Should America Stop Changing Its Clocks?

Why can we not just leave the time as it is and just adjust to the changing hours of the day? I would not mind if the time was left as Daylight Saving Time and then not changed again. I do like the idea of having more time in the evening to do things.

Please let's kill DST.

I'm also a supporter of the far more radical proposal to switch to a Universal Standard Time (i.e. 10:00 in NYC is 10:00 everywhere, 14:37 (currently 2:37pm) in Beirut is 14:37 in Moscow is 14:37 in London, UK and London, Ontario.) We'd no longer need an international date line because we'd all be at the same time on the same day. If we, at the same time, truncated the last hour of the day, we could eliminate leap-years too.

But, yes, let's start with killing DST.

different areas would have different ideas about 10:00 - for some countries it would be daylight and others night. For some dinner time and for others bedtime. Maybe it would be better to have the differentiation on that side rather than have the actual time be different.

So you work from 8am, but where you are that 8am used to be 3am. You'll go to work in the middle of the actual night, get off in the middle of the actual morning. You really think you're going to go to bed and get a good amount of sleep if you have to do that when it's several hours before nightfall?

People are reasonable tuned to the light and dark rhythm of the natural day. DST is a one hour shift, and I happen to like it, I just wish DST didn't start quite so early or end so late.

If you used to go to work at 8am EST and get out at 4pm EST...you'd probably continue going to work at the same time of day as it always was, it just would be a different time on the clock than it used to be. If we used UTC...it would be 13:00-21:00 UTC. It would still be daylight hours, just a different time than it used to be.

Did you really think if we went to UTC that everybody's work day would begin and end at the same time as it used to? That means something like 4B people all working the same 8 hours of the 24-hour day. That's some sort of dystopian nightmare.

Let's just stick to the time zones we have now, so that it's not very confusing.

And yes, I did interpret the putting the whole world on the same time as everyone would conform to that, and you're right, it would be a total dystopian nightmare.

If people complain so bitterly about the shift between standard and daylight time, they would NEVER stop complaining about a permanent reset of the clock. Right now it's about 2:30 in the afternoon, and I would not want this time to be 2130, because to me 2130 is 9:30 at night.

What in the world do you do if you go on a trip that has you crossing a time zone or two?

Arizona doesn't do DST because it's so god-awful hot all summer in most of the state that no one is going to be outside enjoying nice weather, so there's not point in it. It does get light far too early all summer, for what my opinion is worth. I've lived in Arizona two different times in my life: in the 60's so I was there the one year (1967) they did DST, and later in the 1980s. Personally, I cannot abide the kind of heat they have there.

It's one of the 2 or 3 largest causes of insomnia as it disrupts the circadian rhythm. There is also a correlation to work-errors increasing around the two clock-changes, an increase in heart attacks and a suspected connection to the onset of certain cancers.

Driving across time zones doesn't bother me too much since it is not terribly efficient, flying many time zones to the west doesn't bother me too much either provided I stay up until local bedtime comes, going the other way is a pain in the ass.

As indicated in several responses to the OP, I am not alone in reacting badly to the transition (the spring switcheroo is much worse than the fall one). And I thank you for your concern.

Sat Mar 12, 2016, 10:40 PM
Mar 2016

Time zones, and even international travel, don't bother me so much because then I'm usually on vacation and even if I'm working, I usually have more leeway with time and it won't be for more than a few days anyway. But day to day? I've been dreading tonight, for instance, for the last month.

It's just awful, and it's more than a simple inconvenience. It leaves me with headaches, confusion, muddy-headedness. Have you ever had a period of extreme depression? It's like that, except I'm already depressed, so changing the clocks and fucking with my circadian rhythm (for no good reason) just exacerbates it.

I suspect it may have something to do with Seasonal Affective Disorder and other related medical issues.

Stay on standard time the year aground. There is a reason it is called Standard Time.
Switching the clocks screws with our internal clocks, which is detrimental to our health. And Daylight Savings Time does not save any energy. In fact the opposite occurs. More energy is used because of air conditioning.

The buses in many school districts run two or three different routes - in my school district, the high schools go first, then the elementary school, then the middle schools.

Also, an early start in high school allows more time for students to participate in after school activities and work, while still having time for homework.

its the arbitrary and artificial change that is so disruptive

http://www.livescience.com/40903-daylight-saving-time-affects-your-body.html

1. More car accidents?

An increase in car accidents during daylight saving time has been both supported and refuted in the academic literature. The general concept supporting the case, however, is that subtle changes in sleep patterns and circadian rhythms can alter human alertness and, in some cases, might increase the risk of potentially fatal car accidents.

Still, one 2010 Journal of Environmental Public Health study that analyzed the number of traffic accidents in Finland one week before and one week after transitions into and out of daylight saving time from 1981 through 2006 found no significant change in the number of accidents during this time period. Another 2010 study published in the Journal of Safety Research found that daylight saving time can actually result in fewer crashes by increasing visibility for drivers in the morning.

2. Increased workplace injuries

Though this threat may not apply to those who work in the relatively padded confines of carpeted office buildings, others who work at more physically taxing jobs, such as miners, have been shown to experience more frequent and severe workplace injuries at the onset of daylight saving time in the spring. The effect has not been detected at the end of daylight saving time in the fall.

The 2009 Journal of Applied Psychology study that came to this conclusion found that mine workers arrived at work with 40 minutes less sleep and experienced 5.7 percent more workplace injuries in the week directly following the springtime daylight saving transition than during any other days of the year. The researchers attribute the injuries to lack of sleep, which might explain why the same effect did not pop up in the fall when workers gained an hour of sleep. [Top 10 Spooky Sleep Disorders]

Body's Clock Never Adjusts to Daylight Saving Time
http://abcnews.go.com/Health/Healthday/story?id=4509150

WEDNESDAY, Oct. 24 (HealthDay News) -- Changing to daylight saving time may give people an hour more of sunlight, but it appears that their internal body clocks never really adjusts to the change, German researchers report.

In fact, daylight saving time can cause a significant seasonal disruption that might have other effects on our bodies, according to the report in the Oct. 24 online edition of Current Biology.

Sat Mar 12, 2016, 10:38 AM
Mar 2016

I think people have confused that they feel worse during most of spring, summer and autumn, with a change in the clocks. Of course a study in Central Europe can find people's waking-up time doesn't track sunrise in summer as well as it does in winter - because it becomes too early for them. In winter, later sunrises make your body want to stay in bed later. They didn't do an experiment with the people living through a summer without DST.

Yes, there are effects at the time of change - but they don't last 7 months. The natural signals of light and temperature mean that the body never keeps a precise 24 hour cycle through the entire year, and the idea that your body hasn't made the 60 minute adjustment after 200 days, even with light and temperature varying by more than an hour in that time, is absurd.

In fact, daylight saving time can cause a significant seasonal disruption that might have other effects on our bodies, according to the report in the Oct. 24 online edition of Current Biology.


For both morning larks and night owls, their timing for sleep and peak activity easily adjusted when daylight saving time ended in the fall. However, it never adjusted to the return to daylight saving time in spring. This was especially true for night owls -- those who stay up late and sleep late.

"If we didn't change to daylight saving time, people would adjust to dawn during the summer and again to dawn in the autumn," Roenneberg. "But this natural adjustment is interrupted by daylight saving time," he said.

Personal , anecdotal and experiential bias do not change the out come of the studies (admittedly like all studies they are narrowly defined). The studies confirm this; there do not seem to be any studies that refute the assertion. The studies identify the time changes associated with DST as the culprit (more specifically the body's inability to deal with the artificial and arbitrary change in sleep wake patterns associated with the time change).





http://phys.org/news/2015-10-daylight-linked-injuries-heart-scrap.html

While the clocks on most digital devices update automatically, transitions into and out of DST can be difficult for us humans. And a number of recent studies are providing insights into how a solitary hour can inadvertently affect our health, mood and productivity – often in a negative way.
Effects on human health
In 2008, researchers examined the influence of these transitions on the incidence of heart attacks across several years of hospital admissions data. They focused on the two weeks before and after the clocks changed. Worryingly, they found a spike in the number of reported heart attacks after the transition to DST in the spring. In contrast, after moving out of daylight savings time in the autumn this trend was reversed.
These patterns were more pronounced in patients who were of working age (under 65) and the authors argued that the effects may have stemmed from the negative effects of sleep deprivation on cardiovascular health. They also suggested that vulnerable people should avoid other rapid changes to their sleeping patterns similar to those experienced as part of DST.
Transitions into and out of DST have also been associated with road traffic accidents, workplace injuries, poor mood and reduced efficiency. And many of these effects have been attributed to changes in sleep duration. The effect is likely to be magnified even further as many people are now regularly sleep deprived – the average sleep duration has fallen from nine to 7.5 hours during the 20th century.

Conclusions
The early March DST onset adversely affected sleep and vigilance in high school students resulting in increased daytime sleepiness. Larger scale evaluations of sleep impairments related to DST are needed to further quantify this problem in the population. If confirmed, measures to attenuate sleep loss post-DST should be implemented.

Background

Daylight saving time (DST) is commonly used worldwide and affects millions of people annually. It equals to one-hour time zone crossing eastward in the spring and westward in the fall. In the European Union, DST currently begins on the last Sunday of March, when the clocks are turned forwards by one hour, and ends on the last Sunday of October, when the clocks are turned backwards by one hour. The rationale for DST is to improve the match between the daylight hours with the activity peaks of a population. Fall transition out of DST increases the available daylight in the morning by one hour. Spring transition into DST leads to an increase of the available daylight in the evening. In our previous studies, we found that transition into daylight saving time may disrupt the rest-activity cycle in healthy adults [1, 2]. Herein, our aim was to assess the daily rest-activity cycles together with night-time sleep at transitions out of and into daylight saving time in healthy adults. Our goal was to find out whether the changes induced by transition into DST were similar in fall and spring.

Results

Fall: before versus after transition
The movement and fragmentation index (P = 0.01; Z = -2,52) was increased in all the participants after the transition (Table 1). Sleep efficiency (P = 0.02; Z = -2.38) and relative amplitude (P = 0.02; Z = -2.43) were reduced in all except one participant after transition.

This sub-thread has developed because a DUer said that, even 7 months after changing to DST, they are still not feeling right, but they do feel right once the clocks go back to standard time.

That is something I have never heard anyone say before, and the studies do not show it.

.... in the sub thread, the DUer reports that they live in an area that did not institute DST until they were in their thirties. i would imagine that has played into their difficulty adjusting. The studies do show that their is a continuum and individual ability to adapt.

Although I do "adjust" .... my internal rhythms are not in sync with DST .

to crossing time zones, which strikes me as total nonsense.

The usual rule of thumb about adjusting is one day for each zone you cross. So people saying that they just don't ever adjust, even over months, to the switch between ST and DST is nonsense.

Are you saying that people moving to a new time zone, twice annually, all adjust completely... I would guess that if one moved to a different time zone with the frequency of the time changes with DST (beginning and ending) the result would be the same for the individual.

I don't think you read any of the articles and studies ... people adjust but to varying degrees. I have no problem believing those that say they never completely adjust ... I think that would be true of me ... I generally require an alarm from spring to fall ... and don't even bother setting an arm from fall to spring. This is anecdotal proof that I have never completely adjusted.

goes away pretty quickly, as does the disruption when someone crosses time zones. Otherwise the best way to run the planet would be for no one to move, ever. Or to ever take a trip that requires crossing a time zone.

What if you simply have to get up extra early one day because, say, you're catching an early morning flight? Don't you recover from that particular shortage of sleep in a couple of days?

Personal and anecdote experience really mean nothing .... so again I ask where you are going with this?


What if you simply have to get up extra early one day because, say, you're catching an early morning flight? Don't you recover from that particular shortage of sleep in a couple of days?


If you think abut it, the above is not comparable. A situation that would be comparable would be a change in working hours that occurred twice yearly (e.g. a work start time at 8:00AM changing to 7:00AM (or 9:00). In that case I would expect to see the risks to the individual being similar to those noted for a population in the DST studies. That does happen all the time and individuals face increases in risk of bad out comes vs populations experiencing that risk.


It would be really interesting to read the results of studies that refute the studies indicating that there adverse effects on people associated with the time changes.

isn't that huge, even though it's real, and to what extent the change of the clocks is truly responsible isn't totally clear.

As for changing work times, that does happen to people. In the Kansas City area, where I used to live, a number of companies had special summer hours, where people came in an hour earlier and got off at noon on Friday. I haven't worked one of those jobs, and I'm not sure I'd want to.

Admittedly, I'm not much of a morning person myself, and much of my working life I held an afternoon shift. I almost always got enough sleep, which is really the issue. Most people are chronically sleep deprived and just don't recognize it. People take great pride in only sleeping x number of hours a night, and then wonder why they never feel terrific, or why they catch every little thing that goes around.

I just think people are making a huge big deal out of the switch between standard and daylight time that's unwarranted. Or maybe I'm the only person in North America who likes the change, except that if it were up to me DST would start in the middle of April and end at the end of September. But I'm not in charge of that.

Which is why it was called Standard Time. If we are going to be on Daylight Saving Time most of the year, then the time used during the winter should not be called Standard Time anymore. Because it isn't. Not when we are on it for only a few months. I agree that we should stay on one or the other and stop switching back and forth. I could live with either one.

Sat Mar 12, 2016, 12:29 PM
Mar 2016
On Monday August 8, 2005 President Bush signed into law a broad energy bill that extended Daylight Saving Time by four weeks beginning in 2007. Since 1986 the United States had observed Daylight Saving Time from the first Sunday in April through the last Sunday in October. The provisions of the bill call for Daylight Saving Time to begin three weeks earlier on the second Sunday in March and end on the first Sunday in November. Read our special section about the extension of Daylight Saving Time.

http://www.timetemperature.com/tzus/daylight_saving_time.shtml

It's called 'standard time' because it has the sun at its highest point, due south, at noon in the middle of the zone. This matches with Greenwich Mean Time, based on the position of the sun at Greenwich, the origin for international longitude.

I eventually adjust but it takes weeks


Body's Clock Never Adjusts to Daylight Saving Time
http://abcnews.go.com/Health/Healthday/story?id=4509150

WEDNESDAY, Oct. 24 (HealthDay News) -- Changing to daylight saving time may give people an hour more of sunlight, but it appears that their internal body clocks never really adjusts to the change, German researchers report.

In fact, daylight saving time can cause a significant seasonal disruption that might have other effects on our bodies, according to the report in the Oct. 24 online edition of Current Biology.

edit to add:

For both morning larks and night owls, their timing for sleep and peak activity easily adjusted when daylight saving time ended in the fall. However, it never adjusted to the return to daylight saving time in spring. This was especially true for night owls -- those who stay up late and sleep late.

"If we didn't change to daylight saving time, people would adjust to dawn during the summer and again to dawn in the autumn," Roenneberg. "But this natural adjustment is interrupted by daylight saving time," he said.

Reading through the studies there is a continuum of adjustment (i.e. some people adjust quickly with little adverse effect and some adjust poorly or never quite adjust).

Anecdotally, it takes me a couple of weeks to adjust to each time change.

My objection to the time changes is that there is no relevant interest in changing the time in a society that functions around the clock (we can shop, go out to eat, work, take classes 24 hours a day). I don't care which time we choose .... just pick one and stick with it. We don't save energy, increase business, enhance lifestyles by making the arbitrary change.

Going to work in the dark isn't so bad - IF you drive a car or have good access to public transportation.

That's not the case for everyone. I ride my bike to work, over an hour commute each way. Riding in the dark is stressful and more dangerous. Most accidents occur in the day - because most bike rides happen during the day. But most fatalities occur at night.

Even without drivers trying to kill us, it's a lot harder in the dark to see potholes, whether something is a puddle or black ice, if it is a puddle we can't see what the pavement beneath the water looks like, we have to account for reaction time when our light only shines X number feet to illuminate what's in front of us.

Scandinavian countries may fair better with their higher rates of bicycle riders; drivers are more used to seeing bikes on the road.

Pedestrians have similar safety problems getting to work in the dark (not so much outrunning their headlights, but getting hit by drivers).

I think that mucking with daylight savings time simply plays into the hands of rich, greedy assholes who are constantly looking to squeeze a little more profit and productivity out of the slave-wage drone fleet. They want you to drive to work in the dark, work all the daylight hours so that they pay less for electricity, and drive home in the dark, so that you, the slave-wager, pay for your own lighting and heat and they don't. That's how it already works in winter.

If we adjust our daylight savings time schedule, they'll simply change the work schedule so that you continue to get screwed in the winter, only now your biological clocks will be at the mercy of your unempathetic employer instead of our unempathetic government, so you may enjoy a period of having to come in 15 minutes earlier every two weeks in the spring, for example, and the opposite in the fall.

Factor in the now well-documented fact that high school kids become more stupid (and therefore more Republican) the earlier they go in to school, and it's obvious to me that there is no solution which will not be malevolently exploited by our keepers. Show me a solution that works for average humans instead of their overlords, and I'll be all for it. I don't think there is one.

It's just ridiculous. The stereotypical workday begins at 9 and ends at 5. Take a look at that. Just three hours of work before noon followed by five hours afterwards. Presumably to make it easier to get to work. But then, to get in 8 hours, you have to run all the way to 5, leaving little daylight after work. What to do... What to do... Yeah, lets change the clocks so that in effect you start the work day at 8 and end at 4. That's the ticket!
