Re: US daylight savings for 2007

[Robert J. Chassell]

According to

on 2006 Mar 25

    In 1987 federal legislation fixed the period of daylight saving
    time in the United States as the first Sunday (previously the last
    Sunday) in April to the last Sunday in October; it was expanded in
    2005 (effective 2007) to extend from the second Sunday in March to
    the first Sunday in November. Arizona, Hawaii, and sections of
    Indiana do not use daylight saving time.

Thus, if you are in the US, in your .emacs file, put the following:

;; effective 2007, in the US, daylight saving time extends from
;; the second Sunday in March to the first Sunday in November.
;;   In 2007, daylight time begins on March 11 and ends on November 4. 
;;   In 2008, daylight time begins on March 9  and ends on November 2.

;; second Sunday in March
