Why don't we have one timezone covering the whole earth?

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.

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 poles

No! In summer time we'd be a whole hour out of our natural time! It would be too much to handle.

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.

In one of these stories you used Google and in the other you didn't. Both of these problems are solveable with Google

Just add 11 to utc.

No harder than having different times in different places.

You already have to Google for what time it is in another part of the world, and Google can also tell you when sunup, solar noon, sundown, and midnight are in Melbourne, so it sounds like you aren't any worse off without time zones.

If you actually want to know if the sun is up somewhere else, then you want a world clock. At a glance visibility on the current position of the sun for every location on the globe, no time zones necessary.

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.

Huh, you know what? I think you're right.

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.

Google tells me people are usually awake at 20:25 there.

Problem solved. This actually makes it problem simpler. With different time zones:

  1. Get local time.
  2. Convert to target time.
  3. Decide if your uncle is usually awake at the target time.

With one time zone:

  1. Get time.
  2. 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.
