Hi Frank, The leap hour fix seems to be good enough; I could live with 29 minutes of discrepancy, and it might keep me politically involved trying to prod government to change it. I believe you're exaggerating with statistics comparing the suns' position at noon EDT to noon time in Philadelphia, PA. The proper comparison is noon EST, which goes to 75W, within a few miles of Philadelphia, PA. The comparison makes your position appear disingenuous.

And how do you feel about, let's say, Indianapolis being on Atlantic Time most of the year? Similarly, how do you feel about all of China being on one time zone? > > Which reminds me; there used to be "Decree Time" in the former USSR which was, if I understand correctly, year-round Daylight Saving Time. It's mentioned briefly in a Solzhenitsyn novel and the main character decries the "decree" as implying that the totalitarian regime thinks it can even control the Sun. Of course, it's no more than DST, but these sorts of associations have legs... > > -FER > > ---------------------------------------------------------------- > NavList message boards and member settings: www.fer3.com/NavList > Members may optionally receive posts by email. > To cancel email delivery, send a message to NoMail[at]fer3.com > ---------------------------------------------------------------- >
