Daylight Savings Change Proposed

AveryRegier writes "CNN is reporting that Congress has added an amendment to the Energy Bill to extend daylight-savings time by two months. They expect to "save the equivalent of 10,000 barrels of oil a day." How long it would take for the associated energy savings to overcome the cost to make, test, and deploy the necessary code changes? How would the cost of this change compare with Y2K? Does most date routines' reliance on GMT make this just an issue of presenting the right time to the user?"

    Here's a PDF of the amendment, as agreed, from the house.gov page on the session yesterday. Realistically, if it'll make that big of an impact, why not make Daylight Savings Time a year-round proposal? If this amendment is passed by the House, we will have a period of a little over 3 months annually (Dec, Jan, Feb) in which DST is not in effect. That seems ridiculous. Not to mention that if DST becomes year-round, the change in software becomes a static offset to GMT as opposed to figuring out when the annual switch days are. Even Windows allows you to set a time zone that ignores DST, so a company in permanent CDT would only need set their time zone to EST and not worry about changing the clocks again.

      Most farmers like DST so they don't need to get up so early in order to get chores done.

      Dairy farmers need to milk the cows at the same time every day. Cows don't really care what the clock says the time is. Cows are very much creatures of habit, as herd creatures tend to be; they like routine, and they hate change. If you milk cows even an hour late, they will kick, bellow, and generally be a pain to deal with, and they won't give as much milk. Eventually, they'll get used to the new schedule, and then they'll fight just as hard if you try to change it back.

      Changing the cows' daily routine twice a year is not something a wise dairy farmer would try to do: it's just easier to get up an hour earlier or later, and ignore the "official" time, in favour of true consistancy. After all, what's the real difference between 5:30 and 4:30 am, anyway?

      And if farmers can do it, I don't know why other businessmen can't: how hard is it to schedule your employees to optimize for daylight? They already need to schedule to optimize for other business expenses; what's one more?

      It's not like daylight savings time saves daylight: it just adjusts the clock, to pretend daylight is during "working hours", which we're of course free to change anyway. Why not just set $WORKING_HOURS to what we really want, and stop tampering with the clocks?
