title: FreeMarker - Remove comma from milliseconds
body: <p>Using FreeMarker, I want to display a date into milliseconds:</p>
  
  <pre><code>${mydate?long}
  </code></pre>
  
  <p>but I get as output a comma separated millisecond:</p>
  
  <pre><code>524,354,400,000
  </code></pre>
  
  <p>is there any built-in function in Freemarker to remove comma ?</p>
  
  <p>Thanks</p>
