Better yet, just have your program check whether the date is one of
the possible time change dates.  There are only 7 possible "spring
forward" dates and only 7 possible "fall back" dates:

Mar 8, Nov 1
Mar 14, Nov 7
Mar 13, Nov 6
Mar 12, Nov 5
Mar 11, Nov 4
Mar 10, Nov 3
Mar 9, Nov 2

You will only ever have to change these if the rules change (as they
did in 2007).
