All DST and time zones should be removed and we should only have one global time. People in different locations would just get up at different times on the clock. Communication about times would get so much easier, communication about schedules would get so much easier. "The same time every week" would have an actual meaning all year around regardless of any notions about getting up later relative to local sunrise in the darker time of the year.
This solves making the statement "let's meet at 5" be more clear globally, but doesn't solve the actual confusion. Person A getting up hours before normal, being in the middle of person B's day, and being when person C would go to bed still happens. All it does is destroy any frame of reference and make travel more difficult. You would still need a chart to know if any time was actually during waking or business hours at each location on earth.
It would reduce the problem to its essential complexity. Obviously if you coordinate with people from all over the world you need to check availability anyway, but at least that would be as easy as saying "Are you free at time x?" to everyone and not "Are you free at time x+offset that is different for every participant?"
Lots of people in your own time zone do not get up or sleep at the "standard times" for that time zone anyway. Time zones do not solve the issue you mention.
I have to look up the difference for every time zone not adjacent to my own now, I don't expect I'd remember France's preferred hours any more than I remember the time difference.
I agree that date formats other than ISO8601 ones are bad too but time zones, particularly combined with DST, wider time zones than standard and DST going the other way on the southern hemisphere are much, much more complicated than trying to figure out date formats.
Communication about times would get so much easier, communication about schedules would get so much easier.
Except that it wouldn't. It would make communication about time a culture sensitive topic. Sure, the exact time of day in relation to the position of the sun might get lost with our current system, but if someone tells you "I've slept til 12am" at least you know it was somewhat around noon. Under your new system you'd always have to consider where someone lives.
But in a way that's a good example for what I meant. You and me communicate time both in reference to the time of day, not a virtual time of the planet that means something else to everyone depending on location, and you easily could spot my mistake.
Is being able to communicate about stuff like that casually, where you do not mean a specific time anyway, really worth the giant pile of pain that time zones add to actual scheduling?
I mean what's more important to you, being able drop the info about time zones when scheduling international meetings, or preserving humanities ability to communicate time respectively to the actual time of day?
I've lived in three countries so far and never actually had trouble scheduling anything. The concept of time of day on the other hand is pretty prevalent in my daily life.
It is easy to remember, the am/pm system works the way that doesn't make sense (10am,11am,12pm...10pm,11pm,12am) unless you mentally substitute 0 for every 12.
The position of the sun is already not exact relative to the time. Check when the sun rises and sets for you. Very random times. The further away from the equator you are the fuckier they get.
I totally agree. It's not like the ~7-1700 time for my sunlight hours is super intuitive. If it was 23-11, I'd be fine after a few months, and a lot of problems would be solved.
Are you okay with being the one in perpetual darkness for all working and living hours while someone on the other side of the world gets to live "normally"?
You would just change the time you consider "working and living hours" based on when daylight is for you, e.g. if sunrise is at 1400 (instead of, say, 0700), your "day" would be from 1400 to 2300.
