My dream world would have 86400 time zones, one per arc-second of the globe, so we can all sync our clocks at high noon.

My favorite depiction of your dream world: https://qntm.org/abolish

My dream world is we apply time zone logic to every other unit of measurement.

1 metre can be 100cm or 200cm depending on the season and your location

And then it's going to be so fun guessing at which time each country in the world starts working

Time zones are a pain, but it might be too much to fix.

Now, 13 month calendar with each month 4 weeks, on the other hand..

But if we abolish time zones how will we keep trains from hitting each other on the tracks?

Sounds good on paper, terrible idea in practice.
