Another tz compiler

[Paul Eggert]

Thanks for the heads-up.  I'll propose something like the following in
my next patch.

<li><a href="http://joda-time.sourceforge.net/">Joda Time - Java date
and time API</a> contains a class
<code>org.joda.time.tz.ZoneInfoCompiler</code> that compiles
<code>tz</code> source into a binary format that can be used by the
rest of the Joda API. Joda Time is freely available under a BSD-style
license.</li>


PS.  I wonder whether Joda Time can support Martian local time.  See:
