70 Countries Set Their Clocks Back an Hour Tonight. But Why? (upi.com) 252

Posted by EditorDavid from the falling-and-falling-backwards dept.
Tonight 70 countries around the world set their clocks back an hour — including most of the United States, Canada, the EU and the UK.

Yet "The practice has drawn complaints about its disruptive effects on sleep and schedules," reports UPI, adding that "The American Academy of Medicine has called for an end to Daylight Saving Time, citing growing research that shows its deleterious effects on health and safety." [U.S.] Lawmakers are also increasingly wondering whether Daylight Saving Time is a good idea. At least 350 bills and resolutions have been introduced in every state taking aim at Daylight Saving Time since 2015, according to the National Conference of State Legislatures. Over the last four years, 19 states have passed similar legislation providing year-round daylight saving time if Congress allowed such changes.

Members of Congress have introduced legislation making changes to Daylight Saving Time, to no avail.

U.S. Sen. Sheldon Whitehouse, (Democrat — Rhode Island), said in a video posted to Twitter on Friday that the upcoming switchover was one of his least favorite times of the year since it means darker afternoons. He touted his Sunshine Protection Act that would make Daylight Saving Time permanent.

"We can do a lot better for daylight for everyone who is up in the afternoon," he said.
Also supporting that change is Florida Republican Senator Marco Rubio. "We're about to once again do this annual craziness of changing the clock, falling back, springing forward," Newsweek quotes him as saying. "Let's go to permanent daylight saving time. The overwhelming majority of members of Congress approve and support it. Let's get it done. Let's get it passed so that we never have to do this stupid change again."

But currently in America it's the Department of Transportation which is in charge of the practice, reports USA Today, and the Department believes that the practice saves energy, prevents traffic accidents and curbs crime.

So, as the Washington Post reports, "It's that time of the year again. We change the clocks back and we whine about it."

      I believe a lot of the controversy depends on where you live.

      The closer you live to the equator, the less sense DST makes. dark and light don't change that much.

      As you go higher in latitude, it helps to dampen the swings in daylight/dark, until at the highest, the daylight dark swings are too wild to make any compensation for. not much you can do about midnight sun or the days of darkness.

      Here in PA, in December and January, I'd get up and drive to work in the dark, leave work in darkness, and work in a windowless office. Weekends were weird with all that light outside.

        But DST is just making the situation worse. Yesterday it got dark 5:45pm here. Today it will now suddenly get dark at 4:45pm. That's a big sudden decrease that only accelerated the shortening of the day since the 8:45pm darkness summers. Afternoon is the time that matters. Not mornings. We shouldn't be trying to adjust daylight for super early when all everyone is doing is either sleeping or getting ready and traveling to work/school. Afternoon, when people are actually doing things, is when we should worry about daylight. And knocking out a whole hour of afternoon daylight after we've already lost a bunch is pants on head retarded.

    Tonight 70 countries around the world set their clocks back an hour — including most of the United States, Canada, the EU and the UK.

    Let me check Wikipedia: "In all locations in Europe where summer time is observed (the EU, EFTA and associated countries), European Summer Time begins at 01:00 UTC/WET (02:00 CET, 03:00 EET) on the last Sunday in March and ends at 01:00 UTC (02:00 WEST, 03:00 CEST, 04:00 EEST) on the last Sunday in October each year; i.e. the change is made at the same absolute time across all time zones."

        The natural sleep cycles are about 40 mins shorter in the Summer than they are in the Winter (yes, YMMV yada yada). A clock that runs the same during summertime as in the Winter is also unnatural.

        When I grew up, we didn't have Daylight saving time. In Germany, it was first introduced during World War I, then abandoned after the war again, reintroduced in 1940 during World War II., but abandoned again in 1950. And then it was reintroduced in 1980, and has existed ever since.

        My bet is: As soon as we abandon Daylight saving time, we will regret it, and after a few years, there will be a majority of people wanting DST back. A regular clock during the whole year is unnatural in general, as our bodies adapt to the changing day-night-cycle, and there will always be attempts to somehow fix the discrepancy between what the clock says and how we feel, by changing time between Summer and Winter.

        • In Germany, it was first introduced during World War I, then abandoned after the war again, reintroduced in 1940 during World War II.

          The Germans did not just introduce it in their own country, they also enforced it in the countries they invaded.

          They also annexed the occupied countries to the German time zone until this day, e.g. in Belgium (which is closer to the Greenwich Meridian, and was on GMT before the German invasions) they changed the time by 2 hours.

    • Shifting time by an hour does the opposite of what you think in regards to children going to school or coming home from school in the dark.

    Here's the thing. The variation in hours of daylight is proportional to some trigonometric function of distance from the equator. This means that the farther north you are (in northern hemisphere), the more you are going to like adjusting the clocks to deal with changes in when daylight occurs.
