Why don't the whole planet just use UTC+00:00 / Universal Time without time zones?
-
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.

TL:DR -> https://thelemmy.club/comment/19143233
Examples:
-
The year doesn't start at the shortest day (Persian calendar is better in that regard).
-
month length is not evenly distributed. Why is February shorter?
-
time is almost never power of 10: there is 12, 60, 24
-
time zones are used to follow alliances: see al the nations that went to CET after fall of URSS
-
you can easily estimate your local time by looking at the sun
-
Holidays tend to happen on the same approximate dates even when major cultural changes happen. See how Christianity took over a lot of things from Romans.

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.ΒΉ

- 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.

Same reason some people use miles instead of kilometers, or that most people use Windows even if they hate it.
Inertia is a powerful force.

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.

Because timezones were a result of town specific clocks, which were a result of people liking certain hours happening generally in line with where the sun is, like "noon" which still technically refers to when the sun is at its highest point.
Well, the result of railroads needing to standardize time tables.
Prior to that, towns had their own local time, and often it was approximate at best, based on a guy looking at a shadow and keeping time with inaccurate tools.
Imagine trying to explain to the people of Bumblefuck, IA that the train departs Nowheresville, IA at 10:30, and is a 30 minute trip, but the train arrives in Bumblefuck at 10:52 because the town clock is the one guy that winds his watch every day.

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.
-
Time zones were the result of railroads getting towns to abandon their town specific clocks because of railroads.
This really fails to acknowledge the hodegpode, anything goes chaos that was towns choosing their own noon based around someone with a watch and a bell looking at the shadow on a stick a few times a year.
Sometimes standardization isn't simply a terror induced by capitalism, and has accrual benefits.

Longyearbyen experiences midnight sun from between 18 April and 24 August (128 days), polar night from 27 October to 15 February (111 days), and civil polar night from 13 November to 29 January. However, due to shading from mountains, the sun is not visible in Longyearbyen until around 8 March.

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.

It wasn't a hodgepodge; it was a system designed to the requirements of the day. Every town setting their own clocks to the local high noon wasn't a bad idea for a while. Hell, the ability to transfer the knowledge of time from another part of the world only came about a few generations before.
It wasn't until the railroads started operating where it became important for different cities to have the same time down to the minute. Until then, local noon worked well enough.

I see this argument all the time. Forget all the tradition, "people like noon near solar noon", all that.
Date changes mid day some places and not others would be a nightmare for so many things.
What're you doing on the Tuesday half of June 15/16th?

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.

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.

βοΈDo you also want the day to change from Sunday to Monday in the middle of your Sunday morning? Or do we change days at different hours everywhere?

The cultural relationship with time is more important than its absolute measurement.
Tell that to the trains.
