title: windows phone GameTimerEventArgs reset xna
body: <p>So I have a game running right now that uses the "e" in: private void OnUpdate(object sender, GameTimerEventArgs e) to keep the world speeds updated, however I don't know how to reset this GameTimerEventArgs for when I restart the game (without actually exiting the game)</p>
  
  <p>this is how I use it</p>
  
  <pre><code>  worldSpeed = (float)(3 + e.TotalTime.TotalMilliseconds / 10000);
  </code></pre>
  
  <p>suggestions?</p>
