I don't think global time would be a problem like many people suggest. If you're in US and talk to somebody in Australia, you will quickly develop an intuition that time @X is night (or whatever it happens to be) over there, just like our other intuitions about how many things (weather, season, how long are sunsets, etc.) are different in different places.

Timezones are failing at all of their jobs. Getting time to correspond to sun position? It can be 7pm here and 7pm there but here it will be fully dark and there it will be still mid-evening. Knowing working hours of shops and government? Everything is all over the place. Everything is fluid and changes with seasons.

Plus, there is this unfair specialness that some countries are at UTC and others have offsets. With global time, everybody gets @0, just for different places it will be at a different sun position. (As long as we find a political way to pick something neutral, instead of saying "that's when the sun is highest in London".)

Finally, we don't have per-latitude calendar and things are working fine for us. It's February here and February in Argentina, and yet life doesn't stop even though it corresponds to winter here but to summer there.

It's worth noting that technically London uses GMT for 5 months and BST for 7 months.

The GMT offset is zero, but it's important to note the difference especially when configuring servers to avoid nasty daylight savings surprises kicking in at at end of March.

There has been talk of moving to a +1 offset all year round for lighter evenings in winter, albeit at the cost of some very dark morning, but given we couldn't even manage Metrication without people still complaining 20 years later, I can't see it ever happening.

I think you mean complaining about metrication 50 years later :-)

The counterpoint is that without the metric system how could we make snarky comments on US-based woodworking videos?

Why not just offset the office and opening etc hours by +1?

[fragmede]

the obvious solution is to move it by .5 the whole year round.

Australian here!

I constantly forget which way the half hour difference is between Adelaide and Melbourne / Sydney!

Then I have regular contact with offices in London and LA. For some of the year it’s not too bad, and then our clocks switch the opposite way and it gets less convenient! Which way is which I can never remember.

Queensland doesn’t bother changing their clocks at all.

Writing software that deals with Timezones isn’t too bad these days, but supporting it is as it constantly confuses users I find!

You have some fun ones. On the other side of the spectrum is PRC, where at the same hour of day it can be complete darkness on one side and almost technically noon on the other. It's super arbitrary with little rhyme or reason.

I used to think this, but mirroring the sun position makes a lot of sense. If I wanted to meet w/ someone in Australia, I would still need to know extra information (what their equivalent 9-5 working hours are).

You would need to know that person's working hours, so I don't see how you are avoiding something.

Sure, if you talk to someone there for the first time, you would need to learn what time is generally day/night. However, you will know that 2-3 times in. Just like you would automatically know that now it's summer in Oz, or 3 hour short days near Arctic circle, if you talk to anyone from there even very occasionally.

Case in point, we have global calendar with no problems.
