> In Sweden, with DST, the sunrise is at 4am in summer and 8am in winter. In Sweden, in summer without DST, sunrise in Stockholm would happen ~2:30 AM. In the current system, with DST, sunrise happens around 3:30 AM, an improvement. In winter, if Sweden kept permanent DST (which is what many advocate for), sunrise in December would happen at around 9:45 AM. In the current system (shifting time back during winter), it…

Well, you certainly got a combative tone. I don't care if it's 8:45 or 9:45, it is what it is. You don't get more or fewer hours of sun, it's dark when you go to work, it's dark when you get home from work. With DST. Noon at noon is pretty much what the time zones are aiming for, yes.

> You don't get more or fewer hours of sun

Technically correct but false in practice. DST shifts sunlight hours to when people tend to be awake, giving the average person more hours of sun per day.

Sun received while asleep is not useful.

> Do the anti-DST people understand what they're advocating for? They do, which is why only 45 countries observe DST. 25 observe it partially. And the rest, roughly ~125 countries do not. Historically, ~140 countries did. To put this into perspective, only about 1.2B people out of 8.3B observe it today. Which puts you into a very small <15% minority.

Appealing to population is a stupid argument. DST as a policy is designed for places at higher latitudes, and the the majority of the planet do not live at higher latitudes. DST exists to maintain a more consistent time of sunrise across seasons. DST is moronic in any part of the world close to the equator. There is not enough seasonal adjustment in the time of sunrise to justify adjusting the clocks. And in places o…

Queensland may be, but Brisbane is not relatively close to the equator. Its 27 degrees. Tip of cape york is 10 degrees, thats a pretty big difference. It can be dark in Brisbane and still light at my parents house near cape york.

Cape York is also 10 degrees west of Brisbane. That alone gets sunset 40 minutes later even if you stay at the same latitude.

I feel like its.. much longer than 40 minutes.

Oh my God, just move it by half an hour permanently!

That doesn't fix anything, the reason DST exists is because at higher latitudes, the sun rises too early in the summer, and too late in the winter. DST exists to make the time of sunrise more consistent across seasons. DST only functions if hours are shifted seasonally, once for summer, and again for winter. Have a look at a sun graph to understand why https://www.timeanddate.com/sun/usa/seattle

What? It fixes everything! It means you never have to change times again. That singular benefit overrides anything else. what's wrong for summer is right for winter, and vice versa, but if it's equally bad it's also equally good.

The jobs need to run at midnight, local time. Which shifts from UTC. How to handle?

Why does it need to run at that time? * If it's being run to scrap data from a source that's available at some time, adjust the job if the source changes its time. * If it's being run "when its dark and no one is around" then it'll run at some part of the dark bit regardless of DST changes.

Billing and regulatory compliance

In that specific case, handle the job time by making it compliant.

The reason I posed a leading rhetorical question was that not all cron jobs are equal and how each is handled depends on the nature of each.

I live in a hot desert climate where most of the daytime during summer is inhospitable to human activities. We also do not observe DST at all, and that makes us a red-headed stepchild in America. I have longed for a system here where summertime means a 12-hour DST: everyone sleeps all day and then goes to work/school in the coolness and darkness of nighttime. I absolutely love chilling outside in the dark when the lo…

I don't understand how Arizona lives during the day for like 5 months. It's too darn hot there, and because it's dry, nighttime is way cooler.

It is instructive to learn that the colonization of the Phoenix area and other desert urban centers coincided with the establishment of railroads, the shipments of ice and chilled products on those railroads, and of course huge waves came with the popularity of the chiller and air conditioning systems.

Of course, the indigeneous tribes and early explorers/homesteaders made a living here without those machines. I've heard tell of various methods for coping with the blistering heat, and if my A/C ever breaks in here, may try 'em out, but that's "surviving" rather than living, IMHO.

DST is bad because it changes the clocks in huge jumps. Very poor for people's health. Noticeably increases excess deaths.

Fixed clocks are bad because they don't track the sunlight.

We should change the clocks by 10 minutes, every month. Keep dawn at roughly the same time every day, say 06:30. Add enough time zones so that dawn will always be within 10 minutes of 06:30 at the equator for a given longitude.
