Daylight Savings Time: Why is the US congress split on this matter

One thing to consider is that for all intents and purposes, US time zones are shifted 1/2 zone to the west. I’ve heard some proposals to split the difference and make the year standard time but make standard time +30 min which matches up with the current map pretty closely.

My apologies. I meant to say I was in same situation as @Procrustus. You lawyers on the pacific blend together. :blush:

Hah, I did wonder if you meant someone else.

Edited to add: DST is a highly controversial topic where I am, so I wondered if you knew this and had summoned me deliberately.

Under one specific definition of “noon” that is applicable to specific contexts. A more practical definition in our day-to-day lives is that noon is whenever our clocks say 12 p.m., and that is set by law, policy, and convention, not by the definition of geophysical noon.

OK, then why is it “most convenient and practical” to define Noon as 1pm? All time keeping has some amount of compromise to it, but moving to all-year DST is stupid and pointless. What possible advantage does it have over all-year ST?

Seriously … “unnatural.” This is a matter of natural law now?

Time keeping in our lives has always been a matter of practical policy decisions, and compromises, not appeals to natural law.

There are answers to that question right here in this thread, some of them by me, some of them by others. So Q.E.D. anything but stupid and pointless. Try an actual argument next.

Make an argument for switching noon from 12 p.m. to 1 p.m. and let it be evaluated as a policy matter then.

Yes, seriously.

Circadian rhythms are physical, mental, and behavioral changes that follow a 24-hour cycle. These natural processes respond primarily to light and dark and affect most living things, including animals, plants, and microbes.

The more we depart from solar time, and the more that time standards deviate from our natural biological cycles, the stranger and less healthy our lives become.

I think it’s naive to think it’s just a matter of politics. Screwing around with time standards that deviate significantly from solar time has reportedly had significant negative impacts in China.

I honestly don’t see any problem being “solved” by DST that wouldn’t be handled better by just re-scheduling activities that rely on sunlight. Changing the clocks to accommodate certain business and social activities seems needlessly paternal to me. If those activities need to start earlier or later, let them change their hours during those times of the year. And, forcing year-round DST doesn’t actually solve any problem that wouldn’t be better solved by making schools start at 8 as opposed to 9.

Right. So you don’t see how centrally changing a universal thing that is created by government policy in the first place might have practical benefits compared to… what …. Hoping that individual people and organizational entities will makes tens of millions of individual decisions to change them?

Paternalistic, eh? How much more paternalistic than having standard time at all? Why not let everyone make their own individual decisions regarding how to set their individual clocks? I’m sure Ayn Rand would approve.

I’m not going to get into this debate, DST is controversial where I’m from and I’ve heard it all before. It certainly brings out strong opinions. But I am going to say this, without being specfic -

It is right up there with the gun debate when it comes to bringing out really, really stupid arguments for positions for which reasonable arguments can be made.

So it’s moronic because the engineers at your company weren’t intelligent enough to program in a very obvious possibility?

Yup, my Wife and I too. It would be VERY strange to have it be light out when I get up.

Why not just split the difference. 1/2 hour, and leave it there?

I asked about this just last night, and the answer was that going permanently to Daylight Savings time was tried in the past, and it failed miserably. I was told that people didn’t like it. This was in a conversation, so there were no cites or evidence for this person’s claim at the time.

So, I looked it up myself and found this:

Why Permanent Daylight Savings Failed in the Seventies

Paywall. Can you summarize?

The basic information is available in the Wikipedia article: Daylight saving time in the United States - Wikipedia

What you’re describing as moronic is also called “moving” a blanket to cover something that isn’t currently covered.

Think of it this way, a man has a blanket that changes length throughout the year. When the blanket is short, he pulls it up to his chin, and leaves his feet uncovered. When the blanket is long, he pushes it down so that his feet are covered too. He has a definable preference for what gets covered first, and when the blanket grows short, he moves it to cover that area.

Rightly or wrongly, we have decided that we want a certain amount of light in the morning even if it means it gets dark early in the evening, but if it’s possible to have both light in the morning and in the evening, we shift the clocks to make both of them happen.

Thanks because you have to sign into the link I provided.

The thing about what they did in the 70’s was that the change to permanent DST was made in early January. Everyone had to push their clocks forward during the shortest daylight period of the year, when it would have the most negative impact on mornings. A better way would have been to simply not change the clocks in October, so people get to ease into the change rather than have it dumped on them at the worst possible time.
