we could leave the parsing to the lib developers using some code that
is not loaded by default. the result of the parsing is then encoded in
a more lisp-friendly way and added to the repository (e.g.
factory-functions in one big .lisp file, read'able sexps in a one
timezone per file format, etc)

of course this is all superfluous complexity if the parsing code is
small, fast and doesn't need any external dependencies.

btw, i was wrongly suggesting that the link in my previous mail is
pointing to some canonical timezone repository. the most canonical db
i can find now is this: http://www.twinsun.com/tz/tz-link.htm (note:
this page has an "Other time zone databases" section). probably the
tzdata files are also compiled from this.
