But in order to see if 1600 universal time is a good time for everyone involved you'd need a system of charts telling everyone what time of day each time represents at different points across the world, and just like that you've reinvented time zones.
You really don't lol. Again, you're overthinking it. Everyone has to do that already. I say can we meet at 18:00? No, how about 19:00? Yeah that's late for me but sure we can make it work.
That's it. That's already how it goes lol.
The change isn't really meant for those parts anyway. It's for the people who actually keep the world running logistically lol. That's just the easiest to imagine for most.
Yes that do be how lots of people talk online when you can't verbalize inflection through text lol.
UTC is essentially what a solar standard time is advocating for. It's just enshrining it as the defacto time, because it's superior in every way from local. It's going to be adopted regardless of what people want in the future.
Reading through the thread with other replies gives numerous examples of how poorly implemented local times absolutely screws over stuff like computer programming requirements. Let alone the fact that we've already standardized every other useful measurement in the world through metric in non-imperial countries yet somehow, time shouldn't be! It's such a silly anachronistic viewpoint made only difficult by people fearing even the slightest bit of change despite the usefulness for countless others you'll never meet.
