title: adding date to Java util logger fileHandler name
body: <p>Hi I currently have this in my .properties file:</p>
  
  <p><code>java.util.logging.FileHandler.pattern = %h/programName%u%g.log</code></p>
  
  <p>I would also like to append a timestamp / username to this so its easy to identify log files does anyone know how?</p>
