title: JAXB dateTime format after XML generation
body: <p>I have short question:</p>
  
  <p>After xjc class generation from xsd, my object require Calendar and thats what I supply. But after marshalling it to XML my date format is as follows:</p>
  
  <pre><code>&lt;InfoDateTime v="2013-09-03T00:00:00+02:00"/&gt;
  </code></pre>
  
  <p>whereas I would like to have:</p>
  
  <pre><code>&lt;InfoDateTime v="2013-09-03T00:00:00Z"/&gt;
  </code></pre>
  
  <p>I do not use annotated jaxb but with binding file but is it possible without creating classes which can parse date and string?</p>
  
  <p>Thanks!</p>
