More on Daylight Savings Time


old_clock_.jpgBack in November, on the 6th day of existence of this blog (aahh, it seems so long ago!), I wrote a post giving a brief history of Daylight Savings Time. There was a pop quiz at the end: “Do you know which Department controls time laws in the United States?” and I had every intention of answering, but, well, I forgot.

So for all of you who have been waiting four months for the answer, here it is! (Drumroll, please). It’s the Department of Transportation. From “Saving Time, Saving Energy”:

In 1918, the U.S. Congress made the U.S. rail zones official under federal law and gave the responsibility to make any changes to the Interstate Commerce Commission, the only federal transportation regulatory agency at the time. When Congress created the Department of Transportation in 1966, it transferred the responsibility for the time laws to the new department.

Speaking of Daylight Savings, you can find a world-wide overview of DST on this webexibits site. Interestingly, in the US, Canada, and Mexico most of the country observes DST but there is a portion of each country that doesn’t. Likewise, different portions of Antarctica have different rules: Rothera (a British base) does not use DST, but McMurdo and Amundsen-Scott South Pole Station (US bases) do.

    The reason Arizona doesn’t have DST is they tried once, and it wasn’t very popular. I know there was some upset about schoolkids going to the bus in complete-darkness conditions, but also there was the perception with the amount of sun we get we really didn’t need it.
