Yes. But, that’s also only 4 time zones squashed into one, with vast majority of the population living in 2. EU could remove time zones, US too, but worldwide it would be quite unpleasant to completely lose the notion of when a « morning » is.

Also not to forget that currently midnight and the associated change of the calendar date happen at a time when most people are either asleep or otherwise don't really care about that fact.

Not having time zones means that everybody except the privileged minority living near wherever the new meridian ends up will have the calendar date change during their waking hours, which will be rather confusing.

Plus how are things that are currently specified at the granularity of calendar dates supposed to work? Do public holidays and suchlike suddenly start and end at something like for example 3 o'clock (solar time) in the afternoon, because that's when the new midnight (global time) happens at your location? Or does everything now need to specify starting and ending hours, too? Or do you decouple the change of calendar date from midnight (global time), which basically means reintroducing time zones through the back door…

My 5 cents from the antipodes (NZ, so it really should be 10 cents): yes.

For so much of what we do, we have to do it on Europe and North America’s time. Being able to say “if we want to join that 9am conference call in New York, we have to be up at 1am”.

Taking out time zones and saying “oh good, the meeting is at 9am” doesn’t help me to know what time in the middle of the night I have to be up — other than that it’s 9am, which isn’t helpful.

The whole am/pm thing would also probably need to be ditched for military time. (Now that is a thing I would agree on doing anyways)

That’s just a different way to format the same thing. It doesn’t stop the sun being up in one place and down in another.
