We already have that for technology to use - the unix timestamp.

A unix timestamp is an offset to a UTC date, not a timezone. But fair enough, there is UTC. It's not used by default however, except by scientists and programmers maybe.

Maybe I’m missing something. What do you think the benefits would be?

Removing ambiguity from casual language. Currently when you state a time you are almost always implying your local timezone applies, which might be unknown information to the recipient, especially with written sources like these comments here. With everybody using the same timezone instead you would always make an unambiguous statement about the specific time by default.

What would happen on people that live in UTC+12:00 ? When your friend say “lets meet on Tuesday”, which Tuesday it is (because the day changes at noon)?

Given how +12 is at the front of the "date wave" currently they would probably take it to mean the Monday/Tuesday noon.

People will resist such majorly inconvenience changes unless the benefit of switching is clear for them. Forcing unpopular changes will guarantee people using unofficial timezone which cause even more confusion down the line.

Yeah fair. To me the benefit is clear, there is no good rhyme or reason to timezones as a totality, we should come up with a better system. A straightforward approach like using UTC offsets seems best.

They just gave an example though of people who made up their own timezone because the official one was bad.

Yeah, and in reply I argued that they did this out of not wanting to change their habit of associating 12 o'clock with noon. Which is in my opinion an understandable impulse but not a good reason to preserve the status quo.

These systems exist for people

Yeah fair, I'm aware I'm toeing unpopular opinion territory here.

and if no one other than programmers wants to do the internal calculus of “The sun is setting and they’re a quarter of the earths rotation Eastward, so that means they’re probably in bed” every time you want to call someone, then we shouldn’t make the standard that way.

But the standard is like that right now, worse even with DST and other complexities.

Right now you just look up the timezone in their profile and send it at 9:00, but without timezones, you need a “database of regional conventions for coordinating business hours”, which is just a worse way of having timezones.

Well no you need an offset. Like the user has set +8:30 as their offset, so send the notification at 00:30 UTC. That's not worse than having timezones, that's having timezones but simpler.

Timezones exist because they have a purpose.

Yeah, and some of those purposes are bonkers.

It’s like abolishing everything except latin1 because Unicode is a pain.

More like getting everyone to use Unicode, but whatever. Like I said I see why it would be unpopular to the point of being unenforceable, but that doesn't mean an unambiguous way of communicating time as the default would be entirely undesirable.

Well the essay has a lot to discuss, part of which is already (or will be) addressed up and down thread, so towards your TL;DR:

Yes of course, I'm not suggesting to disrupt circadian rhythms. And yes, lookup tables for solar days will always be required, but I would argue this is an inherent complexity to how we measure time in relation to our behavioural patterns and environment. However doing that by using variously large timezones that do not quite match solar days at their edges anyway, with a lot of them changing their offsets by an hour for half the year, and some of them using half-hour offsets throughout the year, that is complexity added for administrative reasons which are partly obsolete and largely irrelevant to the question off what would benefit humanity as a whole the most.

If everybody were to use one single timezone you would memorise your relative offset to noon/midnight pretty fast. Like it's one number to remember, e.g. where you are 4:40am is noon, 4:40pm is midnight, your offset is -7:20. Having those times be (roughly) 12 (for half the year) is just tradition and something we have every child learn. We could teach them about solar offsets just as well. It's not even really more complex, arguably much less so since you remove the need to confuse them with the chaos that global timezones have grown to be historically.

Oh don't get me wrong, I see how it makes sense. I'm just saying that 1) it is arbitrary nonetheless and 2) it doesn't outweigh the benefits that could be gained by using a single global timezone. Incidence angle of solar radiation is hardly something most people need or even want to track beyond a certain degree (dawn, noon, dusk, midnight), and the times that would coincide with at your latitude and longitude can be easily learned.

people has this urge to associate 12pm to noon and 12am to midnight

Yeah but that is exactly what I mean with habitual. It's a learned association of questionable utility. It can be unlearned and replaced with 0400 is noon or 1600 is noon based on your longitude just as well. Dawn and dusk are dependent on latitude and have to be learned for anything not smack-dab on the equator anyway.

I can see why that would be inconvenient to people, but I would maintain that is only so due to them clinging to a habit.

The fact that you give a preference to change something here which you give as an example for something that shouldn't be changed because it would be problematic is deeply ironic to me.

Also, again, I don't really see the problem with changing the date in the middle of the day. It's virtually the same as changing it at 00:00 or 04:00, you change the date once every 24 hours. Right now you have a situation where one persons 3rd of the month could be another persons 2nd or 4th, depending on where on the globe they are. That's not really ideal either, especially for that call scheduling example by the GP.

Cool, so sunrise is at 8 PM now.

And the problem with that is... ?

Or maybe there’s just no consistent relationship between what a clock on the East and West coast of America say, and a call can’t be scheduled between them.

If you get rid of timezones they all say the same time, no? If you want to schedule a call you just say the time and save the timzone offset fiddling.

The real problem with time and date is that it has to fit social and natural systems as well as actual passage of time.

Can you give any more concrete examples? None come to mind beyond habit, which is not an immutable thing.

there must be a bit more to it than that. AIM, Skype, and several others were viable options with existing userbases.

Once upon a time in a messenger landscape far far away there lived a king called XMPP. It had a lot of powerful children, WhatsApp, Facebook Messenger, Google+, and even Skype amongst them. And they all worked together in a big federation towards the commonwealth of all, freely sharing their metadata. But then some of the children grew greedy, jealously guarding their own gardens behind higher and higher walls, breaking down the federation. And thus the era of the warring messengers began. But prophecy foretells of a prince to unite all the disparate standards in one big Matrix again, completing yet another revolution of the XKCD 972 wheel of time.

For real though it was phone numbers. WhatsApp always worked based off of phone numbers, which is an identity confirmation method that was immediately familiar to most people at the time, even more so than email.

Just highlighting the propaganda for those unfamiliar with it. Seemed à propos.

Agreed. And the (probably unintended) irony is that the Berlin Wall was ostensibly built in order to keep the capitalists out. Be careful what you wish for, especially when it's a wall. They work both ways.

Don't know about NY or multiple or if he even is a "real estate developer", but Jon Stewart made fun of a guy called Kevin O'Leary for saying so on CNN recently: https://youtu.be/EDMinX6t1Zk?t=577
