Yeah, so I've heard quite a few times in the past two days. About setting clocks back and forth for daylight saving time being a nightmare -- well, no. It is for those that aren't used to doing it, I'll grant you, but it does get easier to understand and do once it's become common.
An interesting sidelight is that the idea of setting clocks ahead was first put into play in WWI, as a war economy plan. Then it went away when the war ended, was resurrected for WWII, and in the '50s it became quite common - and now we're nationally (except Arizona and Hawaii) using it. But - for what? I've heard more than three times that studies have shown either a very small saving in energy consumption (the idea being that with the daylight extending later in the afternoon and evening - folks will take advantage and do more activities and won't have to turn on the lights so early) -- either a very small saving or none at all - and even an increase in energy consumed (because, according to that study, folks took advantage of the extra light hours by going for rides -- and therefore using more gasoline and offsetting any savings in electricity.
And then there was the time in the latter '60s when individual cities could choose whether to go daylight saving or not. When I arrived in Houghton, Michigan, for college in 1967 - a drive from campus to the next town (Hancock) would require changing my wathc about 5 times in three miles (campus on DST, Houghton on standard, Post office on DST, lift bridge schedule on standard, Hancock on DST. That was a nightmare!
