title: html compatible Timer that doesn't pause on defocus?
body: <p>I have a libgdx project which I wish to deploy to both desktop and web.</p>
  
  <p>I used  <code>com.badlogic.gdx.utils.Timer</code> in the project, but found it paused if the app was defocused. So instead I switched to just  <code>java.util.Timer</code> which keeps ticking regardless.
  However, this gives compile errors under gwt.</p>
  
  <p>So I am looking for pointers on a Timer solution that works on both, yet also lets the app count "in the background".</p>
  
  <p>Ideas;</p>
  
  <ul>
  <li>do I extend/modify  <code>com.badlogic.gdx.utils.Timer</code> somehow?</li>
  <li>or use <code>java.util.Timer</code> in core, but somehow tell gwt compiles to use a different class?</li>
  <li>alternatives?</li>
  </ul>
  
  <p>Thanks,</p>
