Ask Lemmy

Long discussion here. I feel I'd like to add two things. First: we already do. If you coordinate international video calls or conference live streams, you'll say it starts 14:00 UTC. That is something we can do and regularly do. Some companies will use the timezone of their headquarters, though.

Furthermore: Once you're already in the process of changing how time works, don't do a half-assed job. Go all the way and make it metric. Do away with all the 12/24 and 60s. And make things divisible by 1000.

Swatch Internet Time tried doing something like that

Because timezones were a result of town specific clocks, which were a result of people liking certain hours happening generally in line with where the sun is, like "noon" which still technically refers to when the sun is at its highest point.

Almost a century ago, the fascist dictator of Spain wanted to appease Hitler and decided to move the timezone from the UK one to the German one. With daylight savings the situation in summer was a bit ridiculous: dark until 9 am and sun until 10 pm, it was very confusing as a tourist to have all the stores to open so late in morning and go out to eat dinner so late

I can't imagine what kind of mess would be going to Japan as a tourist on UTC+0

Because who the hell wants to say it's 11 in the morning while it's dark out?

I'm now imagining that playing out.

"France, we're thinking about adopting British time as the global standard. Do you have any thoughts or input on the matter?"

because despite all the technological advancement, we still live enclosed in these self-ambulatory lumps of flesh that crave the sun.

TL:DR -> https://thelemmy.club/comment/19143233

Examples:

• The year doesn't start at the shortest day (Persian calendar is better in that regard).

• month length is not evenly distributed. Why is February shorter?

• time is almost never power of 10: there is 12, 60, 24

• time zones are used to follow alliances: see al the nations that went to CET after fall of URSS

• you can easily estimate your local time by looking at the sun

• Holidays tend to happen on the same approximate dates even when major cultural changes happen. See how Christianity took over a lot of things from Romans.

Why should the UK get to be the only place with an accurate local time? I don't want to live on UK time.

because we sleep at night and are active during the day, and so we need to track that in a way that is universal. if i mention 12:00, people understand that it is noon where i am, and if i mention 22:00, they know it's bedtime.

the whole point of time zones is to have time cohesion in a wider region within margin of error, so people on the far east and far west of a time zone still see the sun at roughly its highest point in the sky at 12:00. you can take a train to a neighbouring city without having to worry about needing to adjust your timekeeping devices by a few minutes.

to put your scenario into perspective, china has already done what you suggested on a smaller scale: the entire country is on UTC+8. this is great for cities like beijing and hong kong
