Why isn’t this a popular thing?
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.

I can see how someone that doesn’t understand the words would think that.
It’s not every sentence, sheesh. It’s like two of them.

But again, why should most of us waste our time when we’re almost never troubled by time zone changes?
But won’t you think of the poor developers who have to occasionally write software that handles local times?!
(Or the poor international business person who has to coordinate virtual meetings around the globe?!?)
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 of solar noon, 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.
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.”
We should also all work 9am-5pm of course.
Edit: it would be wild because in the USA the shops would open in the middle of the night etc.
Who are you, a service employee? In our country, office workers’ shifts are 7-15 and factory workers’ 6-14, plus 14-22 and 22-6 in two/three-shift operations. The workday opening hours of small businesses are approximately:
- Convenience shops: 6-7 to 18-21 (overwhelmingly run by the Vietnamese minority)
- Pubs: 10-16 to 20-24
- Bakeries: 6 to 15-16
- Clothes stores, jewelry etc.: 8-10 to 16-18 (closest to a “9-5”)
- Hairdressers, massage parlors: by appointment, usually 10-20
People who ever work after 16:00 are a minority.
To be fair, a lot of office jobs (in Prague at least) are 9-17, or 8-16. Unless you meant government offices, which do open earlier with standart 8(7.5)hr shift
CZECH FOUND
You’ve been added to the list. There’s nearly 10 of us, almost enough to keep !prague@feddit.org afloat!
That’s 9:00 - 17:00.
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.
You know who hates time zones the most? Programmers.
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).
With global UTC timezone, then you need to ask, which are your work hours?
Which would be beautiful because you’d instantly gain an intuitive understanding of how that overlaps with your own work hours instead of having to do a conversion.
You’re doing a conversion when you ask that question. My point is, there is no gain, is just converting one system for another that requires the exact work. Then we’ll have tables of “workzones per country” and we need to do the same conversion to setup a meeting.
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.
Base 10/100 is inferior to 12/60 when it comes to splitting.
10 can only be divided by 10,5,2, and 1. 100 only adds 4, 25, and 50 to that.
12 is divisible by 12,6,4,3,2, and 1. 60 adds 5,10,15,20, and 30.
What is time other than measuring the movements of circles and spheres? The rotation of the earth, the revolution around the sun. It makes sense for us to use the same basic 12/60/360 tools we use for circles, degrees. The “metric” measurement of circles is radians, which would require factoring pi into our measurement of time, and that would be way more complicated.
That is correct. We’d gain a few things though. For example I could easily tell how much time passed between 8:47am and 3:22pm without doing all the gymnastics. Or maybe how many days it is until a certain date. As of now that’s just a lot of irregular 30s and 31s and then the last of February and you almost need a look-up table for that with all the extra rules and exceptions.
Main thing I wanted to say, once you decouple time from the timezones, you’re somewhat on the way of making earth’s spin meaningless. You’d end up going to work at 14:50 and returning home at 23:20 anyway (for example). Maybe you’ll advance into a new day randomly while at it. I don’t see how that’s fundamentally different to just working from 250 until 600. And I think I can as easily remember to pick up the kids at 2am or at 100 ticks. Also some calculations wirh the 60 are really annoying. Netflix will show a movie is 155 minutes, it’s now x o clock and do I get to bed at 10:30pm? That’d also be easier with metric. And once I look at kids these days, they don’t know how to read those circular clocks in the first place. So drawing time on a circle might be an arcane, old concept to them, and we don’t need to bother with the circle for much longer…
(There is some sarcasm hidden in these words.)
(Edit: And dividing the circle is another thing. Why not use radians, or better tau? I mean I get that 360 has a lot of divisors. But why do I need to remember that 3/4 of a circle is 270 degrees, why can’t I just say three quarters of the circle? Or store a concept of how much 200 degrees is in my brain if the calculator returns this? I think it’d be far easier if it gave that to me in fractions of the whole circle. I have a rough concept of what 55% and a bit is…)
Maybe it would be easier if the earth would be flat :)
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
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.
Why should the UK get to be the only place with an accurate local time? I don’t want to live on UK time.

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?
Your 9-5 is his 11-4
So does this colleague suddenly have to work 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.
Everyone who works a daylight job would work a daylight job with Universal Time. We exist under Universal Time right now, and yet you (and the majority of other people in the world) work during the day. Nothing would change.
Everyone would work whatever part of the day they work right now, except the numbers would change. And you’d have to learn what numbers mean “get up”, “lunch”, “dinner”, and “sleep” because they won’t be what you’re used to.
The current clock numbers are entirely arbitrary. (And they repeat!) When you were a kid, you had to learn what the hours meant relative to what part of the day it was. Under universal time, you would simply relearn that. Children learning it now would never know the difference. They would think local time is weird.
I don’t understand why every time this conversation comes up, there are always people who think that it means you’d have to change when you sleep, live, and work relative to the sun. I just don’t get it. It just seems like such an odd conclusion to me.
Because we like midnight to happen at night, and noon to happen during the day
And you’d still have to adjust to local time anyway! Travel three timezones and now noon is at 9 instead of 12. Your alarm to wake up at 6, now needs to be at 3.
Literally sounds a lot worse. Imagine telling your friend in Europe from the USA “ugh, I have to get up at 10 AM for work!” And the european responds with “10am is pretty late!”
Why would you want to get up every day at 6 am from three time zones over?
Sunrise at 06:00 UTC in one timezone would occur at 03:00 UTC three timezones over, I mean. The relationship between standard time and local, solar noon based time (sunrise, noon, sunset, midnight) is going to have a flexing relationship across different places on Earth. So if you’re travelling or even communicating across timezones, you haven’t fixed anything by using UTC since daily activities (sleep, meals, etc.) are still correlated to when the sun is up or not. Timezones communicates that daily relationship with time pretty effectively without having to do a lot of thought about it all the time.
Sunrise at 06:00 UTC in one timezone would occur at 03:00 UTC three timezones over
Right, but I wouldn’t want to keep my daily routine aligned to a different time zone than where I am.
So if you’re travelling or even communicating across timezones, you haven’t fixed anything by using UTC since daily activities (sleep, meals, etc.) are still correlated to when the sun is up or not
Exactly. So why would I want to adjust my alarm to 3am after travelling 3 time zones? I only care about relating the time between two zones for real-time communication with people in the other zone. And I’m not getting up at 3am for them.
I don’t understand what you’re asking here. I’m saying if you kept UTC in every place on earth, you’d still have to relate those hours to a solar based local time. If you wake up at 6UTC in London and then travel to Moscow, the sun in Moscow would rise 3 hours earlier (guessing, not sure exactly what time time difference is). So if Moscow was also keeping UTC, they would set their alarms for 3UTC to wake up with the sun. If you travel to Moscow, you’d wake up at 3UTC with the sun, which is the equivalent of 3am London time, but is around sunrise locally. This is just how time zones work, so I have no idea where the confusion is.
I mistook your original comment about the alarm clock. I wasn’t reading it as the clocks in all timezones being set to UTC and rather that you wanted to keep your daily routine aligned with the daily solar cycle of the time zone you left.
Ahh, no! I was agreeing with the top comment that using UTC everywhere would cause more problems. Glad we’re on the same page now!
stop calling it “midday” and “midnight” and it works
Not very convenient if a date change happens during your typical workday and that your meeting is from Monday 23:00 o’clock until Tuesday 1:00 o’clock. I mean, sure, we could deal with it, but locally it only adds new complexity.
Sure, you could talk with anyone in the world and agree on a time without misunderstandings, but as soon as you want to know if people in the other country are even awake at that time, or if it’s during business hours, you need to do the same calculations as before and need to look up how many hours the schedule is shifted in that country, similar to before.
My Anki deck (flashcards app) would like to know when it’s the next day. It now uses a standard (configurable) value worldwide (4:00 o’clock, to allow for late nights). If we used UTC everywhere, a standard value wouldn’t make any sense, and you would have to know the local offset, and change it when you are traveling.
Taking about traveling: instead of just changing the time zone on your devices and be done with it, you need to look up what time you should go to sleep and wake up and at what time the stores open to fit the local schedule and none of the hours that you’re used to would make any sense. Let’s have dinner at 19:00 o’clock. No, wait, that’s in the early morning here.
We already have UTC as a standard reference, and we don’t need to adopt it for local time, as long as the offset is clear when communicating across borders. Digital calendars already take time zones into account, so when I’m inviting people from overseas, they know at what time in their local timezone the meeting starts.
The issue is not the time zones, but the fact that we live on a sphere revolving around a star and that our biological system likes to be awake when it’s light outside.
This is exactly right. People don’t wan to change, even if the new way is demonstrably superior. Look at the adoption of the Metric system in England and the (almost) adoption in the US.
UTC isn’t even demonstrably superior.
and the (almost) adoption in the US.
For example:
-
1 dry pint is exactly 107521/92400 liquid pints.
-
1 liquid pint is exactly 231/8 cubic inches.
-
We formally defined the inch in terms of the metric system in the 1950s as being precisely 2.54 centimeters.
Thus making the bushel exactly 220244188543/6250000 cubic centimeters.¹
¹ Unless you’re talking about an oat bushel, a barley bushel, a wheat bushel, or a few other exceptions.
Well, that is neat. When using metric and celsius:
- 1 kilometer is 1.000 meters.
- 1 square meter of water weighs exactly 1 tonne. (1.000 kilo also known as a kilokilo)
- The vastly superior metric dozen is exactly 10.
- Water freezes at exactly 0 degrees.
- 1 meter of water takes exactly 100 minutes - a metric hour - to completely evaporate when heated to 100 degrees. Doing so requires exactly 1 kilowatt of power.
Your last point is wrong, at least as you have stated it. Evaporation time is based on surface area, and the required power is based on volume, but you expressed the amount of water as a length.
Still, metric is way better.
