Is Daylight Saving Shift Really Worth It?

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.

    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.

    Time zone specific calculations are on the client end, as all NTP sources give time in UST.

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

    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.

    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.
