title: How can I format a date within BIRT's Expression Builder
body: <p>I have a BIRT report that includes a data cell and one dataSetRow is a date (expirydate) in YYYY-MM-DD format.  I need it to be in DD-MM-YY format, can I do this within BIRT's expression builder?</p>
  
  <pre><code>... + dataSetRow["expirydate"] + ")"
  </code></pre>
  
  <p>I can't just format the whole cell, as it contains a variety of information.</p>
  
  <p>I'm using BIRT Report Designer, Version: 2.3.0</p>
