title: Calling a function every 10 minutes
body: <p>I'm not an expert, just a beginner. So I kindly ask that you write some code for me.</p>
  
  <p>If I have two classes, <code>CLASS A</code> and <code>CLASS B</code>, and inside <code>CLASS B</code> there is a function called <code>funb()</code>. I want to call this function from <code>CLASS A</code> every ten minutes.</p>
  
  <p>You have already given me some ideas, however I didn't quite understand.</p>
  
  <p>Can you post some example code, please?</p>
