The Standard Time Act of 1918 was a contentious idea even when first enacted. Repealed in 1919, it was brought back to life during WWII from 1942-45.
In 1965, the Uniform Time Act "standardized" the beginning and ending dates; even though the dates sort of meandered a bit until the Energy Policy Act of 2005 set our current "Spring forward-Fall back" dates.
We have moved from a largely agrarian society to today's mostly urban society where our days are simply part of the 24-hour day, 365-day year of everyday life. No longer does the Sun dictate when we start or end the workday.
I am sure that nothing will become of this, my annual rant against Daylight Savings Time but The Act no longer has the impact that it did more than a century ago.
PS: Don't forget to set your clocks forward (or is it back) today, Sunday 10 March 2013. Either direction, have a good one.
