US Senate votes unanimously to make daylight savings time permanent

@elmerfud 3 months

Replying to @enraged_camel 🎙

The hooray the Senate is saving our daylight I'm glad somebody is. Take care so much what would we ever do if they didn't save this daylight for us. Maybe they can take some and put it in a lock box for when we need it most.

Where's my screwdriver... I have to remove some DST toggles.


@ilovesunlight 3 months

The sun sets about 2 hours later during the summer than the winter (depending on lattitude). DST adds an extra hour. In other words, 2/3rds of the "longer day" effect is from earth's tilt, and only 1/3rd is from DST. Seems like some people misunderstand this.

As long as they eliminate the constant inane switching back and forth. Sleep disruption is harmful in many ways and all this practice seems to actually do, old wives' tales about farmers and circumstantial localized benefits aside, is induce it. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5449130/

Thank god. Every change causes hundreds of millions if not billions of dollars in damages.

Case in point-- my pool cleaning pump that was supposed to run for <1 hour managed to stay running all night long because its shutoff time was during the missing hour. Fortunately, I was aware of the potential issue and checked it and stopped it before there was any damage.

This is in spite of prior years effort to fix this specific issue.

This same kind of dysfunction is repeated all across the country from homes to industry. Thousands of tiny cuts, significant increases in automotive accidents, and a measurable increase in all-cause mortality even excluding the auto accidents.

After this is activated the next damage producing time meddling to fix is leap seconds: Without leapseconds it'll take 4000 years for solar time to drift an hour -- and if people still exist care about solar time agreement with some arbitrary clock numbers at that point they can simply adjust all the timezone definitions by an hour at that point and be good again for thousands of additional years.

Like the DST changes leapseconds cause an enormous amount of disruption and failure and as more of our electronic systems depend on precise synchronization the amount of disruption is only increasing.

While the displacement of leapseconds is shorter, they are more rare than DST changes so systems are less likely to be tested against against them. In particular, we haven't had a negative leapsecond before but they're possible and one will almost certainly happen in the not-distant future if we continue to apply them.

Unlike DST whos times are perfectly predictable except for politics, leapseconds also have to be signaled shortly before they apply. This creates a massive amount of additional complexity and avenues for error and security vulnerabilities. With the development of solid state atomic clocks we could reasonably expect to see affordable timing devices that never need to be set in our lifetimes, -- but they couldn't keep accurate time in a world that used leapseconds.

Me work with a US-based boss so he changes our call one-hour earlier when it comes. Kinda confusing to me when it comes to the switching happens. Everytime.

We didn't even observe it here in Indiana until something like 16 years ago and it is the dumbest thing that I've ever been a part of.

As an avid astronomer and someone diagnosed with SAD, this hurts double. This is going to kill me in the winter.


@mobilene 3 months

I live in Indiana, where we didn't change time at all until ...was it about 10 years ago? I forget. We were EST year round It was wonderful not to have to deal with DST.

But then we started observing DST and ...glory be, we had sunlight in summer until after 9 pm! That was quite a revelation, and very welcome.

So I'm all for permanent DST. Or putting Indiana in the Central time zone and observing permanent Standard Time.

But that ignores the people on the other side of the Eastern time zone who have a very different experience with when the sun is out.


@sylware 3 months

I guess this is removed useless complexity.

EU should follow soon hopefully.


@mazlix 3 months

I guess I'll be "that guy" and say even though it's a disruption I feel a bit sad for the loss of the switch between standard and daylight time.

Yeah it's annoying, but I never found it devastatingly so and it's almost like an extra 2 holidays, I would occasionally get an extra hour once a year (and also lose an hour). I feel a bit sad knowing my child won't get that feeling of dread having to go to school one hour earlier and that boost of going to school one hour later. It feels like the world is become more practical in so many ways, but with it we lose some flavor.

I also love seasons and dislike places that are the climate year round for the same reason - it's a little extra something that breaks up the monotony. At least every time-shift you know that half a year has passed. I really imagine a lot of people will become very nostalgic to having to change clocks throughout the house and then eventually it'll die off and become a completely forgotten relic of the past.

I will love it when my sleep schedule isn't disrupted twice a year for no good reason. I can stand waking up in the dark or getting off work in the dark. I just hate having to adjust my circadian in order to reduce candle usage...


@AngryData 3 months

How about we just abolish the whole debate by moving the clocks 6 hours and making it permanent. Then nobody can complaint about sunrise versus sunset times because they will have to choose new hours to start and close at anyways and they can make it whatever they want. It shouldn't be necessary, but I find this entire debate ridiculous to the extreme. The clocks don't determine your hours of activity and sleep, you and your business does and they can be changed at any time for any or no reason at all.


@_Nat_ 3 months

Glad that they're trying to simplify it, though it'ld seem obnoxious to maintain a 1-hour addition to the discrepancy between solar-time and clock-time.

It'ld seem far more sensible to have a system that tries to align clock-noon with solar-noon (this is, noon on a [sun-dial](https://en.wikipedia.org/wiki/Sundial )). After that, if folks want to change whatever times work/school/etc. are at, awesome, folks can change such times -- as a matter of scheduling, without obfuscating clock-times.

I guess it doesn't matter too much. Computers should be able to re-interpret times, such that different folks in the same community could use different time-systems, while computers would automatically interpret between them for users' convenience. Then, folks could pick the time-system of their choice without regard for what their peers use -- much like no-one cares what font-size others use -- rendering the exact choice of standard a relatively low-level primitive-formatting-detail.

I am an idiot. Would this mean that the time stays as it is right now (after the change from this past weekend)? Because I would love that so much.


@kalium-xyz 3 months

Man I wish we could get rid of timezones. I know its psychologically impossible for humans to adapt to it but timezones really haven't made sense since clocks became a thing.


@mdavis6890 3 months

Bad idea.

TimeZones and DST are for humans and physical realities, such as the tilt of the earth and circadian rhythms. And they serve to address these things in a universal, coordinated way rather than asking each of us to change our schedules individually.

During DST, we all agree to start our days, open our business, and adjust our schedules one hour earlier, but without changing our individual clock times.

With DST all year long, can we choose to send our children to school at 9:30 instead of 8:30 during the winter? Should the school have a different winter schedule than a summer one? Or should we just wake up our young children well before dawn and drag them off?


@ithkuil 3 months

For me the main madness was not DST but the fact that countries (in particular US and EU) start and end DST at different dates.

Honestly, I don't get the complaint about one hour change two Sundays a year.

But the several weeks a year of conflicting meeting bookings in companies that cross the pond is much more infuriating.


@standardUser 3 months

I love this. I'd even go as far as to support permanent double daylight saving time. Let's get those daylight hours in the evening where they can do some good!

@dav_Oz 3 months

For anyone wondering how our bodies synchronize to a 24-hour-cycle of the earth, it is primarily through light detected by our eyes. (A great resource for in depth: Professor of Neurobiology and Ophthalmology Andrew Huberman [0])

Apart from cone (RGB) and rod cells (brightness) which are responsible for vision in general (through the "-opsin" proteins: photopsin and rhodopsin, respectively) we also have a more ancient distinctive third class (subconsciously: not taking part in any vision at all) which was first discovered in the light-sensitive skin cells of the African clawed frog in 1998: intrinsically photosensitive retinal ganglion cells (ipRGCs), which express their own distinct opsin—melanopsin. Melanopsin cells in mammals are specialized for measuring ambient illumination, contributing to visual discrimination, and driving a wide variety of physiological responses including, but not restricted to: synchronization of circadian clocks to light : dark cycles, regulation of pupil size, modulation of sleep and suppression of pineal melatonin production.[1]

So, even if you are blind those important signalling cells could be still intact. That's why one does not remove the eyes for 'cosmetic' reasons, anymore. This circadian feedback system functions ideally when all three parts of our photoreceptors are working in unison but can still function - albeit to a limited extent - if just one part is available.

To not confuse "noons" we can categorize those in three ways:

(i) solar noon: the time when the sun is at the highest point, at a specific day, at that exact location on earth

(ii) local noon: static time-zones i.e. conventionally set. Normally within +/-2 hours of the solar noon.

(iii) biological noon: adjustable through the light from outside but without any light input it varies from person to person (a "night-day"-cycle could be anywhere from 23.5h - 24.5h long).

There are roughly three time windows in which the photoreceptors of the eyes synchronize our bodies to the outside world, the first and last being the most important ones:

(1) After our physiological temperature minimum, normally about 2 hours before we wake up, naturally. Here the "biological noon" gets set, initially. The window closes some time about that point (I couldn't find a reliable number, anywhere, my guess is about 2 hours in, so about 4 hours after the "temperature minimum" the window closes and one is locked in the "dead" zone, for now).

(2) When the sun sets down. Experiencing the change and reduction in light helps the body to anticipate and prepare for the last window.

(3) In the last phase everything gets reversed, in order to not disrupt melatonin production ("hormone of darkness and sleep initiation") it is vital to not emulate the sun (bright, overhead). The best sources of light are low-hanging warm lights and just enough brightness to feel comfortable. Here, you have to take into account the adjustment period for your eyes. Unfortunately most people aren't used to see adequately and orient themselves in low brightness settings (peripheral vision). Star-gazing could serve as a starting point for some sensibilization.

Those biological insights can be used to balance and fine-tune one's circadian rhythm.

But the most reliable and effective way in getting the system into full gear, is how this elaborate system evolved in the first place: outdoors. Living outside for a couple of days, on some weekends of the months for example, to "reset" can work wonders: a substantial set of people who think of themselves being night owls are actually fooled into it by artificial lights ;) [2]





@basisword 3 months

Can someone explain why they actually care about this? I always see such strong opinions on it but really, why does it matter to you? Most clocks are digital and change automatically these days and otherwise changing your clocks twice a year is such a minor inconvenience. And whether or not the light should be preferred in the morning or vending is probably a pretty even split. Maybe it’s better to get rid of it (I don’t know) but to care about it strongly seems odd. What am I missing?


@paxys 3 months

Priority 1a – Daylight saving all year.

Priority 1b – Standard time all year.

.... bottomless pit ...

Last possible priority – Switch clocks back and forth twice a year.

It would suck so bad if because of the fighting between the two preferable options we are stuck with the worst one.

It always bothers me that the Congress.gov bill tracker seems to never be up to date. How hard can it be?



@kseistrup 3 months

In Denmark (EU) we are currently switching timezones twice a years, which is a huge PITA for people like me with a sensitive circadian cycle.

The EU has opened for the individual countries in the EU to settle on permanent DST or permanent normal time.

In order of preference I choose:

1. permanent normal time

2. permanent summer time

3. switching between normal time and summer time twice a year

Not to be confused with "sunshine laws", and using that word for an unrelated legal measure could, uh, cloud things.



@alerighi 3 months

I will never understand why we change the clock instead of changing our habits. Well, maybe in a time when we didn't have computers it was simpler to just put the clock ahead or behind an hour, but nowadays it creates a ton of complexity for nothing. Isn't it simpler to just shift our times, for example in the summer start to work at 9:00 and in the winter at 8:00?

Beside, if we have to choose a time, why not choose the solar time and shift all our times one hours, at least the sundial are right...


@robbrown451 3 months

While we're at it, can we please get rid of leap seconds? (which we don't know are going to happen until ~six months beforehand?) Just wait until we are off by a full minute, and then we'd know at least a full decade ahead of time when the next leap minute will happen.

I don't understand the need to have it so precisely align with astronomical measurements (to the nearest 0.9 seconds) when we already do so much roundoff due to time zones, daylight time, etc.

I love the title of the bill: "Sunshine Protection Act". This is great news. I am in Australia, and if this becomes law in the States it is more likely to be seriously considered here. We have a situation with half the country on DST and the other half on standard time. It hits a lot of us very hard at the end of April when DST ends.

Obligatory link to previous attempt (1973) to make DST permanent:


TLDR: schools asked to reinstate DST because more school children were killed in accidents walking to school in the dark that year.

@globular-toast 3 months

I'm completely in favour of not regularly shifting the clock backwards and forwards, but making daylight savings time permanent instead of standard time is so dumb. I guarantee this is because people think they will "get more daylight" or something stupid like that. I guess this is the pragmatic solution to getting people to agree to stop the shifting but damn, we are so far from Star Trek right now.


@razzimatazz 3 months

I like that this is such a wholesome topic we can safely debate on the internet. There are clearly good arguments for and against the change to permanent DST, so I will safely ignore anyone presenting statements of the "You must be an idiot if you think..." form.

There's no disinformation campaigns to worry about, nobody getting 'cancelled' for their poor arguments on the topic, no fraudulent studies being passed around. At least, for the time being...

I am extremely surprised at all the people who are against this, saying that "Making DST permanent forces people to wake up earlier." I am not sure I know a single person whose morning wake-up time is dictated by the rise of the sun. Everyone I know wakes up whatever time that their work tells them to.

I am happy to have more sun after I get out of work. It was a breath of fresh air this week getting out of work and seeing daylight.

@seangrogg 3 months

I'm all for either implementation of this (standard or savings); I have no particular skin in the game when it comes down to where daylight hours are positioned. Having lived about a decade in Arizona it literally never negatively impacted my life once.

Since moving I've come to participate in what seems to be the standard dread of moving hours back and forth. I either lose sleep and need to adjust my Circadian rhythm or I gain a one-off hour to... I dunno, lay in bed longer because I've already gotten my sleep?

The worst is being a gaming raid leader (and I'd imagine anyone dealing with globalized scheduling), though, because every time we do this I have to reach out to my gamers in other states/countries who don't play collective clock madness and ask them to adjust to those of us that still do for what appear to be largely outmoded "reasons".

All I can say is that it must take alot of confidence, for lack of a better term, to look at what time the sun goes down and to decide that you are going to change that.


@chrysoprace 3 months

Speaking as a non-US person, I think this is great so long as it's across every state (can't tell from the Tweet). Here in Aus, whether to have daylight savings is determined by state/territory, which means that for half the year the entire East Coast (except for the biggest state by land area) is an hour ahead.

Barro is very fond of pointing out that we tried this once in the 1970s and almost immediately rolled it back. Permanent DST means that it's dark between 8-9AM in large swathes of the US. Among other problems, having kids go to school in the dark or twilight hours is unsafe, so schools responded by adjusting their schedules, which is an even bigger problem than DST, because the rest of the economy has a de facto requirement to coordinate with school schedules.

I'm surprised at how positive the response to this has been.

Whenever I've tried to reason through why we change our clocks twice a year I've found that it makes sense to do so (at least in my case).

Also, I've quite enjoyed experiencing the switches throughout my life. They've provided for a mildly entertaining small talk topic, an opportunity to fix my circadian cycles and some measure of excitement when getting to sleep for an extra hour.

That said, I recognize (now that I've seen this HN thread) that a LOT of people disliked the status quo of having to switch.

I just hope that my country won't follow the US in this, but I'm afraid we will.

@aj7 3 months

Now we get to remember the why of Daylight Saving Time.


@zentiggr 3 months

Let's end the debate, assuage the farmers who opposed time changes from the beginning, and honor every other timekeeping system in our earlier history:

From now on, sunrise is 0700. The clock runs from 0700 sunrise to whatever time necessary overnight to arrive at sunrise again, at which point the time becomes 0700. For the part of the year where that duration is greater than 24 hours, the time past 06:59 simply counts up extra seconds until reset.

Now we can have computers and every other carefully regulated timekeeping system on milliseconds since an epoch timestamp, and regular old clock time fits everyone's schedules regardless of time of year, and never needs 'adjusting' again, since its sun-synchronized.

And people said Y2K and the Year 2038 issues were hard...


@slavik81 3 months

This is nice to see. A provincial referendum to make DST permanent failed in Alberta last year (49.9% in favour to 50.1% against).

@jlokier 3 months

I'm surprised at the number of commenters who think permanent DST is favourable to night owls and bad for morning people.

I think it's night owls and delayed-cycle teenagers attending school who will suffer most under permanent DST.

In the Winter, permanent DST means everyone has to get up an hour earlier for work or school's clock time, relative to the sun which regulates their body rhythm.

Someone pointed out virtually nobody sets when they wake by the sun. Fair enough. But the sun does affect how well and how long they sleep, how restored they are, how they feel when they wake, and energy and concentration through the rest of the day.

Night people already struggle with getting up early enough for clock-time social expectations. As it's a struggle already, getting up an hour earlier is going to be harder for them. (If the sun makes no difference, why is it already hard?)

Research (e.g. https://news.ycombinator.com/item?id=30691158) suggests that overall, health will suffer, sleep will be shorter, and educational attainment in teenage years will reduce. Even brain development may be adversely affected.

But there will be more shopping (economic activity), so that's ok.

Watching Americans freak out about post-8AM sunrises is surreal to me. The sun doesn't rise until 8:45 during the darkest times of the year here in the Netherlands and its really not much of an issue.

Whether standard time or summer time is the better choice here is something I hold no opinion on, but the sheer hysteria some people here express is very overblown.


@sporkland 3 months

Trying to analyze the impact of this I used my favorite tool for thinking through DST issues: https://www.timeanddate.com/sun/@z-us-94114

Seems like with this law in effect, near the winter solstice in San Francisco what would have been 7:21am - 4:54pm will now instead be 8:21am - 5:54pm day light hours. Is this accurate?

On the one hand, the 6pm night time feels pretty reasonable, but 8:20 for sun in the morning seems pretty early. Although I think I prefer this to having standard time year around.

My favorite option on this topic is to change the clocks smaller amounts way more often to try and achieve good alignment between clocks and day light. I haven't worked it out with precision, but it seems like it should be better than than these hour jumps or not jumping at all.

Making DST permanent is essentially forcing everyone to wake up earlier in the day. All we're doing is calling 7 am, now 8 am to get people to psychologically accept this. This is a win for morning people who function better earlier... AND this is a loss for all the non-morning people who will now be forced to work, go to school, etc at a time when they don't operate optimally.

@jackjeff 3 months

I really hope the UK does not imitate this. I moved from France to the UK over ten years ago. According to geography, France and the UK should be on the same time zone, but in practice France is using Germany’s time zone. In France thanks to the perfect combo of DST and the wrong time zone, you’re permanently shifted by either +1 or +2. The net effect is almost never see the sun in the morning when you wake up if you have to abide to standard office/school hours. When I moved to the UK I realised I was much less tired and happier to just wake up with the sun (at least for part of the year).

@wolverine876 3 months

The whole world going to the same time zone, usually proposed in these discussions, doesn't work - sun-time dissociates with clock-time, making words like "night" and "noon" confusing.

However, I would like to see a North American Standard time (NAT): Set the clock at half-way between US Mountain and Central times and apply it to all of North America (with maybe a few extreme exceptions, such as western Alaska and Hawaii). The coasts would be off ~30 minutes more than DST, which I hope isn't too far, and nobody in North America would have to think about time zones again.

Sunlight is one of the most powerful zeitgebers and it makes sense to try and optimize the amount of sunlight exposure. However, is there a difference between morning light and evening light in terms of how they entrain the circadian rhythm?

If I work from 9am to 5pm in a dark office building, permanent standard time might allow me an hour of sunshine before work from 8am to 9am, and permanent DST might have me arriving in work while it's still dark but allow me an hour of sunshine from 5pm to 6pm. Which of those light exposure patterns would allow me to wake up easier at 7.30am?

I'd kill for a peek into the parallel universe where it was permanent standard time that was likely to get adopted and see how much effort went into researching the ill effects of that choice to convince people with enough FUD to keep daylight time switching going.

Here's the thing: If you're a proponent of permanent standard time, you should be in favour of turning off the switching no matter what. Even if it means daylight time. Because you know what? Your local time zone is changeable. You can lobby to change it. If permanent DST really results in the entire country turning into sleep deprived zombies having spontaneous heart attacks as they arrive at work and crashing into children going to school, then there'll be pressure to change it -- but we will have at least already started the process of eliminating the worse thing: changing twice a year.

Wrong move (again). The correct move would have been to make standard time permanent.

We tried permanent DST in the 70's and it was all well and good until people realized it meant complete darkness at 9am in winter.

Let's see if people will feel differently this time around (they won't).


@captainmuon 3 months

This is ridiculous. Why don't they make the regular time permanent? And if people want to have more light in the evening, then they just leave work earlier. Surely that is easier than permanent daylight savings time.

I know people will say it's too hard to change habits and (clock) work hours, but with permanent DST you will have to change that anyway, when people realize how dark winter mornings will be. I predict a lot of people will want to move school start to a later hour then.

This is the stupidest thing I've ever seen. There's a reason why "Standard Time" is called that. Now the words "Midday" and "Midnight" are meaningless.

The measurement of time is a science, and science should not be decided by politicians.

This seems trivial, but if this, then what next?

Edit: I'm getting a lot of replies saying that "midday" isn't precisely the middle of the day, and therefore I am wrong, but even since the invention of timezones, midday is supposed to be "the middle of the day, to the nearest hour". Now it is intentionally skewed, and keeping this forever seems like a huge mistake.

If you are willing to accept that the numbers on the clock don't actually mean anything, we should all just use UTC all the time, with all the pain that that will bring. This is just the first step along the way.

He responded this code was temporary and it would be gone by then.

There was another PR on a certain Monday a few months later. Told ya so.


@dathinab 3 months

Sometimes the ignorance of lawmakers is just baffling.

I mean there is pretty much a scientific consensus as far as I know that switching to permanent DST is a quite unhealthy choice for the larger part of the population, which happen to already be negative affected by other effects also balanced against them.

Just to be clear I don't know if it's worse then DST switching.

But it's worse then permanent "normal" (i.e. winter) time.

I mean there is a reason this was the normal time, before DST was introduced.

I also want to note here that for some areas in some time zones the negative effects of permanent DST might be less then for other areas (potentially) in other time zone, idk. how this applies to the US.

Everyone wants more money left over after they buy something, so the obvious way to achieve that is just slide all the numbering systems left by one.

Henceforth all prices shall be written on a scale that starts at -1 instead of 0. If a thing cost $4 yesterday, it now costs the same 4 dollars, but the price is written as $3. This will give everyone more money!

Why don't we leave the clocks aligned with the Sun, so noon occurs at solar noon, and just have everybody agree to shift their work day to 7:00 to 4:00.

Because on a solar basis, that is exactly what you are doing. "8 to 5" will now be "7 to 4". And people that normally work "7 to 4" will now be working "6 to 3"

That is all you are doing. You are basically just kidding yourselves. It is so extremely stupid, really. You want more sun in your evening? Get up and get to work earlier. It isn't rocket science.

I'll be waiting two years out for everyone pushing the school day to start at 10:AM, and for a lot of businesses to start at 9:AM instead of 8.

You could solve all these problems by just getting the Networks to stream their programming one hour earlier at night. And leave the clocks on standard time year round.


@patwolf 3 months

Back in '08 when the US dates of DST changed, I was working on a Java-based enterprise software product with a relatively large install base. It suddenly became known to a lot of customers that timezone tables are part of the JRE, and simply updating the OS wasn't enough to get proper time calculations in Java. It was a very stressful time getting customers with many different versions of Java across dozens of platforms properly updated. A lot of customers were running ancient versions of Java that were well past EOL, but we still helped them out.

Needless to say, I'm very happy this might finally happen. I do not, however, envy whoever is now supporting that software. I'm sure there are folks that haven't touched their systems since the last DST change.

The problem with daylight savings is that people generally go to bed later, because the sun influences what time we feel tired. For adults with a flexible schedule this may be OK, but for children it is a disaster, as their school start time does not change.

India is basically doing this experiment in real time with their one-time zone policy. Children on the west do worse from an educational standpoint because the sun sets later, yet school starts at the same time.

This was widely covered in the news a few years back.

This will probably get lost, but anyway.

Socially we need a way to synchronize with each other and we designed our culture around calendars and clocks, synchronized to Earth revolutions - midnight.

Our bodies are designed (evolved if you want) to synchronize with the sun and there the best (healthiest) waking time is at sunrise. When synchronized to midnight, sunrise time varies and that variation depends on latitude.

It is simply preferable to have waking time synchronized with the sunrise. DST is one way to do that and actually quite good: it keeps clocks universally synchronized around the world allows scheduling not to consider sunrise time variations.

this is the best news i've read on hacker news for some time.

it's time to standardize our time.

All these arguments about school times etc. My code would be eternally ridiculed if I mocked the Date object to artificially change the time, instead changing the time school started for certain months.

This is excellent. With the rise of air conditioning, daylight savings has considerably less electricity savings than it used to. It will also make timekeeping more consistent. I have lived in Arizona for the past few years and it is pleasant to know that you will always be at UTC-7:00.

I mentioned something similar in a comment last year, but I think there's going to be a lot of moaning about late sunrises in US in December. Roughly 8:15-8:20 am around the solstice in New York, DC, Chicago, and even Austin. Not til nearly 9am in Seattle. The sun won't rise before 8am in NYC for basically all of December and January.

I'd even be willing to guess that the amount of moaning might be equal to what we get now around the clock change.

Since apparently no one likes changing the time but no one can agree whether we should go with standard or daylight time, why don't we just split it right down the middle and have an extra 30 minutes added to our UTC offset like in India?

The country of Elbonia passes the bill for the "moon bashing act" and permanently forward the clock by _12_ hours (and not just a laughable one hour), after Elbonien scientists discovered that the cost savings for street lighting alone is equivalent to half of their gross domestic product.

... and i will adjust my clock dynamically, so i'm never too late again.

We did this before, about 50 years ago. Going in, close to 80% of people supported permanent Daylight Saving Time. After experiencing a single winter, that dropped to close to 40%, and it was repealed. Looks like we may be doomed to repeat the experience.

Studies have shown that later sunsets lead to worse health and economic outcomes. People who live on the western edge of a timezone earn 3% less and have higher rates of lifestyle diseases than those on the eastern edge, because they go to bed later but wake at the same socially-prescribed time, and therefore get less sleep. [1]

So why make DST instead of eliminating it entirely? It seems earlier sunset would be much more beneficial for society.

Yes. Save the sun, save the lights, save everything.

Will some states get new timezones that meet their DST needs in response to this?

Mods: Maybe the tweet link could be replaced with this Reuters article: https://www.reuters.com/world/us/us-senate-approves-bill-tha...

> WASHINGTON, March 15 (Reuters) - The U.S. Senate voted unanimously on Tuesday to make Daylight Savings Time permanent, a move supporters say would make winter afternoons brighter and end the twice changing of clocks.

> The measure still needs approval from the U.S. House of Representatives and the backing of President Joe Biden. On Sunday, most of the United States resumed Daylight Savings Time, moving ahead one hour. The United States will resume standard time in November 2022.

> Senator Marco Rubio said after input from airlines and broadcasters that supporters agreed that the change would not take place until November 2023.

(I searched around after seeing the @senatecloakroom tweet, but apparently the news was new enough that no articles had yet been written)

What do we think about the impact on our software? I have no clue about how my OS deals with TZ info changes over time or how older systems would behave absent a centralized management system.
