please don't ditch timezones.

The thing I don't like with these kinds of articles is rather than list potential pros/cons they make a wholly one sided story everyone is supposed to agree with the whole way and say "oh wow, yeah" at the end. Reality is it breaks right at the start - you don't really know when a good time to call someone is by the sun. You know because of when they wake up, when they go to bed, what hours they work, what you're calling them about, when they like to eat meals, etc. All of that varies by many hours within a timezone based on culture or individual, so it derails that build up pitch. It's a given the author isn't particularly swayed by that, but that they don't even talk about the detail and just move on spoils the rest of the (well put together) list IMO.

One way or the other I don't think we'll make a big shift in timekeeping until/if we ever have a sizable population off Earth. Of course, that introduces its own time problems we don't have to deal with as much all being so close together :).

I don’t personally see a lot of difference in consulting a chart of “what time is it in x country” vs a chart of say “the time business starts in country x”.

They’d be the same exact list. “offset +9 hours”- the only semantic difference would be that clocks don’t change.

I should mention that I spent a little bit of time in Saudi Arabia and expecting them to be out and about at 7pm like in Western Europe and the USA is crazy, they seem to get up later and keep going until 3am. I’ve never seen rush hour at 3am until I spent time in Riyadh. It’s a false construct we’ve decided on: that everyone follows the same time pattern anyway.

Why do we believe the world needs to wake up at 7am? If nothing else its so incredibly arbitrary to begin with.

I never found those arguments for keeping time zones particularly compelling. Everyone has their own schedule, trying to standardise time to sync people up is silly, you sync by talking to them and asking them what times they are available. The number on the clock doesn’t actually matter.

But DST affects us exactly because people tried to standardise on time AND then shift that meaning twice a year. If we ditched timezones, then businesses could say ok we will work from 1700 until until 0100 or whatever, based on time relative to sunrise, it it would be consistent all year round.

The thing is, regardless of timezones, you have to ask people what times they work or are available or whatever. Also consider that timezones are arbitrary and made up anyway: china physically spans the space of 3 timezones yet the entire country uses one timezone.
