xkcd #3272: Time Change

Title text:

All discussions of daylight saving time policy are doomed by a mix of contradictory, inconsistent, and impossible preferences, which is why I think the only thing we can really hope to do is to make it worse.

maybe we could restructure our society so everyone gets enough sleep according to their own circadian rhythm. that would be cool.

[-] sundray@lemmus.org 54 points 2 days ago

I don't know... that sort of thing might not make billionaires even wealthier.

[-] applebusch@lemmy.blahaj.zone 26 points 2 days ago

crazy fact, well rested people are more productive than tired people, and more productive people make more money. but we all know it isnt really about the money for them dont we?

[-] sundray@lemmus.org 15 points 2 days ago

Honestly, the wealthy just want us to be miserable.

[-] Axolotl_cpp@feddit.it 1 points 1 day ago

Do you think they are so smart?

[-] dumples@piefed.social 7 points 2 days ago

Dumb. Much better idea is to split the daylight into 12 equal chunks and the night into 12 equal chunks so we have 24 hours a day 12 of which are light and 12 of which are dark.

It's so simple. We just got to change the definition of an hour everyday.

[-] drosophila@lemmy.blahaj.zone 3 points 1 day ago

They used to do this. Hours were divisions of the day, like slices of a pie, rather than a specific length of time.

Using equal hours, and dividing them into minutes, was something only astronomers did to help with their calculations.

[-] dumples@piefed.social 1 points 1 day ago

It kind of makes sense in a way. It feels more natural

[-] Hamartiogonic@sopuli.xyz 13 points 2 days ago* (last edited 2 days ago)

An 8 h work day during the winter flies by, but the lunch hour is only long enough for one bite sandwich. On the other hand, 12 h of night is plenty enough for all my hobbies.

In the summer, work devours your entire life and there’s hardly any time to sleep.

[-] grranibal@lemmy.zip 6 points 2 days ago

Just normalize 4h work days :D

[-] Hamartiogonic@sopuli.xyz 3 points 2 days ago

Sounds good to me. In this case, 4 flexible hours of work in the summer means about 6 fixed length hours. In the winter those 4 flexible hours translate to about 2 fixed length hours, so I think I'll have plenty of time for my hobbies.

[-] grranibal@lemmy.zip 2 points 1 day ago

One can dream of such a beautiful future

[-] dumples@piefed.social 2 points 2 days ago

This is exactly what I was thinking. Smaller working hours. Or at least smaller around the peak of summer and winter.

[-] dumples@piefed.social 1 points 1 day ago

Twice a day or once a day for the day hours length vs night length hours. Also for every latitude as well. What a simple system

That can be read both as intended, and as if congress has the debate every spring and fall. Both of which are true.

[-] ClownStatue@piefed.social 16 points 2 days ago

I love it when the occasional person comes through arguing that we should just get rid of time zones so it’s the same time everywhere. Always a fun discussion.

[-] TwentySeven@lemmy.world 7 points 1 day ago

What about splitting each time zone into 60 parts, so they are in increments on 1 minute instead of one hour?

[-] ClownStatue@piefed.social 2 points 1 day ago

Fantastic idea!

[-] BlackLaZoR@lemmy.world 1 points 1 day ago

Half of that looks like an American defending imperial measurement system.

[-] WraithGear@lemmy.world 6 points 2 days ago

it exists already. but besides that. what numbers are assigned to what sun location is completely arbitrary and a man made convention.

if my 7:00 turns into 14:00 my job will expect me at the new 14:00

[-] ThatGuy46475@lemmy.world 24 points 2 days ago

We can make up for it by skipping a leap year every 24 years

[-] atomicbocks@sh.itjust.works 8 points 2 days ago

I hate to complicate things but we already skip leap years…

The Gregorian calendar, the world's most widely used civil calendar, makes a further adjustment for the small error in the Julian algorithm; this extra leap day occurs in each year that is a multiple of 4, except for years evenly divisible by 100 but not by 400. Thus 1600, 2000 and 2400 are leap years, but 1700, 1800, 1900, 2100, 2200, and 2300 are not.

[-] JcbAzPx@lemmy.world 1 points 1 day ago

That's leap days. We also skip leap minutes occasionally. I think we've only removed whole years in retrospect.

[-] Armok_the_bunny@lemmy.world 1 points 1 day ago

Leap year is the term for the year a leap day occurs in. I also don't believe there have ever been full leap minutes, just leap seconds.

[-] BlackLaZoR@lemmy.world 5 points 1 day ago

How about using same time for entire globe?

[-] Yeller_king@reddthat.com 6 points 1 day ago

Sure as long as the globe adopts the one I live in.

[-] OhStopYellingAtMe@lemmy.world 6 points 2 days ago

Better idea: hack the Earth’s code and do away with this annoying axial tilt thing. It’s super inconvenient.

If you modify the hypnogogic prompt you might get away with it..... Or enable a nuclear war.

[-] Floodedwomb@lemmy.world 4 points 2 days ago

I just want the sun to go down by 7 every day

[-] Hueristic_Autistic@lemmy.world 2 points 2 days ago* (last edited 2 days ago)

You do realize changing the idea of changing the clocks to be either one hour forward or one hour backwards doesn't change the fact that the sun changes position throughout the year.

The summer will feel long and the winter will feel short no matter what. At least in the US.

You can hate it all you want but it's to account for the fact the days do actually get shorter and longer.

[-] JcbAzPx@lemmy.world 7 points 1 day ago

Take it from someone who doesn't have to change their clocks, it's way easier to deal with that way. The whole process is so gradual you barely even notice it.

[-] Hueristic_Autistic@lemmy.world 2 points 1 day ago

Well I guess in New England it works out better cause it does get dark out earlier in the winter. It's like some Baltic regions being am/pm vs 24hr.
