But why the changing of clock settings? Could have just shown up earlier to follow the sunrise?

Because numbers have meanings? So that 9-to-5 stays 9-to-5 the whole year round instead of 8-to-4, 7-to-3, 6-to-2?

If numbers had any meaning it would be even harder to justify a system where 1 hour after 2am is 2am

Is this based on the fact that the vast majority of people start work at arbitrary wall clock times, usually on the hour some time between 06:00 and 09:00, depending on profession? I'm all for keeping standard time just it makes slightly more sense for 12:00 to be the time when the Sun is highest in the sky, but surely any choice is completely arbitrary and the only thing that matters is the phase difference between…

You can't have 12:00 be the time when the sun is highest unless you're willing to shift to infinite time zones.

You can have it be closer to 12 than to 1 with only 24 timezones though.

It should be noted that the folks who study this: * https://en.wikipedia.org/wiki/Chronobiology Seem to have come to a consensus that if we're going to get rid of DST, then health-wise it is best to have Standard Time year-round: > As an international organization of scientists dedicated to studying circadian and other biological rhythms, the Society for Research on Biological Rhythms (SRBR) engaged experts in the fi…

Surely it depends on latitude and where you live in a timezone (as well as individual preferences). If Boston were to stay in Eastern time (and it probably would because New England switching to a different timezone than the rest of the east coast and an hour further from the west coast has its own problems), the elimination of DST would move sunrise back to about 4am in midsummer.

Longitude, but yes.

I think permanent DST makes more sense. The best hours of the day are in the evening. Folks are off from work, kids are home, the heat of the day is gone. It’s a great time to get out to a park or a stroll.

I too hate the idea of losing an hour off summer evenings. Of course, the rational solution is for society to adjust its schedule, but that will never happen.

Society constantly shifts the schedules, so the adaption would be done in a few years.

Social issues aside, the software perspective of keeping up with DST is very costly. Every time any government entity anywhere on Earth changes its mind about what zone they're in and when, the IANA needs to reissue the TZDB. Then every OS and platform vendor needs to patch up to a new TZDB. Just for laughs, Java seems to have its own TZDB so in general your OS and application layer might disagree about zones. This i…

Java also ships their own SSL trust store instead of using the system one. Why, just why?! Every system capable of running Java also has its own trust store...

You can't have 12:00 be the time when the sun is highest unless you're willing to shift to infinite time zones.

But you can set up timezones, so that the difference is minimal when rounded to full hours. The high point of the sun doesn't need to be precisely at 12:00, that would be silly, especially as the high point of the sun has a seasonal variation too. But we can keep the difference small.

The problem with the purely biological perspective is that it's too narrow. Psychology matters too. The benefit of an extra hour of light in summer evenings is measured in happiness . You can read a book in the park, play frisbee with friends, eat outdoors with family, with all the happiness that summer light produces. Nobody's measured it, but I have to believe that the increased happiness, reduced stress, and there…

I agree. And don't forget about an extra hour of light in the winter! It gets dark around 4:30pm in New York during standard time, it's depressing.

> I don’t know how someone ever could think this is a good idea Why is that? Whether or not it’s still a good idea, lots of people have thought so in the past. You don’t see the fact that governments have implemented it as evidence that there has been consensus and something legitimate there you might have missed? I honestly don’t care if daylight saving is abolished, but when I was younger, I used to think like you…

Majority of time that humanity existed that wasn't a problem. Maybe this was influenced by industrialisation and 9-5 culture. It would be great if we also left behind these rigid rules when people should work (certainly the new work from home adoption could help with that). I'd rather go to sleep earlier so that the 4am feels like 5am instead of force almost entire world to change their clocks.

> Maybe this was influenced by industrialisation and 9-5 culture.

Yeah, exactly right. Before industrialization, you’d simply wake up with the sun. If you ever go camping or on long outdoor trips, you might notice your schedule becomes suddenly much more aligned with sunrise. Mine does, anyway.

> I’d rather go to sleep earlier so that the 4am feels like 5am

That’s totally reasonable, but hard to achieve alone. We agree on the workday schedule norms together as a society. Flexibility would be nice, but much of industry depends on schedules and people physically working together, so they don’t (yet) have ways to relax the rigid schedules. Another thing to consider is the summer nighttime is less than 4 hours long (not counting any twilight at all). That means if you sleep 8 hours, you do have to choose which end to cut into.

This was already tried in the 70s and it sucked[1] so much so that we went back to the current method. It's strangely hard to find references though. [1] https://www.mercurynews.com/2016/10/30/the-year-daylight-sav...

This was different. They tried DST all year around. Russia also tried this in 2014 and also failed.

Assuming that people didn't like all year round DST, it's presumably because a lot of people actually like the shift depending upon where they live. DST year round means that where I live sunrise would be about 8am in midwinter. Meanwhile someone far west in a timezone is getting a relatively late dawn in the summer in spite of the fact there are lots of daylight hours.
