In the name of logic it seems to me that a worldwide paradigm shift away from human-(un)friendly time zones to UTC with 24 hour clocks would do wonders. We're stuck with our present system, and instransigence means we probably always will be.
Sure there are other ways we could communicate offsets, days, whatever, but having everyone on the same daily schedule and just adjusting the schedule itself keeps it simple for most of the population.
Yes, there are a lot of weird often politically-motivated time zones out there but for the most part it works
