Alternatives to Daylight Saving Time? 755

Wellington Grey writes "Daylight saving time almost upon us. The arguments about its possible benefits and drawbacks come up twice every year. Does it save energy or lives? Possibly, but it does definitely cause a great deal of inconvenience. My question is this: what do you think would be the best possible system to replace DST with? What is the best way for humans to deal with the inconsistent amount of light over the year and still foster coordination over disparate time zones?"

    Do away with DST. If people want/need to get up earlier or later to take advantage of the daylight then JUST GET UP EARLIER OR LATER! There is no good reason to change the clock backward and forward. Lots of places don't do it and they don't have any problems. STOP DAYLIGHT SAVINGS TIME!

    I agree, do away with it, and the 9-5 business model dates back to the days of bartering. It was implemented before mankind had the ability to control light. First we need to make more environmentally sounds lighting sources. Then the answer to a lot of our current problems can be resolved by moving to a 24 hour society. It would create jobs, reduce traffic thus improving fuel efficiency and reducing accidents. It will allow people to work during hours which may increase productivity. Personally even though I live on the east coast, I still feel my body is stuck on PST. I've lived in this time zone for about 20 years now, but my ideal day would be 11 to 8.

    DST served a useful purpose at one time. It *does* reduce energy usage...for lighting. Back in the early part of the 20th century, the largest portion of home electrical usage was for lighting. Nowadays it's such a small part this savings has no measurable effect.

    The effect it does have is actually increasing energy usage as people crank on the AC when they get home earlier in the daylight of afternoon and it's hotter. And AC is vastly more expensive to operate than a bulb.

    As others have pointed out (http://irc.nrc-cnrc.gc.ca/pubs/fulltext/nrcc49212/nrcc49212.pdf), Daylight Savings Time likely doesn't save us any energy. This, of course, makes sense as if people are getting up earlier to avoid it being dark when they get home, they're still using electricity in the morning which is now dark. In short, the only way that daylight savings time in the modern day is beneficial to anyone is people who want to play sports or do something else outdoors after work. Not only that, but studies have shown that Daylight Savings Time often actually costs companies money due to needing to change clocks, employees who show up late/early to work during time changes and computer errors resulting from time changes. The solution, is to abolish Daylight Savings Time and save us all some time, money and bother.

    Daylight Savings Time has enormous costs and very little value in return.

    We should get read of it and say, "Good riddance..."

    If there are issues with available daylight in a particular area, then the times of events should be adjusted accordingly. If it is to dark at 7 AM for kids to go out in order to reach school at 8 AM, then push back the start time of school, etc., to 9 AM.

    In reality, this is what Daylight Savings Time does, but at much greater cost.

    The worldwide inter-connectedness of business is a strong argument AGAINST the 9-5 schedule. What good is standardizing on "9-5" when your customer on the west coast and your partners in India, Japan, and England all have their own, different 9-5?

    Who the hell even picked 9 and 5, and what makes those particular numbers so special that everyone has to change our entire time system twice a year to make sure those are always work hours?

    If every business adopted a very simple "go to work when you have to and leave when you have to" policy, we wouldn't care what the damn clock said, and would need neither time zones nor daylight saving time.

    So we have non-DST all year round and work from 8am to 4pm so that midday is always when the sun is at its zenith.

    Those at certain latitudes could also have summer hours of 7:30am to 4:30pm, and winter hours of 8:30am to 3:30pm, i.e. a shorter business day in the winter.

    Midday and daylight hours are going to vary throughout the year and across the planet anyway.

    "Pretend it's an hour later than it is,"

    Time measurement is an artificial construct. The time is when we say it is, there is no pretending it's a different hour.

    If you don't want to take the 10 seconds to adjust your clock, then fine but don't whine about doing the 'math' in your head. If adding or subtracting 1 in you head cause so much trouble, find some other place to post.

    Be that as it may, I'm one to prefer natural light over artificial light, and it is simply not an option to change my schedule. The way I see it, DST year-round is much better. It really comes down to personal preference, though, which makes it really hard for any democratic-ish countries to change it.

    Never mind that we live closer to the equator, it is bloody hot outside during the day and who on earth, apart from tourists, want to go out in that sun in the middle of the day. It burns!

    I'm an early riser. I get up hours before I have to go to work. That's when I clean and shit, so when I come home I can chillax. Many do the same. If you want daylight savings so you can see more daylight, adjust your own clock.

    Farmers are generally opposed to DST because we cannot begin work during harvest until the sun has dried out the crops sufficiently from the dew the previous night. Therefore, when DST is in effect, we can't start working in the fields until an hour later, and must end work when the sun goes down, which is now an hour later. This means we don't stop working until 9:00 instead of 8:00. Since we would all like to be able to get in an hour earlier, but still complete a full day of work, we are not big fans of when the clock artificially shifts to make us stay at work later.

    Moved here from Michigan 5 years ago. I don't miss DST at all. I just know that when I wake up at 5am, during the spring/summer, it's nearly broad daylight and in the colder months it's pitch black out. Right now, it's pitch black at 5am, at 5:30, I see some sunlight, by the time I get in my car at 6-615:am, it's daylight.

    Right now, I see the idiodicy of DST. You don't actually get more daylight, we just fool you into thinking you do.

    Exactly this. If it's too dark when you get up or when you want to open your business, don't change the clock, change the time you get up or open your business.

    If that's too hard, lets have DST year round. Standard time is only in effect for a couple months anyway. Keeping DST through the winter would keep it light when most people get off work, which is when it actually matters anyway. I know I'd rather get up in the dark, and have an hour of daylight after work to play with, rather than getting up at dawn and wasting that hour getting ready for work.

    I think they picked 9-5 As Sunrise as 8:00 is the latest time (without DST adjustment) the sun comes up the North Part of the United States. Allowing people of pre-alarm clock days to wake up when the sun rises. Enough time to prepare for work and get there an hour later. As for the 5 it is 8 hours later. Probably 8 hours as it can easily split up your day. 8 hours for sleeping, 8 hours for work, 8 hours of your own time... A healthy balance approach. As Well it can be split into 2 4 hour increments falling in the middle at noon for Lunch, and using the AM/PM to really help divide the day. As well 5:00 is when the sun sets on the shortest days of the year. So in general allowing lighted working conditions during your work day.

    Over here in Germany we use 24 hour time and UTC might not be a hard sell either (we're UTC +1/+2).

    It would definitely make things easier if at least international businesses and communities talked UTC. Remember the Firefox download day where people from half the planet wondered why Mozilla hasn't started the action even though the date/time specified on the site have already been reached. Only afterwards did many people learn that Mozilla meant that time in some American time zone nobody has ever heard about.

    If you try to give a date/time to someone who's probably not from your own country it's usually a bad idea to use local time. UTC was made for a reason and arguably should have greater significance on the internet.

    The idea of an 8-hour day (and the 40-hour week) has only been around since about the beginning of the 20th century. It's mainly originated from workers' demands in response to conditions in which many factory owners required people to work 12 or more hours a day. Later, it was reinforced by legislation requiring overtime for hours in excess of 40 in an attempt to reduce unemployment. Before industrialization, there was little concept of a "standard" workday. Farmers worked however many hours were necessary to maintain their crops and livestock, even if it meant working from sunrise to after sunset. Shopkeepers in town set their hours according to their needs.

    If DST weren't an issue, wouldn't it have been more natural to set an 8-hour workday to run from 8 AM to 4 PM rather than one hour later? In the northern tier of the contiguous U.S., it's common for the sun to set between 4 and 5 PM in the winter. And the sun is almost always up before 8, except for some places close to the Canadian border or near the western edge of a time zone. A workday ending at 5 instead of 4 would have made things somewhat more complicated in a society where electric lighting hadn't yet become ubiquitous. Does anyone know how the hours 9-5 got chosen rather than some other 8-hour span?

    Daylight Saving Time really only works (if it works at all) for a narrow range of latitudes.

    Too far south and the sun sets at the same time all year anyway. Too far north and the sun sets ridiculously late in the summer, and sets very early in the winter. Few of our southern hemisphere friends live far enough south for this to be an issue. Anybody here from Ushuaia?

    Even here, in southern Canada (49 degrees north), the sun sets at 1600 in the winter. If we didn't mess with time zones the sun would set at 2000 in the summer, and it isn't really dark until nearly 2200. How much later do you want it to set?

    Yep, WWVB, the main station used by radio clocks in the US broadcasts in UTC, all time zone and daylight savings adjustments are done by the clock which is why you have to set a time zone when you first buy one.

    This makes sense too because the radio station is used all over the country and neither it, nor your clocks have any way of knowing where you are.

    I never understood how DST saved anything anyhow. However, I do know that it causes a lot of intricate bugs, especially when programs contain time based loops. In most of the SDKs and Frameworks the default DateTime.Now returns the local time. A lot of software applications fail during DST switching because of loops in the code that compares two different times returns wild and unexpected results. I even had to mandate using DateTime.UtcNow in the code all the time.

    DST should be eliminated. We're in a global economy and out of sync 1/2 the year with most of the planet. DST does not "Save" a single minute nor does it add a single minute to the amount of daylight on any day of the year. For those worried about outside activities during the dark hours, they should adjust their own schedules. Kids should not walk to school in the dark. There are carpools and buses for many. while schools could easily adjust their starting hours. There is nothing more Socialist than forcing the entire American society to conform to the fears of some parents and the inflexibility of many school administrators.

    It's late and you didn't provide any sources, so I won't either. The commerce clause has been invoked to cover absurd federal drug/culture war activities by the current administration. It was used in an attempt to fight California's emissions standards.

    It certainly has been abused by every single administration/Congress since FDR.

    You seem to be implying that the modern Republican Party supports a more equitable distribution of power between the branches or between the levels of government.

    I said nothing at all to imply that, nor do I believe it. I was just lamenting the decision by FDR to apply political leverage against the theoretically non-political SCOTUS in order to disregard the Constitution, which made it possible for succeeding administrations -- including the current one -- to ignore the Constitution.

    Further, I would argue that judicial support of new deal legislation came with the five justices appointed by FDR during his second term.

    Eventually, yes. But he broke SCOTUS to his will even before then. Look up the Judiciary Reorganization of 1937, also known as the "Court-packing" bill. It was never passed, but its threat was sufficient to cow the justices.

    I feel that an amendment should have been required to implement many of the New Deal programs. I also feel that many of those programs were a step in the right direction.

    I disagree. New Deal-style social programs are fine, but they should be implemented at the state level. Such economic manipulation may (or may not) be necessary, but it's not an appropriate role for the federal government.

    We tend to think of the states as having insufficient fiscal resources for carrying out such programs, but that's only because the bulk of the tax revenues go to the federal government. Had we not made the mistake embodied in the 16th and 17th amendments, the states would have had the necessary resources. As a benefit, the states would undoubtedly have taken different approaches, which would have provided an ongoing set of parallel experiments to see which approaches work best.

    End Standard Time, or as I like to call it, "pretend it's some unknown amount of time later or earlier than it really is". Seriously, solar time for a long time was considered true time, and there was resistance to going to standard time. All our time conventions are for convenience and other such benefits anyhow -- if DST increases benefits, use it, otherwise don't. It's all arbitrary anyway.

To the systems programmer, users and applications serve only to provide a test load.
