This Sunday Americans will participate in the annual ritual of setting their clocks one hour back to "Standard Time." Why? About.com Geography Guide Matt Rosenberg explains the origin and purpose of Daylight Saving (not "Savings") Time:
Daylight Saving Time was instituted in the United States during World War I in order to save energy for war production by taking advantage of the later hours of daylight between April and October.

I would love to see the heart attack stats on the morning of ‘Spring Ahead’, or for that matter a single corporate electric bill showing a positive result from this business…you come to work, you turn on the lights. Maybe not in 1914…maybe. What it seems to me, from my insane and paranoid viewpoint, is that this clock-changing exercise serves a dual purpose: one, to psychologically ensure that subject peoples understand the true power of their rulers (over Time itself! eat your hat, Canute!) – and to politically/socially disorient people. I once heard the excuse that it would increase golf course profits, and once that it would make children safer, I forget how. Whatever way you slice it, it’s f*&*%ng stupid. And a good Standard Earth Day to everyone!
