could refine time zones so they’re continuous instead of discrete chunks. Then every step you take adjusts the time. Would be more “accurate.”

Because “the markets open at 9” is an international standard that everyone can count on. You could stagger it so that one country’s market opens at 10, then another at 12, and so on, but then what if one country chooses a different standard? What if a restaurant picks a different convention than businesses in one area? Time zones are great because once you understand them, you’ll always know how time works locally, anywhere in the world with a single piece of information, it’s a truly successful standard.

There was a time not long before the railroads when time zones didn’t even exist and times were tracked locally. That’s what it was like for most of human history.

Of course we don’t have to behave tomorrow the same way that we behaved yesterday, but on the other hand, the system works fairly well for almost everyone almost all of the time. If we were to switch to what you’re proposing, there would actually have to be a lot of work done to recreate currently existing functionality, because people wouldn’t have any idea when it’s light or dark outside or when businesses are open. Of course we could do all of that. But again, why should most of us waste our time when we’re almost never troubled by time zone changes?

The other point is that although we do have to deal with time zone changes, in reality the situation is much simpler than it was 20 years ago, because a lot of our software is very savvy and automatically converts things for us.

Long discussion here. I feel I’d like to add two things. First: we already do. If you coordinate international video calls or conference live streams, you’ll say it starts 14:00 UTC. That is something we can do and regularly do. Some companies will use the timezone of their headquarters, though.

Furthermore: Once you’re already in the process of changing how time works, don’t do a half-assed job. Go all the way and make it metric. Do away with all the 12/24 and 60s. And make things divisible by 1000.

We should also all work 9am-5pm of course.

That would be shifting from timezone to “workzone” or “noonzone”. At this moment you need to setup a meeting with people, then you ask which is their timezone. With global UTC timezone, then you need to ask, which are your work hours? (workzone).

I work with someone who does 9-5 in the next state, a messily -4 hours away.

They get to work when I have lunch, when I’m waiting on something from them in the afternoon they’re just dealing with morning shit. When their system crashes at 4:50 in the afternoon as usual I’m making dinner.

So does this colleague suddenly have to work 9-5 in +0 time. Or do they keep working real 9-5?

Worst of all, he sees a bit of daylight on the sunrise commute home. Yet I as a +10 would never see the sun.

How do you propose any of this work?

Almost a century ago, the fascist dictator of Spain wanted to appease Hitler and decided to move the timezone from the UK one to the German one. With daylight savings the situation in summer was a bit ridiculous: dark until 9 am and sun until 10 pm, it was very confusing as a tourist to have all the stores to open so late in morning and go out to eat dinner so late

I can’t imagine what kind of mess would be going to Japan as a tourist on UTC+0

This is a surprisingly divisive topic every time I see it or suggest it. I reckon the divisor is “people who use and work across timezones a lot” and “people who don’t”. Fuck I hate timezones.

That would make time more unrelated to the sun, which is pretty important.

It’s because a lot of the way humans go about their life is based on traditions. Getting everybody to switch from a system that already works pretty well is just a hassle.

Examples:

• English spelling is faaar from phonetic and children take longer to learn how to spell than in Spanish for example. (though, cough, enough, plough instead of something like thouğ, koff, enaf and the US plow)
• Metric system adopted globally would streamline a lot of global industries that have no cater to each system.
• Driving right side everywhere. Sweden switched but asking India to switch makes way less sense.
• Date formats. Arguably the best if everyone uses ISO 8601 but nobody does.
