Set those clocks back 11/4

I don’t know how this always sneaks up on me, but Daylight Savings Time ends Sunday, November 4, 2012 at 2:00AM.    Don’t forget to set your clocks back, and change your smoke detector batteries, whether they need it or not.   Enjoy the early darkness in the evenings.

Standard time vs. Solar time?  If you want to read up on the theory of DST, and it’s history check this Wikipedia article.
