Krishna Dagli writes "Two Ph.D. students at the University of California at Berkeley say that Daylight Saving Shift will not do any good or create any energy savings. We are already spending money for software upgrades in the name of saving energy and after reading following article I wonder has congress really studied the impact of DST shift? " I also read some back story on the concept; OTOH, I found TiVo's suggestions that I manually change everything on my Series 1 device to be somewhat...insulting.
Unofficial estimates claim that costs due to the DST change well exceed a billion dollars TODAY which is more than the theoretical energy savings added up over 10 years. The cost is real and immediately incurred. The savings is nebulous and not guaranteed. Even 5 year old kid math can figure this one out. Imagine if we spent that billion dollars on alternative energy research, or energy conservation efforts - we would end up saving a LOT more money and energy than any fucking stupid DST change could have. The DST change cost my company alone well over $100K in direct costs and lost productivity. Considering what our company went through, I hate to think of what fortune 1000 companies spent - I would assume that it would be in the millions for a good number of them.
Energy savings or not, I like the extra hour of daylight in the evening. It's extra time to play ball, take the dog for a walk or just let my kid play outside.
I'd go for double daylight savings if I could.

On/. we obey the laws of thermodynamics. You are absolutely, 100% using more energy running your headlights in your car. ALL of the energy used by your car comes from the gasoline that you put into it (with the small exception of any charge already in the battery when it was installed). Therefore, you are using more gasoline with your headlights on than you would if they were off. It might be too small to easily measure, but the difference is there.
If you want some tangible proof of this, find a small hand cranked generator and hook it up to a blinking light bulb. You can actually feel the crank get harder to turn when the light is lit and become easier when it goes off. So the more electricity used by your car, the more gasoline you use or your battery goes dead.
I agree. I live near NYC and it does WONDERS for my morale. 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.

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.
My girlfriend's after a house with a south-facing yard, so as to catch all the sun it can (she's a garden enthusiast). It's amazing how many estate agents don't actually know which direction a given house faces.
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

"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."
When I camp I get up with the sun and set up camp around sunset regardless of what the clock says. DST doesn't give you more daylight.
Energy savings or not, I like the extra hour of daylight in the evening. It's extra time to play ball, take the dog for a walk or just let my kid play outside.
So why don't we all just keep the clocks an hour ahead, and get that "extra hour" all year round?
I want my daylight savings time for one reason - so I'm not woken at an ungodly (Ungodly? unGodly?) hour when the sun rises at its earliest, and I know I would be - if the sun didn't, my husband, who is very reactive to sunlight, would be awake and that would do it.
I live in Indiana, and I'm thrilled that we're finally doing DST.
According to the SANS Incident Handler's Diary [sans.org], various issues have been reported in Cisco VOIP phones, Blackberrys, Veritas aka Symantec BackupExec, and Watchguard firewalls.
According to CNN.com, 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?

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 slim.)
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 time.
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.

Thanks for being a TiVo subscriber and here's to a beautiful spring!
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.
Why don't we just set the clocks back 9 hours? Since Daylight Savings Time adds an hour of light, doing this will make it daytime all twenty-four hours. It's a win-win scenario!
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.
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.
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. [scotsman.com]
Psychologically, I feel a hell of a lot better when it's lighter out later. I know there are millions of people who have some sort of seasonal depression thing that are equally as delighted. I don't know if it saves any energy, but driving home from work when it's nice and bright out and being able to go for a nice walk or something in sunlight makes me happy.
If you live in the northern US and are doing the responsible thing and turning your central heating down overnight, then getting up an hour earlier means you're turning the heat back up earlier. Why is this wasteful? Because on sunny days in March there's significant solar gain once the sun's up. In my house that can be enough that the heat doesn't even need to be turned on in the morning - unless we get up too early.
In the evening, both the house and the outside environment lose their heat relatively slowly. The darkest hour isn't literally just before the dawn, but the coldest hour is. It's much better to spend the coldest hour under the covers - from an energy use point of view - than to get up during it or right on its tail and turn the furnace up to compensate.
Of course, if the government just looks at electrical use, this may not show in areas that don't primarily use electric heat. The increase in oil and natural gas use though, from this idiocy, will be real and significant.
A few years ago the Wall Street Journal estimated that every year we lose billions in productivity worldwide this week, due to simple grogginess. Hundreds of millions wake up an hour earlier than usual then spend a week trying to adjust. It sucks complete ass.
I have a toddler. Toddlers don't spring forward very well. Put them to bed an hour early and they'll spend two hours fighting it. Then get them up an hour early and see how happy they are to see you.
Please, please, either ditch it completely or use it all year long. I really like having an extra hour of daylight to spend outside with the boy, the dog, and the missus.
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.
Dude, I'm so glad you brought this story to light. I've been telling my friends this story for years, and they look at me like I'm crazy. Truth be told, they look at me like that no matter WHAT I'm talking about, but even more so when I get started on "The Indiana Thing." I drove, naively, into Indiana in 1983, searching for the woman in the L'eggs (panty hose) advertisement in my Mom's Redbook magazine. I was operating under the mistaken premise that Indiana was - rather than the breadbasket of America - the "Pantyhose and Nylons Capital of the World, due to an unfortunate misspelling of "hoosiers" in the budget encyclopedia set that my Mom purchased from someone at her office.
Driving around vainly searching for the L'eggs headquarters, the headlights in my '73 Chrysler Newport burned out halfway through my second day there, and I couldn't find my way back to the border. With a horde of cannibals closing in around my car (which only went about 10 miles between fillups - of gas, oil, or coolant) I thought the end was near. Quick thinking saved my life that day, and my penchant for popcorn. I ducked into the back seat and quickly fashioned a mask out of a box of Orville Redenbacher popcorn, and the cannibals began to bow and chant all around the Newport.
You didn't TELL your readers that Orville Redenbacher was a God to the denizens of once-dark Indiana, friend. Did you forget? Not likely. Were you, perhaps, brainwashed into secrecy? Possibly. Or, more sinister still, are you STILL a member of Redenbacher's scattered army of darkness? Just waiting for a new Governor to come in and repeal the DST proclamation?? State your motives, Sir!
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.
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.
Time zone specific calculations are on the client end, as all NTP sources give time in UST. So even if your embedded device is time syncing, if the software says "DST starts in april in timezone X" it is going to be wrong (even if it is very close to being wrong by an hour). The GP ignores the fact that no amount of "flexibility" in the DST implementation is going to make it economically feasible to support a $50 device for longer than production run. The thing to fix is setting up a public system that stores time offsets for all localities and make it a standard part of all OSes, like NTP.
Now if only they used it. I've got an analog radio clock that doesn't even display the date, but for some reason they decided to read the date bits and do some calendar calculations (or hard code the next X years of DST dates) to calculate DST rather than reading the flag.
I don't understand why you wouldn't use the flag -- it seems easier to just read the flag than to calculate the start/stop dates. There's even a countdown so you can miss several days of syncing before the switch and still know when it should happen. Apparently not all clock designers share my hatred for calendar calculations.
FYI: Common radio clocks use the 60kHz WWVB signal not the 2.5-20 MHz WWV signals. They both contain the digital timecode information, but WWV and WWVH also include frequency information (440 Hz, 500 Hz, 600 Hz, 1000 Hz and 1500 Hz beeps) and vocal timestamps, and reports about the weather, GPS health, and solar/radio conditions. In general WWV/WWVH are intended for manual use (all the time information is available in a format useful to human ears) and use outside the WWVB range, but WWVB is more accurate where available (better straight-line propagation) and less complicated to decode electronically due to the extremely low bit rate (a standard serial port can decode directly from an AM amp).
The thing to fix is, getting rid of the DST change completely
Or at the very least, the acronym DST should change. Since the so-called "standard" time lasts from the first Sunday of November to the second Sunday of March which is 19 weeks, and the "daylight saving time" lasts the remaining 34 weeks, the one which lasts longer (summer time) should be called "standard time", while the winter time, opposite of DST, should really be called "daylight wasting time".
Really, if we're so save daylight, why not save it all year long? Otherwise, we're just wasting it.
Not at all. The last change in the USA was 20 years ago.
In the US, it was changed federally in 1918, 1920, 1942, 1945, 1966, 1974, 1975, 1985, 1986 and 2007. That averages out to about once per decade. Up until 1966, many individual states also fiddled with the times. Even today, states are allowed to opt in and out of DST altogether, and Indiana just recently changed its rules.
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).
Yup, I heard the story on NPR. It was an interview with Michael Downing, author of the book "Spring Forward: The Annual Madness of Daylight Savings Time". He said there's not much energy savings, but more shopping because of DST.

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.

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. [scotsman.com]

The coldest hour (Score:4, Informative)
If you live in the northern US and are doing the responsible thing and turning your central heating down overnight, then getting up an hour earlier means you're turning the heat back up earlier. Why is this wasteful? Because on sunny days in March there's significant solar gain once the sun's up. In my house that can be enough that the heat doesn't even need to be turned on in the morning - unless we get up too early.
In the evening, both the house and the outside environment lose their heat relatively slowly. The darkest hour isn't literally just before the dawn, but the coldest hour is. It's much better to spend the coldest hour under the covers - from an energy use point of view - than to get up during it or right on its tail and turn the furnace up to compensate.
Of course, if the government just looks at electrical use, this may not show in areas that don't primarily use electric heat. The increase in oil and natural gas use though, from this idiocy, will be real and significant.
The cost of springing forward (Score:5, Interesting)
I have a toddler. Toddlers don't spring forward very well. Put them to bed an hour early and they'll spend two hours fighting it. Then get them up an hour early and see how happy they are to see you.
Please, please, either ditch it completely or use it all year long. I really like having an extra hour of daylight to spend outside with the boy, the dog, and the missus.

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.

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.

Fortunately, WWV includes a DST flag so that at least those so-called "atomic clocks" (actually radio clocks) automatically changed at the right time.

I don't understand why you wouldn't use the flag -- it seems easier to just read the flag than to calculate the start/stop dates. There's even a countdown so you can miss several days of syncing before the switch and still know when it should happen. Apparently not all clock designers share my hatred for calendar calculations.
FYI: Common radio clocks use the 60kHz WWVB signal not the 2.5-20 MHz WWV signals. They both contain the digital timecode information, but WWV and WWVH also include frequency information (440 Hz, 500 Hz, 600 Hz, 1000 Hz and 1500 Hz beeps) and vocal timestamps, and reports about the weather, GPS health, and solar/radio conditions. In general WWV/WWVH are intended for manual use (all the time information is available in a format useful to human ears) and use outside the WWVB range, but WWVB is more accurate where available (better straight-line propagation) and less complicated to decode electronically due to the extremely low bit rate (a standard serial port can decode directly from an AM amp).

Or at the very least, the acronym DST should change. Since the so-called "standard" time lasts from the first Sunday of November to the second Sunday of March which is 19 weeks, and the "daylight saving time" lasts the remaining 34 weeks, the one which lasts longer (summer time) should be called "standard time", while the winter time, opposite of DST, should really be called "daylight wasting time".
Really, if we're so save daylight, why not save it all year long? Otherwise, we're just wasting it.

Up until 1966, many individual states also fiddled with the times. Even today, states are allowed to opt in and out of DST altogether, and Indiana just recently changed its rules.
