You realize that the amount of daylight does not change, right? The important thing to me is that noon should be as close to midday as possible.

Because that’s the definition of noon…

[-] dubyakay@lemmy.ca 6 points 8 months ago

That's very arbitrary.

The sun is at the highest when the sun is at the highest. It's called the solar noon. If you are in Thunder Bay, it happens arouns 1PM EST/2PM EDT. If you are in Gaspé, it happens around 11:20 EST/12:20 EDT.

See how much binding the timezone to a specific shift doesn't make sense based on your arbitrary metric?

[-] Hawke@lemmy.world -1 points 8 months ago

All that means is that the layout of the time zones is stupid. Noon is noon, and my opinion is that clock noon should be as close to solar noon as possible.

or we should eliminate time zones entirely and use a single clock time worldwide.

Eliminating time zones would be pretty amazing.

If we eliminated DST for the summer, or would not have permanent DST, we'd need to change culture to not have 9-5 banking/office work days but rather 8-4, 7-3 or 6-2, similar to how the trades already work.

Realistically we already do. There’s enough variation in start times… yeah 9-5 is traditional but plenty of places have slightly different times

There are actual health recommendations based on solar time. For example, we are cautioned to be especially careful of summer sun exposure between 10 am and 2 pm. As far as I know, that makes sense only in the context of solar time: the 2 hours on either side of when the sun is at it highest (solar noon.)

Unless there is something about the actual timing of the risk I don't understand, under DST the recommendation should be "between 11:00 am and 3:00 pm."

Where I am, in Saskatchewan, my local time is about 1.5 hours distant from solar time. Thus, that recommendation should be "between 11:30 am and 3:30 pm," although I suspect 11-3 is close enough.

That would require a lot more timezones. Solar noon fluctuates by an hour depending on which side of the same time zone you're in, and that's not even considering all the timezones that are offset for geographical convenience.

[-] jadero@lemmy.ca 1 points 8 months ago

I obviously didn't write clearly. I'm not objecting to DST or timezones as they exist. I'm was trying to point out that there are unresolved disconnections between solar time and the ways we want to set our clocks.
