@Hypolite Petovan what would your alternative to timezones be that would not require sticking to a certain hour dictated by a specific jurisdiction and applying it worldwide though?

The current system is flexible enough to allow even increments of an hour difference (e.g. the time zone of Iran is UTC+3:30).

I kinda agree with the daylight savings time though. It's just a relic from a long-gone war.

@Cătă My alternative would be no timezone, and everybody uses UTC. What would change is business hours values. instead of opening between 7am and 9am worldwide, some would open at 07, some at 13, some at 22. And it wouldn't change anyone's habits. People would still keep trying to call others across the world on their downtime, jet lag would still be a thing since your body adapts to daylight, not time numbers.

What would change is that when you say a TV starts at 15, everybody would get it regardless of where they live. It could be early or late depending on people's local habits, but you wouldn't have to give 2 or three different time numbers depending on your target audience's timezones.

@Hypolite Petovan It would be weird to wake up at 22 to get to work and whatnot. Or to have the day end at noon or any time between morning and lunch. How could you call it a day this way? What about months or years? Would we still finish them in the middle of the day, or we would simply add a few extra hours to them? In the latter case, I don't see any difference to just take the UTC hour and add those hours to that instead.

What would change is that when you say a TV starts at 15, everybody would get it regardless of where they live.

That is a problem only for larger countries like the US, Russia, Canada and China. Many other countries in this world (including mine) only have a single timezone.

Imo I find it easier to manage my local time into daily chunks this way than to take UTC into account.

@Cătă It would be weird to wake up at 22 to get to work for about the same amount of time it takes to get used to daylight savings time change!

But you have a point about the day number change, it would be weird for it to change at any point that isn't during night, although night shift people already are used to it.

Imo I find it easier to manage my local time into daily chunks this way than to take UTC into account.

In that regard, if you just had UTC to take into account it would be the same for you after the initial getting used to it period.
