The word "overengineering" comes to mind...
We should simply list the available timezones in the documentation
(there is already an appropriate appendix, IIRC). Generating the table
will require about thiry seconds with "ls", so it hasn't seemed like an
urgent priority to me, but certainly it must be done before release.
