title: Timer to display HH:MM:SS on a label
body: <p>Trying to display a run-time that will display HH:MM:SS so far i got the SS part working. But once it go to 60 it will jump back to 00.</p>
  
  <p>The code i got so far is:          </p>
  
  <pre><code>DateTime startTime;
  startTime = DateTime.Now;
  timer1.Tick += (s, ev) =&gt; { lb_runnerStatus.Text = String.Format("{0:00}", (DateTime.Now - startTime).Seconds); };
  startTime = DateTime.Now;
  timer1.Interval = 100;       // every 1/10 of a second
  timer1.Start();
  </code></pre>
  
  <p>Is it possible to get it to display 00:00:01 and when its at 1 minute 00:01:00 and so on.</p>
