title: Running a method every 15 minutes, every day, between certain times
body: <p>I want to run a method every 15 minutes, every day, between 08:01:00 and 16:31:00 London time.</p>
  
  <p>So something like this:</p>
  
  <pre><code>foo(); //run every 15 mins, everyday, between 08:01:00 and 16:31:00.
  
  public void foo(){
  //do stuff
  } 
  </code></pre>
  
  <p>I have tried using Calendar and Timer but I cannot get this to work.</p>
  
  <p>Thanks for our help.</p>
