Thanks for the heads-up. I'll propose something like the following xhtml in my next proposed tz update. Comments welcome. (I must confess that at Twin Sun we've avoided DateTime in our Perl code for performance reasons -- I didn't know it had tz support these days.) <li><a href="http://search.cpan.org/dist/DateTime-TimeZone/">DateTime::TimeZone</a> contains a script <code>parse_olson</code> that compiles <code>tz</code> source into <a href="http://www.perl.org/">Perl</a> modules. It is part of the Perl <a href="http://datetime.perl.org/">DateTime Project</a>, which is freely available under both the GPL and the Perl <a href="http://www.perl.com/language/misc/Artistic.html">Artistic License</a>. DateTime::TimeZone also contains a script <code>tests_from_zdump</code> that generates test cases for each clock transition in the <code>tz</code> database.</li>
