title: Change format in Android Chronometr to show millisecond
body: <p>i'd like to change format in my android chronometr to show millisecond. So far I used this tip:</p>
  
  <pre><code>    mChronometer.setOnChronometerTickListener(new Chronometer.OnChronometerTickListener() {
          public void onChronometerTick(Chronometer cArg) {
              long t = SystemClock.elapsedRealtime() - cArg.getBase();
              cArg.setText(DateFormat.format("kk:mm:ss", t));
          }
      });
  </code></pre>
  
  <p>but i dont know the symbols for millisecond. Is there something? Thanks!</p>
