title: Carbon count minutes from timestamp
body: <p>I am working with the PHP Carbon library. And I am trying to get the total time in minutes from a timestamp.</p>
  
  <pre><code>$time = new Carbon('02:13:23');
  </code></pre>
  
  <p>And I was wondering if there is a function like countMinutes() or totalMinutes() that would return in this case <strong>133.38</strong> which is 2 hours + 13 min + 23 sec. = 133.38</p>
  
  <p>Or do I have to do it myself without the help of the library .. 120+13+(23/60)</p>
