Thanks, I didn't know about these limitations. So it's a subset of what
RFC 7808 envisions.

Is the idea that a web server would wait for a request about some
particular range of time zone data, and then fire up an instance of zic
to generate just that data? That sounds slow.
Or were you thinking of making zic a long-running process, or caching
its results via something like Squid? Something like that might be
doable. It sounds reasonably ambitious....
