   If there are any countries where the rules require an Olson-style
   specification other than "XXX>=(1 + n*7)", that's a strong argument in
   favor of just picking up the Olson code and using that

Lots of places have time zone rules for which Posix does not suffice,
but the Olson style specs do.  Australia, Britain, China, and Israel
come to mind, and I'm sure there are others.  People in those
countries who have only Posix implementations have the hassle of
changing their TZ strings every year.
