It was recommended multiple times in history, the problem is that it doesn't really solve any problems, just moves the problems elsewhere:

  • At some parts of the world "midnight" (the time when the day changes) will be during the "day". Would you like that you have to use a different calendar date at the morning and at the evening? It also makes much harder to check if something happened one or 2 days ago by simply checking the date, you would have to know the new UTC time as well
  • You still would have to know how far they are from you to set up an international call. Some people wake up at 2:00 UTC, some wake up at 16:00 UTC. So actually nothing solved, but you have to use different numbers instead of time zone names.
  • Time in China works like that, you can already see how it's going there. Full of China is one time zone, on its western border if you would cross to Afghanistan you would have to set your clock 4 and half hours backward. In Xinjiang solar noon is around 15:00 (3 pm). How people live like this? They simply use different timetables, 9-5 job is something like 11-7. So even it doesn't have a separate time zone people live like they would have a separate time zone.
  • Swatch Internet Time was a well known example of this in the late 90s, you can read the general problems with it on wiki

I'm in favor of global UTC, but the first argument is a really good one that I never saw before. You're leading me to reconsider.

Another potential solution to the mess of timezones does not work, shit.

Why is it a mess? I know from a programmer's point of view it is, I've seen the Tom Scott video a lot of times, but for average people it doesn't really matter.

Update to the video: they decided that they won't add a new leap second at least until 2035, and there are plans to switch to leap minutes instead, and sync to the astronomical clock once every century only.

Where it matters, e.g. international flight, they already use UTC for everything. How they solve this problem behind the scenes shouldn't affect the everyday lives of people. Computers use binary but we still use decimal system and noone want to change the numbering system. In a lot of places people use 12 hour clock in speech, but 24 hour in written form, and noone has problem with that. I don't understand why we should change it just because of the laziness of some programmers.

Plus you lose all of the cross-cultural understanding that's currently built into the time. The concept of what the number on the clock is and how that relates to the actual time of day has dozens if not hundreds of tiny bits of additional understanding baked into it depending on the situation.

In order to communicate these ideas, people would start referring to their local offset instead of the UTC and then we're just back at time zones again.
