title: Is there a standard implementation for a GSON Joda Time serialiser?
body: <p>I'm using GSON to serialise some object graphs to JSON.  These objects graphs use <a href="http://www.joda.org/joda-time/" rel="noreferrer">Joda Time</a> entities (<code>DateTime</code>, <code>LocalTime</code> etc).</p>
  
  <p>The top Google hit for "gson joda" is this page:</p>
  
  <ul>
  <li><a href="https://sites.google.com/site/gson/gson-type-adapters-for-common-classes" rel="noreferrer">https://sites.google.com/site/gson/gson-type-adapters-for-common-classes</a></li>
  </ul>
  
  <p>It provides source for a type adapter for <code>org.joda.time.DateTime</code>.  This link is also what is referenced in the <a href="https://sites.google.com/site/gson/gson-user-guide" rel="noreferrer">GSON User Guide</a>.</p>
  
  <p>I expected to find a pre-rolled library that included joda-time serialisers that I could reference as a Maven dependency - but I can't find one.  </p>
  
  <p>Is there one?  Or am I forced to replicate that snippet in my own project?</p>
