Why don't the whole planet just use UTC+00:00 / Universal Time without time zones?
-
You can't be serious. There's no way we can compare something that spans two hours both ways with something that spans twelve hours.
It spans 4,5 hours one way, and 0,5 hours the other way*
So, it's a big deal.
-
That would make time more unrelated to the sun, which is pretty important.
We could just get used to the fact that in this location 6 PM means noon and in this other location it's 3 PM
It's changing all the time anyway, so time is almost never aligned with the sun.

Americans saying the metric system is dumb while reasoning that its bad because they can't do decimals and fractions properly will never not be funny.
"omg 1/3km is 333.33 metres! it doesnt make any sense!"
1 foot = 0.33 yards? "totally logical, so easy!"
5280 feet in a mile? "wow so simple"
10mm in a cm, 100cm in a m, 1000m in a km? "its impossible to grasp!"
you guys think you're so ahead of the rest of the world, while crashing probes into Mars and not knowing a 1/3 pounder is bigger than a 1/4 pounder, but everyone else easily converting volume to weight to temperature to distance at every order of magnitude are just laughing at you.
To me, claiming imperial system is better than metric comes off just as blind arrogance. Its "american" system thus criticising it is like personally attacking them. At least I cant rationalise it in any other way.
-
We use base 10 because we have 10 unique numerals because we have 10 fingers.
That seems a pretty good reason to me
Seems like a silly reason to me. Base 12 is easier to divide.
-
For the same reason the whole planet does not use the metric system (I'm looking at you america, you old faded superpower).
So how come the rest of the planet besides America hasn't transitioned to a single time zone yet?

Sounds a lot like getting used to time zones. Just get used to it being 3pm there when it's 6pm here

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.
I do use ISO 8601

Yeah, the number on the clock is just a number. Does it matter if it says 12 or 6 or 20?
That said, if we were going to a universal time zone, I would definitely get rid of AM/PM and do 24-hour clock.
-
Here are some reasons told through what-if.
TL;DR:
People like to sleep in the dark generally, and businesses that close are open when more people are awake.You still sleep at night and have businesses open during the day. It's just that the numbers displayed on the clock are different when this happens. Maybe standard business hours are 2-10 or 14-22 instead of 9-17 (I advocate 24-hour clock instead of AM/PM).
-
Because that would be a nightmare. "I'll meet you for lunch at 2AM", "No, I had a huge breakfast yesterday". You would need to relearn the times every time you went to a different place, "oh, right, the restaurants only serve lunch until 10AM" or "Sorry sir, but there's an extra fee for night time services starting 1PM". Those are much more likely day-to-day phrases than scheduling a meeting with someone from another continent. And you don't gain anything by this, because whenever you're communicating across timezones you can simply use UTC as a standard and everyone knows how to convert that to their own time. So there's no good reason and a lot of drawbacks.
Only because we're already familiar with the current way of doing things, though. If we had all been on UTC for our entire lives, it would be a simple matter of getting to a new place, asking when local noon is, and going about our business.
"Hey, when is local noon here?"
"'bout 0330."
"Cool, thanks. Want to get together for drinks tomorrow night? Say, around 1045?"
They're all just numbers. They have no inherent meaning, only what we imbue then with.
It would get a little bit tricky with the date switching over in the middle of the day, of course. In my mind, that's the biggest reason.

The issue (as the link illustrates, but I didn't go into detail) comes with long distance communication. Time zones serve as a rough approximation for 'where is the sun' at a specific place that you want to communicate/trade with and that is a rough approximation for 'when are people/places likely to be awake/open. Without that you Would need to find published hours for people/places and that can be tough.
Replacing time zones isn't impossible of course, but it's definitely not as simple as 'just use UTC+0'. That shifts the inconvenience elsewhere
-
Why isn't this a popular thing?
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.

So every time you deal with somebody in a different location, you can't assume anything about the hours and times you have to ask them or go look it up Even if you have a decent idea where they live because you're not going to know the time disparity of every city out there.

So… like it is already? Ever tried to call someone in a different time zone? It’s fine-ish 1 or maybe 2 hours off, but much beyond that still requires a minimum of research.
-
kind of my point. Trains need accurately measured time in order to run properly.
The proposed change to UTC globally does not change the accuracy of time measurements. I think it’s a terrible idea, but I fail to see how your point here relates.

The cultural relationship with time is more important than its absolute measurement.
This was the statement at the top of this discussion. It values the local concept of what time should be over an objective measurement of what time is.
The proposed change wouldn't cause much of a problem. But the idea under the statement I quoted would.

Fair, thanks for the context

Why exactly is asking for "what time is the local noon" more convenient than asking "what timezone is this"?
How is "local noon is at 2:45" somehow easier to adjust to than "adjust your clock by X hours"? You don't need to relearn every thing like what time breakfast is served when local noon is 08:50.

Your ring up a person, they go "why the fuck are you calling me at 09:45?", sounding really upset. You don't understand why. He's in a place where that means it's the middle of the night and as a local he understands it.
Oooor
He could just say "do you know what time it is here? It's two am!" and you'd understand.

Answer quickly, if noon is 0330 what time is dinner, what is a 9-5 job and what time do you expect to have breakfast. There are lots of adjustments you will need to make, whereas with the current system you know that as a general rule you can expect dinner at around 8, most people to work 9-5, and places to serve breakfast at 8 or 9, so you switch your clock when you arrive and you're done.
If you're a local who never moved timezones z then yeah it makes no difference what the numbers are, you would get used to waking up at 9PM and switching date midway through the day, there might even be 2 different words for tomorrow, one for the next day one for the next date, but the moment you traveled to a different location all of your years of being used to general time where things happen go out the window, it's much more of a hassle than adjusting your clock and assuming times will be mostly similar.
