Nov 2 is chosen on purpose because it's still Daylight Saving time in
2007.  11/21 is not DST.  it's not a windows problem as windows
reports the date/time correctly. And if I unset TZ,   date command of
cygwin also reports data/time correctly.   Only when I set TZ=PST8PDT,
  it reports incorrectly.
