title: Oracle equaivalent of java System.currentTimeMillis()?
body: <p>I want to be able to store the current time in milliseconds in an Oracle number field. How do I do this via a query?</p>
  
  <pre><code>select systimestamp from dual; 
  </code></pre>
  
  <p>returns the actual timestamp. Is there anyway that I can convert this into milliseconds the same way Java's <code>System.currentTimeMillis()</code> does?</p>
