whenever clocks make things complicated, as they often do, someone inevitably declares: "we should just abolish timezones."
All right: poof. There is now exactly one standard time in use by everyone everywhere.
You try to arrange an online meeting and set it to be at 13:20. They write back: are you being serious? that's the middle of the night! Okay, so now you ask them what their usual business hours are, and work out where the overlap is.
It turns out this just keeps happening, so you need some sort of way to infer what someone's sunlight hours are without having to ask every person individually. It turns out you can calculate this pretty accurately from knowing their rough location, because the sun is pretty consistent like that. Hence, you can measure their offset from some arbitrary reference point and calculate their daylight hours, which you're probably going to want to represent in some sort of standard notation. It doesn't have to be precise to the second or anything, so you're probably gonna wanna break it down into zones of approximately the same sunlight hours...
You have become that which you swore to defeat.
