No sooner did I make noises about seeing the last timezone update of
2005 when another one comes out. This one, even ADO hopes will be the last of the year. Obtained from: Arthur Olson, ftp://elsie.nci.nih.gov/pub/tzdata2005r.tar.gz

+# To reflect all this, the Canada and Winn rules have been adjusted to
