And instead changing the time work and other things happens depending on where you are. Would be easier to arrange meetings across the globe. Same thing applies to summertime. You may start work earlier if you want, but dont change the clocks!
So You Want To Abolish Time Zones
In a nutshell:
Before abolishing time zones:
I want to call my Uncle Steve in Melbourne. What time is it there?
Google tells me it is currently 4:25am there.
It’s probably best not to call right now.
After abolishing time zones:
I want to call my Uncle Steve in Melbourne. What time is it there?
It is 04:25 (“four twenty-five”) there, same as it is here.
Does that mean I can call him?
I don’t know.

What time zone is that minute in?!

Yeah but in your example, you wouldn’t need to look anything up either. You’re presumably very familiar with the offset of your time to their time? You’d also become familiar with their “universal time” versus your time. You’d just know what hours they’d be awake and asleep because you will have done the translation a few times.
In addition, I - personally - would find it easier to memorize times in a single system: e.g. remembering that people in China are awake from 9pm to 8am is easier for me to remember. I typically already do this in my own head. I’ll convert times to my own local time and then memorize that. Do other people not do that? I find it much easier to look at my own clock and know if I can reach out to someone internationally.

It’s not that different. But you’re mentally mapping a UTC offset to your local time as well? Doesn’t that mean you have to do something like:
- Does this time work for me? (Map offset to my time)
- Does this time work for them? (Map offset to their time)
Genuine question here. Seems like you’re doing twice the time-conversions when using UTC.
Removed by mod
Whether you realise it or not, there are two hours you are using here. Your local time that you suppose is automatically converted in your brain, and the international time that you can already use and is called UTC.
Learn to use UTC, problem solved.
Why do you want to create problems when there is a solution already?
deleted by creator
That time means nothing anymore. Time is something real, not a mere number that’s irrelevant to reality. Midday is the middle of the day and the zenith of the sun, or close enough. Midnight is the middle of the night. Etc. It doesn’t need to be exact, but it needs to mean something. In France for example 4PM is the name of the snack you eat that this time.

Language is also a social construct.
So, let’s put it this way. Let’s say you have this nonsensical idea of a unique timezone for the planet. We’ll base it on UTC for simplicity.
You are in new York. It’s 1000. For you in new York, it’s the middle of night. You’ll wake up in a few hours. Your day usually goes about with wake up and work around 1400, lunch around 1800, end of work around 2200, sleep around 600. You can live you life with that. It’s merely a social construct. It’s completely stupid as a construct because it’s not setup for your actual day. The 0 means absolutely nothing. The 12 and the 24 neither. Why have a 24 hours clock for this? But a decimal clock would do nothing more.
Now you need to work with someone in the UK. Can you talk to him right now? Who knows? You need to ask Internet about the time delay between where you live and where he lives. You learn it’s +6. Or -6. Who cares. Now you juggle with 2 times at your work: your usual one, and your colleague one. Congrats, you made a timezone again. When you need to know when he starts work, you do the maths : 1400-600=800. He must starts at 800, unless there’s some cultural differences.
Now what you call 1800 is called 1200 for him. You made the same concept, the lunch time, have a different name depending on where you live, and that is after the translation.
Why even have a time at this point. It’s more confusing than anything. Let’s just have minutes.
You’ll have wakeup +200 for example. At wakeup +400, it’s midday. Midday +400 is the break. Break+400 is dinner. Dinner +400 is sleepy time. Now that would be much more sensible than your unified clock. There would still be problem with timezones interaction.
But there’s nothing to do about timezones. It’s and effect of the spherical earth and general relativity. In physics, there is a clock for each and every position, and a delay between each. Most of the time it doesn’t matter, so you use your local time. But when it does, you do timezones. Because that’s how the world physically works.

Timezones exist because that’s how time make sense everywhere.
Je joke works because the earth is a sphere btw. It’s not a joke, it’s a fact. That’s the whole point.
No, timezones don’t make sense everywhere, you clearly have not lived on the edge of timezones where the shift from what would be local time is notable.
In one of these stories you used Google and in the other you didn’t. Both of these problems are solveable with Google
We could all just cover our windows, take Vitamin D supplements and actually all live on the UTC timezone.
And let the brits enjoy UTC+0 like nothing happened while the rest of the word scrambles to adapt to the new time system? This is tyranny! I demand a new system where my region is the one with UTC+0 instead!
Have UTC+0 run horizontally, instead.
And increase its width to run from +80° to -80°.
Squeeze the rest of the timezones into the polesNo! In summer time we’d be a whole hour out of our natural time! It would be too much to handle.
You still need to convert in your head to “decide if usually awake at this time”. This solves nothing. Plus what if they’re somewhere unfamiliar on a trip?
Meanwhile stuff like world time buddy or other locations on clocks are very accessible tools
The joke is that the whole world could go to sleep/wake up/work at the exact same time, day or night.
I lived in a tiny apartment with a streetlamp just outside my only window. Even with blackout curtains that room had no day/night cycle. I’m still trying to get back on a normal day/night cycle, fifteen years later.
So, that’s another method you could try.
Google tells me people are usually awake at 20:25 there.
Problem solved. This actually makes it problem simpler. With different time zones:
- Get local time.
- Convert to target time.
- Decide if your uncle is usually awake at the target time.
With one time zone:
- Get time.
- Decide if your uncle is usually awake at that time.
Exactly, it always requires knowing your uncles habits.
No shit, so no difference to the current situation.
I am too late. I knew this would be the top post, even though the arguments brought forth in the blog post are utterly stupid. I would even go so far as to say their arguments are presented in bad faith, because I refuse to believe the author actually thinks that’s how it would go. (They have some seriously awesome posts, I most highly recommend https://qntm.org/mmacevedo)
With time zones:
you Google what the timzone offset is (aka at which point in your local timezone the sun rises over there). Considering this sunrise time you then have to make a judgement if your uncle would be awake now.Without times zones: you Google at which time the sun rises over there. Considering this sunrise time you then have to make a judgement if your uncle would be awake now.
It’s literally the same process.
Ah yes, sunrise. That things that never ever changes depending on the time of year or location on the planet. Very dependable and memorizable thing, the sunrise.
Yeah, which makes the points, it’s non trivial to know when to contact people with timezones anyways. The time zone only adds more complexity.
I think the point is that people’s routine isn’t tied to sunrise. For example, in the summertime I start work about 4 hours after sunrise, and in the winter I start work 20mins after sunrise. The difference would actually be more dramatic without daylight savings With timezones and modern internet you don’t need to look up the offset at all, you just look up the current time in that zone and decide if that’s an appropriate time to call. Speaking as someone who deals with timezones a fair bit, both in work and personal life. And as someone who understands the headache of dealing with them in international computer systems, the time zone system is a very nice compromise. Though daylight savings need to die
If your start time has a 4 hour swing, how could you just look up your local time and make a choice to call?
Very dependable and memorizable thing, the sunrise.
Uh, yeah? Because it defines your circadian rhythm?
Ah yes, clock time. That things that never ever changes depending on the time of year or location on the planet. Very dependable and memorizable thing, the clock time.
The arguments are exactly the same. It basically boils down to the philosophy if you want the daily life to be controlled by clocks or by the natural sleep/wake cycle of the body.
Some prefer by the clock, because it provides a fixed constant, even if it may run counter to our very nature. You very well may prefer that. Others argue for a more natural sleep cycle, especially when it comes to school for example. Complaints about work starting too early are not exactly rare either.Some prefer by the clock, because it provides a fixed constant
Huh, you know what? I think you’re right.

Just add 11 to utc.
No harder than having different times in different places.
Just coordinate via asynchronous communication to schedule a time. It’s not 1935.
You: “hey uncle text me when it would be a good time to have a call”
6 hours later
Uncle: “hey i just got up, lets have a call at 4:50”
You: “thats a bid late for me, im in bed by 4:00, what about 3:30?”
Uncle: “sure sounds great”
No one needed to know anything about when people wake up, where on earth they live, etc.
We do, it’s UTC
You mean like UTC? That thing we already have?
Yeah, what if we had that… but different… but the same?
Like the Good Place’s plan to make larger mini doughnuts that weren’t just regular doughnuts.
It’s a cool idea, but then you lose the local representation of the daylight cycle, which just complicates things again as you try to schedule things with people in other countries without knowing if it’s their bedtime or not.
I play games with international friends and work with international colleagues, so I have my fair share of troubles with time zones. If anything, abolishing daylight savings worldwide would yield much better results.
On a side note, when scheduling events on Discord, I like to add in a unix timestamp that shows everybody their local time. Quite convenient!

True, but time zones offer a good compromise between solar time and globally-synchronized time.
Having 12pm noon be approximately when the sun is highest in the sky is better than not at all, and still gives some form of regional cohesion in terms of timekeeping.
There are pretty extreme examples, of course; China is one entire UTC+8 time zone, and that means Tibet is still dark when Shanghai is wide awake, which is dumb, and as annoying as the US’s 4 time zones is (not counting Alaska and Hawaii), it still makes regional sense.
Fuck daylight savings time.
We cant get Americans to use metric…
One big argument I keep hearing is that it would be too expensive.
It’s honestly not that bad. The estimated cost is around $350 million. Now, that might sound like a lot but when you take into account that it’s about $1 per person it doesn’t seem so bad.
Now, if you consider the military budget of $480 Billion per year it seems even smaller.
It would take approximately 0.07% of the 2024 military budget to switch to metric.I imagine almost a bigger issue than the cost would be the… what’s the American equivalent of a Gammon?.. you know, those people that wouldn’t change to Metric if their life depended on it. Four rods to the hogshead was good enough for their grandpappy and no filthy pinko liberal commie will get them to change. The ones that still don’t wear seatbelts unless a cop is watching.
It’s not cost, it’s just apathy. For most people it would take a while to learn, especially since after school you’re not really measuring that much in most jobs.
Step 1. Make all food packaging list both for a few years. That easy, just put it out there so it starts sinking in slowly.
I mean why?
You could always start switching over then give up half way through. Then you’d be like your Grandpa England.
Doing this would lose a sense of work vs home time for people. I have some coworkers on the other side of the world, I look at their time and know they shouldn’t be online anymore. I tell them things like “Go be with your family” or “Must be sleepy considering how late it is for you”.
It gives me a sense of humanity to know if it’s 8pm their time, it’s way too late for them to be working. I’m sure I could adjust if we all used UTC but it would be so stupid to change.
Also imagine hours for businesses all sounding weird as heck lol.
I tell them things like “Go be with your family” or “Must be sleepy considering how late it is for you”.
I’m glad I’m not the only one who does this sort of thing. I also have to scold some junior colleagues about working on their weekends from time to time. Spending all your time working is just a recipe for loneliness and burnout - I know from experience so, try to nudge others away from it.
You’ll basically have timezones either way, there’s just two ways of doing it.
If we all used UTC, then businesses would need to change what time they opened depending on their location. Ex: Best Buy opening at 12 noon on the US west coast, and 3pm on the east coast. Locations inbetween would have different opening times. So we would get the noon zone, 1pm zone, 2pm zone, and 3pm zone. All nation wide businesses with standard open/close times would effectively follow the same pattern, and it would be best if they all coordinated on where those zones occured. So then we would get new timezones, they’d just be slightly different in how they functioned.
Yes, the main question is picking between:
- The time numbers are the same around the world, but schedules are shifted.
- The time numbers are shifted, but schedules are roughly the same.
Personally I think 1 is more valuable because being able to easily and reliably talk about time seems more useful than being able to have my phone time show a number that lets me guess schedules when visiting a place.
I still don’t get why this is better. You know that 2am people are in bed. No matter where in the world.
We do, it’s called Universal Coordinated Time. The time is now 00:37 UTC, or 16:37 Pacific Daylight Savings Time.
People that proposes to replace local timezones with global UTC must be living in europe where it doesn’t impact them much if we do abolish the timezone. Now consider people that lives in the other side of the planet. Most people are active during the day, yet for them, the day will end right in the afternoon under the new system. So you tell your friend “hey, let’s meet tomorrow”, then your friend would be like “do you mean this afternoon, or in the morning next day?”. No way people living in the asia pacific would accept this without military intervension.
I think they mean concepts like morning and evening, or day and night would remain. The difference would be that in London, midnight would be 12:00am, but in San Fransisco, midnight would be… 16:00 / 4:00pm. Each timezone would have to adjust the numbers, in the same way the southern hemisphere considers January to be in the summer.
isn’t that just timezones with extra steps?
That’s usually the case.
I live and work on London time. If I want to have a phonecall with someone in the Philippines, I have to be mindful that 9am for me is 5pm for them, so I’ll need to make the effort to start early to catch them while they’re still at work.
Without timezones: If I want to have a phonecall with someone in the Philippines, I have to be mindful that their working day is 1am to 9am, so I’ll need to make the effort to start early to catch them while they’re still at work.
I’ll still need to lookup when their working day is, I’ll still have to adjust/account for it, and I’ll still have to get up early / start work early to make that call. Getting rid of timezones doesn’t get rid of that +8 or the affects of that +8, it just renames how we communicate it.
I think the compromise would be the country/region that proposes global time should get the +12h offset. If the benefit really outweigh the pain for them, then they can deal with such a large offset themselves and spare the rest of the world from the brunt of the pain.
nah, a 12-hour offset is boring and easy to deal with. give them a 6-hour offset.
12h offset is where it causes the maximum confusion to society because the date changes right in the middle of the day. In our personal and professional live, we never considered the date can change right in the middle of the day, causing wide variety of minor inconvenience in our daily life. Some examples of minor inconveniences:
- Celebrating new year at noon. No more firework shows (could be good for the environment?).
- Is today your friend’s birthday yet? Or is it in the afternoon?
- should we celebrate christmas on 24th-25th or 25th-26th? Will Santa sneaks into our house at noon?
- and possibly more minor inconveniences…
must be living in europe
This is a very dismissive argument. I live in a time zone where the day number would roll over during my waking day. But I still think that it would be better overall. (But not worth the switching costs.)
“do you mean this afternoon, or in the morning next day?”
It takes very little imagination to realize that this would not be an issue. “Tomorrow” would almost certainly be interpreted as roughly the next daylight period. This issue already exists as people are often up at midnight and somehow we don’t get confused when people say “I’ll see you tomorrow” at 23:55. We know that they don’t mean in 5min. This is just a source of jokes, but no one gets confused.
The real issue would be things like “want to meet on wednesday” if there is a transition during working hours or “want to go out for dinner on the 17th” if the day transition happens near dinner time. I think this would be the hardest part to adapt to, but language is a flexible thing and I doubt it would take long for it to adapt.
I still think the people that would benefit the most from this change are europeans. They are mostly borderless and often works across the member countries than spans 7 timezones, centered roughly around the utc. It’s all benefits with very little downsides.
It takes very little imagination to realize that this would not be an issue.
There are a whole loads of minor annoyances related to this, most of them would vary depending on the local culture. In addition to that, not all countries are sufficiently globalized to realize the benefits of universal time, especially 3rd world countries. People living in those countries will experiences all the drawback with none of the benefits in their daily live.
It takes very little imagination to realize that this would not be an issue. “Tomorrow” would almost certainly be interpreted as roughly the next daylight period.
So when someone is doing this international meeting stuff they have to be very careful about saying “let’s look at this tomorrow” because in various places that can mean different things depending on when each person’s night is.
For synchronizing of things like work and school we’d still end up with zones all using the same local hours (the day goes from 4:00 to 4:00 to e.g.) so we’d still end up with timezones there…
All of the clocks around the world would read the same, sure, but now you have no idea what part of the day 4:00 is somewhere else. You’d end up doing almost the same math as we do now by offsetting their time from yours so you could understand it (4:00 is the same as my 13:00 for e.g. so it’s one hour past noon over there) but now we lose the shared understanding of which numbers correspond to which times of day. This means you’d be having to mentally convert all their new times of day to the clock time instead of having intuitive sense of their meaning.
Instead of seeing the local time is 12:00 and immediately knowing it’s noon, now you’d look up what time their day started and see how many hours it’s been since then (12, so it’s noon there) and that offset is how you’d need to think of it and already what clocks show now…
Pilots already do this. Everything in aviation is “ZULU” time. In computers, we call it UTC or +0000. It actually works really well because we cross time zones so easily.
I would totally be in favor of switching to a universal time zone. But inertia is hard to overcome. Most people don’t change time zones very often as they’re usually far from population centers and people know that when they take a trip, that’s when the time zone will change so for most it’s not a daily concern and getting used to a new time zone model would be annoying. When you tell people about the US state of Indiana, they really start to change their minds, that place is fucked up.
Hint: Reykjavik, Iceland is a major city that uses UTC always, no Daylight Savings Time there. I always keep my second time zone on my watch and phone set to that.
Humans, generally, like to be awake when the sun is visible and asleep when it isn’t. The way we structure our thinking about time, morning, noon, evening, night, are based on the position of the sun.
The single time zone thing sounds appealing until Germans have to be up at 2 AM to speak with their bosses in NYC as that’s a financial power center and thus gets to dictate the meeting times
That is already the case in multinational companies. The problem of daytime here nighttime there but we need to meet is the same no matter what numbers their respective timepieces say.
Perhaps the answer is to reform the concept of the meeting to exist in a far less useful way. Meetings should be a series of prerecorded messages sent via email and played like a correspondence game of Chess.
This would be incredibly inefficient and annoying and perhaps be a catalyst to finally make the weekly update calls a goddamn email that just reads “nothing to report this week, still on schedule to meet Q2 goals” and I can finally get back to smoking weed and ignoring my work phone until 11 AM (sorry, 0635 Neo Standard Time) when I feel like making someone else more money than I’ll ever own.

It can be, yes, usually people attempt to be accommodating. I have a regular 8 AM meeting to collaborate with foreign colleagues for which it’s a 4 PM meeting. Neither of us are happy about it, but that’s compromise.
I think a universal timezone would end up exacerbating the issue of some areas deferring to the ideal time of wealthier areas

-
necessitates significant changes to the way in which normal people talk about time
-
convolutes timetables, where present

means “days” are no longer the same as “days”
-
complicates both secular and religious law
-
is a staggering inconvenience for a minimum of five billion people
-
makes it near-impossible to reason about time in other parts of the world

does not mean everybody gets up at the same time, goes to work at the same time, or goes to bed at the same time

Yes. This is true.

Of course it is simpler. You have just removed a huge source of complexity. It still isn’t simple because people will still live their life at different times. But it is simpler.
means “days” are no longer the same as “days”
Who gets to pick when “noon” is when the sun is usually above their head? Let’s assume Greenwich for posterity sake. That means a bunch of the world will spend most of their “daytime” in traditionally nighttime hours. Thus spending your day (time when the sun is up) and your day (the time when you do your work) will not intuitively mean the same thing
complicates both secular and religious law
Islam requires regular prayer in the direction of mecca and plenty of nations have Islamic law. At a minimum they’d have to rewrite those laws, at most it’d cause a literal schism

“We changed how clocks work for almost everyone on the planet to make some nerds’ lives easier. Please go change your planners, clocks, schedules, applications, signs, etc to adjust”
makes it near-impossible to reason about time in other parts of the world
In most of the world, you can reasonably assume the sun goes up around 7 am and sets around 7. Obviously that changes but you can pretty reasonably assume when people will be around and doing stuff by looking at their time. In this new system you’ll need to figure out what times people do most of their activities based off of geological segments of the planet and checking what their “daytime” is. Which is already a problem timezones address
is not simpler at all
On a base level maybe, but after fixing all the other problems it causes the resulting system would likely be just as if not more complicated than our current time system
That means a bunch of the world will spend most of their “daytime” in traditionally nighttime hours
No, no one would do this. You would continue living your life when the sun is up, the number on the clock would just be different.
Islam requires regular prayer in the direction of mecca and plenty of nations have Islamic law.
So just continue doing this based on the previous schedule? Many religions still celebrate holidays based on alternate calendars and many holidays have strange rules for when they occur. This seems like an incredibly minor issue to me?
We changed how clocks work
Yeah, I agree that the change would be so painful that it isn’t worth it. I am just arguing that I think the end result would be better. Not much better, but better.
you can pretty reasonably assume when people will be around and doing stuff by looking at their time
This seems like a very artificial problem. When will you know their time previously but not their location or relative time of day. You will still know what people are doing. Just because you add the magic number based on their location in the world before consulting their schedule instead of after doesn’t change anything. This only seems like a problem if you were magically teleported to another location underground and only have access to a clock.
I am just arguing that I think the end result would be better. Not much better, but better.
It would be better for whichever countries near the 0 offset (eu if using utc), but massive downgrade for no real benefit for countries near +12h offset (asia pacific). This will be seen as another instance of the west flexing their global power and will take generations to adapt. But if the offset were reversed (asia pacific at 0, the west at +12h) things would go much smoother there.
I think it would be better everywhere. It may be slightly easier if your noon is close to solar noon but really other than Europe and Africa everyone would be in the same boat of having the day number roll over sometime during their waking day. This would probably be the biggest downside but seems like something that language would adapt to quickly. I live at -5 so my day would roll over at 19:00 solar time. So it isn’t like my location is immune to the day rollover issue.
“it’s 2 everywhere, why aren’t you awake?”
-
It would make checking the meeting time a little easier, but make scheduling it way way harder. When scheduling a meeting I want to try to make it reasonable for everyone in the meeting and without time zones I’d have to look up a unique table of when daytime is for every location. That sounds so much worse to me than having a standardized time offset where reasonable working hours are pretty consistently defined. And the main time where I need to check time zones are at scheduling time anyways. When it comes to checking the meeting time everything I use already automatically converts the time to my local time.
We already have it: it’s called UTC. You should read about it probably, instead of asking the whole fucking world to change its uses for your convenience, shouldn’t you?
This response was pointlessly aggressive.
My guy, instead of being condescending for no reason, perhaps you should take the time to actually understand OP’s question.
OP is asking about why the world doesn’t unite under one time zone (UTC+0, UTC-5, UTC+8), not time standard (UTC, TAI, GPST). The hypothetical scenario would be that midnight in the UK would be morning in Japan and evening in the US, but still considered “12 AM” by everyone in those countries, with the hope that it simplifies time coordination across the globe without having to calculate the hour offsets.
I hope you learn to be better, especially in a community called “No Stupid Questions”.
I understand the question very well, it was asked a week or two ago.
This doesn’t simplify anything for anyone because then time would mean nothing. Because of this people would not use this system anyway.
Then please use that as your answer instead of taking such a needlessly aggressive and rude stance in your comment.
