RE: Daylight Savings Time - 2

Right - DLS all winter to save energy. It didn't work.

To keep it in perspective, all of China is one time zone.... They aren't sharing safety and health data with us to see how that's working at the far ends.

Here, the scientific community (Sleep Research Society, American Academy of Sleep Medicine, and Society for Research of Biological Rhythms) has on the basis of research, lined up behind year-around standard time as safest for the US. Of course, as soon as that recommendation came out, an un-named senator from Florida introduced the "The Sunshine Protection Act," which would establish a permanent daylight saving time in the U.S. I'm sure that children walking to school in the dark in Minneapolis won't understand how the sunshine is protected.

Have to assume that the various states of the US (as well as everybody else) are free to set their school, work, retail and general business hours to suit themselves and their place on the globe, without having to advance or retard all the clocks?
