I vaguely recall that the Red Hat preferences setup uses it (along
with a little map), but I don't have a handy pointer to the source code.
If you find one can you please email me a pointer to it?  That would
be a nice thing to put into our web page.  Thanks.

Surely this is a property of your Unix rather than of tzconvert.cgi
itself.  However, I don't think the Olson code works well yet on hosts
with 64-bit time_t.  (I haven't used it there myself.)

ZoneInfo.java, perhaps?  See <http://www.bmsi.com/java/#TZ>.
