Is Daylight Saving Shift Really Worth It?

Waffle Iron (339739) | more than 7 years ago | (#18314941)

This change in DST was definitely worth it, if only for the benefit of forcing embedded systems designers to remember to not hard-code DST dates into their code. Historically, these dates have been changed about once per decade in the US alone. Assuming that they'll never change again is plain stupid. This shift will help train the current generation of developers to just not do that.

EggyToast (858951) | more than 7 years ago | (#18315055)

It shifts all the time. It's even slowly moved westward as cities on an eastern time zone border have pushed to get lumped into the next time zone. Why? Because the vast majority of businesses aren't flexible in their staffing hours and people can't choose to simply go in when they wake up.

My wife says that she wishes DST was all the time, as she has no problems waking up in the dark but tends to work long hours and we regularly stay up until 11 or 12.

And yeah, as a reminder to programmers it's great, but it's also great for all people to realize that time is abstract and can pretty much be whenever. I don't think I've ever heard an elderly person lament the time when we were all standard time.

Re:Already spending money? (5, Funny)

cooley (261024) | more than 7 years ago | (#18315109)

Is DST WORTH IT? Boy, Let me tell you a story about the place I come from.

I live in Indiana (a midwestern US state). Up until last year, we'd never done DST before at all (with a few exceptions in towns whose economies were linked to cities across the border in other, DST-observing states).

Before we had DST, it was HELL. All year, it got dark at like 2:00pm. There was no Little League Baseball, no football (american or otherwise) for the kids. Most of our youth joined gangs, who roamed the incessant darkness in large, heavily fortified bad-mpg SUVs, kicking puppies and beating up old ladies just for fun. There was no Christmas and no birthdays, and if we saw the Easter bunny we ATE HIM.

Though many people had the misconception that we were "America's Breadbasket", in fact the darkness prevented us from raising any sort of sustenance crops and most of us resorted to cannibalism to survive. Most Hoosiers (that's what we're called, it means "land of eternal darkness" in a Native American tongue) eventually starved to death, which was viewed as a welcome respite from the hellish, unstoppable night. Dogs and cats, living together, you get the picture.

Then, we elected a new Governor who brought us into the light (literally). With the introduction of DST, and the seemingly random (almost whimsical, really) distribution of our Counties between two time zones, our lives were changed forever. Now, it's light outside pretty much twenty-four-fucking-seven. Our kids are all on at least six sports teams and never shoot each other anymore. They call you "sir" or "ma'am" (these words were not used before, as it was difficult to discern gender in the darkness), shine your shoes for you, and present you with ice-cold lemonade from stands with amusingly misspelled signs. We discovered oil everywhere, we grow more crops than the world could ever possibly use (which has ended hunger globally) and we're all filthy, stinking RICH. All the women have big perky boobs, all the men are RIPPED, and everybody has an IQ of at least 160.

Yes Sir, I don't know what we'd do if it weren't for good ol' DST. I have to assume that with the new DST-extending rule from our good friends in the US Congress, we'll probably just evolve to a higher state of being and shed these silly, out-dated husks to become super-intelligent beings composed of pure energy.

If without daylight saving time it was dark by 2pm, then unless it was also not light until 10am (which unless you are close to either the Arctic or Antarctic circle is very unlikely) then you are in the wrong timezone. In the correct timezone, there should be approximately equal periods of light either side of noon.

The days of going to work in the dark and leaving in the dark weigh heavy on the soul/psyche. DST is a big boost, IMO.

But that has nothing to do with DST, that has to do with 1) what time you come and go to work and how long you stay there, and 2) the days are simply shorter in the winter because the Earth's axis. In extreme Northern and Southern climates (think North and South polar regions), its daylight and dark 24 hours a day depending on the season, and changing the clock will not change that.

I heard on NPR the other day, that the _real_ reason for DST is not to save energy, but rather to appease the retail sector. They have data that people are more willing to go out and spend money after work if its not dark. So people go motoring around in their fuel efficient SUVs, blow money, and thus energy is saved!

Personally, I don't understand why humans are so clock oriented vs sun oriented. It kills me that houses in the US are built in random directions (unless there is a nice view) instead of oriented around the Sun.

Sometimes I think humans are the silliest of all animals.

I'm in 100% agreement. It might not do anything for energy consumption but it sure does make me a happier camper! I work from 9:30 to 6 and while for the last three weeks there has been some light when I'm driving home, it's going to be REALLY nice to have an entire trip with daylight. Not only do I feel better and happier during the light hours, I also feel safer because everyone else around me is driving in the daylight too.

I take a camping trip at the end of March every year and it will be SO nice to have that extra hour of daylight to get camp setup, cook dinner, and enjoy the park.

While I don't agree with nearly everything Bush has done, even though it's possibly for the wrong reason, this one is a good thing.

BigDogCH (760290) | more than 7 years ago | (#18315131)

I see your point, and I like it when you are a happy camper, but daylight savings does NOT change how many hours of daylight we have at our disposal.

I repeat DAYLIGHT SAVINGS TIME DOES NOT GIVE US MORE DAYLIGHT. It does not change the planets tilt, rotation speed, or smell.

Sorry, but it just bugs me when everyone claims it gives us more daylight. DST should be abolished altogether. Any companies that want to change their business hours for the seasons should do so on their own. Factories in the Midwest, like mine, start their employees 2-3 hours earlier in the summer so they can avoid the heat of the day. DST just means now we have to start our employees 3-4 hours earlier to avoid the heat.

DST is my new mortal enemy.

So what if an early DST doesn't really have huge enery savings? Of course, this is a research paper by 2 students at the People's Republic of Berkeley, who no doubt must be the most completely objective sources on the planet. (sarcasm off) There are benefits such as being able to actually go outside and get some exercise after work or do yard work because it's not too dark, being able to drive home after work in daylight and so on.

Why don't they just pass a law stating that for purposes of the government, standard work hours are shifted +1/-1hr within a given time period, and encourage private industry to do the same? That way you get your ability to drive home in daylight, and I don't have anyone screwing with my clocks.

(For that matter, if it's that big of a difference, why doesn't private industry decide to change business hours independently? Personally, I don't see it as a big enough change to be worth bothering -- but then, I exercise in the mornings rather than afternoons, and have an employer who allows me to shift my hours at will).

The office light, the bathroom light & fan, as well as the bedroom lights do not see any less use in summer mornings than they do in the winter. The only light affected by all of this is the kitchen light. For the evening routine, there will be more lights that are delayed by an hour than the kitchen light that was extended by an hour. Think of exterior lights too. They are timed to come on in the evening but don't come on in the morning. So far, so good.

I live in Western Australia, and we're currently running a trial of Daylight savings. It's all well and good for those of us in the lower half of the state, where there is an appreciable difference in the sunset/sunrise times Summer vs Winter, but at the top of the state nearer the equator, it must be annoying at the very least.

(Not to mention it's hot enough that the airconditioning will be on wherever I am, daylight savings or no, so I doubt there's much of an energy saving there either)

Re:It's dependent on where you live (2, Interesting)

Anonymous Coward | more than 7 years ago | (#18315197)

Exactly. Congratulations on being (so far) the only reply that mentions distance from the equator.

Your distance from the equator and the season are the two critical factors. If you live far from the equator and it is closer to the summer solstice than the winter solstice then you have 'daylight to spend'. Where should we spend it? In the evening, or in the morning? Most people don't have any interest in getting up earlier than 6:00 AM, so shifting those wasted hours of sunlight to the evening makes sense. It also makes it easier to sleep in to a decent hour.

Trying to apply a study in Victoria, Australia to North America seems silly (disclaimer: the ABC news story didn't list full details of the study). Melbourne, Victoria is only 37.7 degrees from the equator, and most of the state is even closer. So, they don't get much change in day length, compared to the probably 60% of the continental US that is farther from the equator than Melbourne. Don't get me started on Alaska.

The problem with the DST change is that it now starts when we are still in a sunshine deficit. In the Southern states the days are still about half sunshine, as always, and in the Northern states the days are still noticeably less than half sunshine, so we're spending our excess sunshine hours when we don't have them.

I like DST because I'd rather have daylight in the evening than in the morning--I rarely get up before 7:00 AM. And, I like having DST earlier because I like to bike to and from work and since I ride in around 9:00 AM and return around 5:00 AM it works better for me if the sun is at its peak halfway between--around 1:00 AM--which is what DST does.

However, it seems unlikely that there would be much if any power savings for the next three weeks of DST where we are robbing Peter to pay Paul, and Peter doesn't have much to start with.

Anyway, this is a long-winded way of saying that discussing the usefulness of DST without specifying a distance from the equator is pointless. There's a reason that tropical countries (including New Mexico :-) don't generally use DST.

The obvious answer is that congress needed an easy way to put something down on paper that they care about energy policy.
Was there any in depth hearings on it, any experts called in to testify on the change, any representatives from industries affected by this change, actual debate on the subject? As far as i can remember, it was no on all accounts.

Congress passes a law without knowing the full consequences, simply so they would have something to show in the 06 elections.

It doesn't matter if people adjust their personal schedules, what drives most peoples schedules are the hours they have to be at work. Only when the gov't dictates a change will their be a change in schedules. I generally hate big gov't getting involved with the normal lives of the people, but sometimes, just sometimes, something good happens.

More driving? (5, Interesting)

Lurker2288 (995635) | more than 7 years ago | (#18314961)

According to, a gas price bump is expected now because people are expected to drive more with the expanded daylight hours.

So wait, Washington passed a law to change DST early...the early DST change is now being used to justify gas price increases? Coincidence? Happenstance?

Sorry all, maybe my TFH is a little tight this morning.

That happens every big surprise and certainly not evidence of any kind of conspiracy. Welcome to "summer". People hybernate all winter and when the weather starts to turn pretty again, they come out and do things. That means they drive more, gas demand goes up, price goes up. Simple rule.

Re:More driving? (1)

falcon5768 (629591) | more than 7 years ago | (#18315285)

no the conspiracy comes in the fact that we have more than ample supply to meet demand and thus the prices shouldnt go up, but do, this year expecting to be worse than even after Katrina. And that a good 60-70% of our government (Republican and Democrat) has their fortunes tied to that price going up.

THATS where you sit back and say "hmmm somethings not right here."

The other side (3, Interesting)

Spackler (223562) | more than 7 years ago | (#18314967)

Ok, I am going to argue the other side of this.

From TFA:
But Ryan Kellogg and Hendrik Wolff, who are working on their doctorates in economics, say the reduced need for light in the evening will likely be negated by the increased need in the early morning.

That sounds logical, but it is not (IMHO). In the morning when I get up for work, I turn on maybe two lights (bedroom and bathroom). I am focused on getting ready for work, so there is not any entertainment (TV), stereo, really nothing except an electric razor. I brew my tea, and I am off to work (I don't think my headlights count as extra energy).

When I come home from work, well, all the lights in the kitchen, the halls, very soon the livingroom, the plasma TV, the surround sound, the computer. Lot's more things. Now, most of these don't change from summer to winter, except the lights. If it is light out, I do not turn them on (shocking). That is a savings of energy by not turning on the lights.

I really don't think this article took into account the different energy needs from the morning to night times. It is short sighted.


(ok, the gate is open for you to disagree, but really think about the way you do things different in the mornings and how most people do it different first)

Re:The other side (2, Interesting)

Aladrin (926209) | more than 7 years ago | (#18315151)

You should have left out the mess about the tv, etc. It isn't affected and has nothing to do with this. Mentioning it only clouds the issue.

The only difference is the livingroom, kitchen, and hall lights. So assuming you have 3 bulbs in the kitchen, 3 in the living room, and 1 in the hall, that's 7 bulbs that are on an extra hour a day.

It sounds like you're already at least a little energy-conscious, too, as most people will turn on a light if it's not quite bright enough in the room. You just leave them off, apparently. (I'm talking about the hall and kitchen, here.) So for most people, that only leaves the living room. And quite a few people watch the morning news before work, to get a handle on weather and traffic, especially. There's the living room lights on, too.

So for most people, as you encouraged me to think about, there is no difference. For the energy-conscious bunch, there's very little difference. And for me personally, there's no difference. DST or not, I get up before the sun has even thought about peeking its lazy ass over the horizon, and I'm home LONG before it decides to take a rest.

In the end, I think more energy savings come not from the DST itself, but from getting people to talk about saving energy.

Two last thoughts: Lightbulbs are getting more efficient every year. The saved energy from this scheme reduces every year. I wonder where the line is that we spend more energy talking and setting clocks than we save from the change?

Last thought: I used to hear this was 'for the children' so they wouldn't stand at the bus-stop in the dark. Why not just let them go to school an hour later, instead, if they're really worried about that? Most children already get home before their working parents, so it's not that.

Re:The other side (1)

bkr1_2k (237627) | more than 7 years ago | (#18315175)

Not to mention, a large portion of the work force simply doesn't get up early enough to need the lights any more now (or in a week or two at most) than they did last week. If most people go to work at 9am they don't get up until 7 at the earliest (usually) so they have about 15 minutes without light. Furthermore, as you stated, most people simply don't use as much energy in the morning as they do at the end of their work day.

Re:The other side (1)

teslar (706653) | more than 7 years ago | (#18315187)

Yeah, well, also from TFA:

Kellogg and Wolff came to their conclusion by studying Australia, where several states extended daylight-saving time (DST for short) by two months in 2000 to accommodate the Olympic Games in Sydney that year.
In fact, the two said, shifting Australians' clocks led to a tiny increase in power use.

So they're not exactly making it up and while you may think it's not logical, it does appear to be true. Whether the results apply to the US in the same way remains to be seen, of course.

Your TiVo Series 1 will work just fine as long as you're using the guide data to record everything.

When this bill was originally being talked about, various people said the study it was based on, done back in the 1970s was worthless. However they quickly got labeled as working for "big oil". Others mentioned that even using newer numbers the saving would not be great were also labeled as working for "big oil".
However all you "man is the prime source of global warming" can take heart, I have already seen a few articles where they are ignoring the claim that the change will save energy to focus on saying that it will save lives on the road, it is better for outdoor recreation, and it just makes people feel good because of the extra hour of sunlight at the end of the day.

It's a conspiracy! (0)

Anonymous Coward | more than 7 years ago | (#18315067)

The conspiracy theorist within me says that some portions of the IT industry wanted a mini-Y2K to make their services more critically required for a bit -- both so they could bill more for a bit and to remind everyone how necessary they are. In short, that some portions of the IT industry urged Congress to pass this stupid bit of legislation.

The same conspiracy theorist within me says that the stupid bits of Sarbannes Oxley legislating specific and no-value-add security policies were instigated by consulting firms in IT who knew they could churn out milliions in SOX pre-audits and SOX related services (by saying that everything needs changing in the pre-audits).

In the case of daylight savings time, I suppose that the old adage about not explaining with malice what could easier/better be explained by stupidity applies. I'm not so sure about SOX, though.

The letter from TiVo (2, Informative)

AtariDatacenter (31657) | more than 7 years ago | (#18315113)

Here is what TiVo sent me. The Thursday (Mar 8) before DST. Thanks for the warning!

Dear TiVo Subscriber,

As Daylight Saving Time commences three weeks early this year, we
thought we'd beat the clock to let you know how this unusual schedule might
affect recordings on your TiVo(r) Series1 DVR. (Hint: Chances are

While the TiVo service will continue to automatically record your
Season Pass(tm) programs and WishList(r) searches at the correct airtimes
without incident, there are two things to note:

1) For the three weeks that follow the new Daylight Saving Time start
date (March 11), your Series1 TiVo(r) DVR may display the incorrect

Again, to be clear, this is only a cosmetic issue and should not affect
your Season Pass(tm) and WishList(r) recordings.

2) If you have any MANUAL recordings scheduled between March 11 and
April 1, you
will need to adjust those recordings as appropriate. Here's how:

- From TiVo Central, select Pick Programs to Record, then To Do List.

- Locate your Manual Recording (by channel, date, time) and adjust
accordingly. For example, if you have a daily manual recording from 8:00 am

- 9:00 am, you will need to change it to 7:00 am - 8:00 am on March 11.
(Quick Tip: If there are no recordings in this list preceded by the
word "Manual", there's nothing further you need to do.)

- On April 1 be sure to change it back to its actual time, i.e., 8:00
am - 9:00 am.

For more details, please visit

Thanks for being a TiVo subscriber and here's to a beautiful spring!

benefits of DST shift (1, Interesting)

Anonymous Coward | more than 7 years ago | (#18315155)

1. Light outside when we leave work

2. And no, most of us posting here can't/won't get up at 6 AM - it's a guy thing

3. We don't have to listen to clueless politicians talking about moving DST as "low hanging fruit" in reducing energy consumption

4. We found a bunch of old code that was fragile and needed to be replaced

5. We all got a little drill on pumping out patches - "that which doesn't kill us" etc

6. Most of those clocks I have at home were drifting anyway. Now they have correct time.

7. Long weekend days in March.

8. DST article on Slashdot gives everyone something they can post about.

9. If Congress wasn't working on this, they'd be fiddling with the tax code. Which means Mr. Big and his corporation pays less, you and I pay more.

Die Time Zones (0)

Anonymous Coward | more than 7 years ago | (#18315165)

The whole idea of time being different around the world is stupid. The entire reason for DST is so "save energy"? What energy? So we now get up an hour earlier. Why can't we get up an hour earlier without an act of Congress? Are we so pathetic and weak that it takes a politician to motivate us? Seriously we are becoming subservient to others' ideas (by definition) when we cannot act of our own volition.

So here's what I propose. First, daylight savings time is stupid. Either turn it on or turn it off and don't change it back.

Second, to get to the heart of the problem, get rid of time zones. How often do we hassle with the dumb things? When flying on planes does it really take ten minutes to go from New York to CA and six hours to go back? No, it's all time zones. Should we need to figure in that difference?

When getting up in the morning why not just wake up when you're ready or when your daily requirements force you to get up? We have this insane notion that work hours can only be from 8 to 5 or 9 to 6 by the numbers. The fact of the matter is that you're going to go work (generalization alert) an eight-hour day no matter when that day starts (figuring in lunch, 9 hours). It so happens that I work from 1500-0000 GMT and that's fine with me. Why not tell everybody that? Customers call me from all over the world and I get to tell them, "I will be in the office from 8-5 MST which is 10-7 EST which is 3-12 GMT." Why do all that work? If the world unites on real time (GMT) we can take out these conversions. Half of the greatness of PHP's date() function may be eliminated (since it makes time conversions so nice) but the requirement for all of us to do these conversions will be eliminated. Business can post their hours based on whatever they want and those hours can be understood worldwide without going to to figure out what it really means. The world is moving to 24x7 anyway thanks to our beloved Internet so time zones mean less each day anyway.

Also, the sooner we (USA) get to metric the better. This whole other system is crap and I envy our metric-using overlords.

OTOH, I found TiVo's suggestions that I manually change everything on my Series 1 device to be somewhat...insulting.

Why on earth would you think that every piece of equipment must be DST / timezone aware? Time zone aware microwaves, time zone aware $3 radio clocks, time zone aware VCR, time zone aware wall clock? Yeah, sure... that would be a nightmare... For those used with DST it's no problem manually changing the date on each household equipment... And I suppose it will be more than a nightmare to explain to your 60yr old pops: "No, you shouldn't change the time on the fridge clock. You'll need to PATCH it. Yeah, is simple... just overwrite the PROM or whatever... ah and NO, you don't have to change time on the VCR too because it's DST aware... What? You left it on the default Japan time zone? No, you'll need to change that...". And so on

Wouldn't that create more and more issues? Is a $100,000 mechanical watch timezone/DST aware?

Well, in the case of a Tivo, you might have programmed it to record your favorite show at 7 pm.

Due to the DST change, unless your Tivo adjusts according, your show is no longer at 7 pm, so you don't get to watch your show.

Think a little.

ronys (166557) | more than 7 years ago | (#18315177)

Obviously, the closer you are to the equator, the smaller the difference between daylight hours in summer and winter.

However, for those North/South of about 30 degrees, the difference is significant. Not to mention the (measured, reference unavailable) reduction in traffic accidents due to fewer people driving home from work in the dark.

Anyone who had programed complex systems would tell you that it overcomplicates a lot of logic.

Just one example -- I used to work for energy trading company (think gas, power, oil, etc).

We had a datastructure for storing actual gas flow hour by hour. Guess what, it is an array with 24 entries, except for DST change days, when it can be 23 or 25. Thanks god we didn't operate in those backward off by hour and a half timezones.

Anyone who thinks the decision to keep the US on DST, or increase the time it is on DST, has anything at all to do with energy savings is woefully naive at best. The US increased DST because of commercial interests involved in outdoor entertainment and business. And those commercial interests bought congresscritters to do their bidding.

Any other government explanation is a lie. No exceptions.

sjbe (173966) | more than 7 years ago | (#18315257)

Noon is supposedly the time when the sun is at its highest point, meaning half the daylight is gone. Schedules vary but for most of us noon is not actually the middle of the day. Personally I wake around 7 most days and go to bed around 10-11. I don't dictate this, the companies I work with/for determine the hours of operation. For those keeping score that is ~5 hours before noon and ~10 after noon. (and no getting up earlier isn't really an option for me) It's just a lot nicer to have as many daylight hours as possible in the evening for exercise, errands, socializing, whatever... Cost savings are nice but I really am more interested in the quality of life. YMMV but I'm quite sure I'm not the only one judging by other comments. Daylight Saving Time just recognizes the reality that our schedules differ from the arbitrarily chosen noon time.

DST isn't about saving energy because it doesn't. It's about adding an hour of sunlight at the end of the day so that people can go out and shop - thus using more energy, not less.

There's a reason that American Chamber of Commerce has strongly support DST since it's inception.

I want my time back (0, Flamebait)

billcopc (196330) | more than 7 years ago | (#18315299)

DST is kind of dumb, yes, but what's even dumber is how twice a year around the clock shift date, a bunch of cocky little dorks write the same uncreative garbage about the evils of DST. Next year they might throw in a twist and say "DST causes homosexuality" or some southern retarded puke.

In the world, there are three driving forces: money, control, and religion. DST is driven by money. By having "more" sunny time, we have more spending time. Drive around, or drop by a terrace for a drink... things people are much less likely to do after darkness falls.

I personally wish we could leave our clocks alone and just have people get up one hour earlier if they need to. It's easier to have a billion people show up to work one hour early (with a few tardy folks), than to spend ages reprogramming every single electronic device on the planet to hopefully copy with this artificial rift in time. Linux does a semi-decent job by trying to keep everything in UTC, then cooking the timezone for display, but it's still a pain in the ass.

It's an ineffective, stupid move. (3, Insightful)

Peter Cooper (660482) | more than 7 years ago | (#18315321)

In a 24 hour society, daylight savings is an absolute farce outside of the May->August period when it's possible to have 16 hours of daylight. If there's, say, 14 hours of daylight, then you have 2 hours of darkness in most peoples' days wherever you shift the timezones, and that's only the optimum outcome because millions wake up before daylight and millions stay up after it.

If the government was really interested in "saving energy", it'd clamp down on emissions and fuel efficiency, and promote more effective techniques. Banning incandescent lighting and enforcing energy-saving bulb usage would strip several percent off of electricity demands year round and would cause a whole lot less annoyance than timezone changes. The EU and Australia have already figured this one out. []
