title: Convert UNIX timestamp difference to minutes
body: <p>I have 2 dates, that I convert to UNIX timestamp - start date and confirm date. I subtract one from another and get numbers like these:</p>
  
  <p><code>-12643,
  0,
  3037,
  1509,
  -3069</code></p>
  
  <p>Basically, what I need to do is to get the difference between the two dates in minutes, but I don't know how to <strong>convert those to minutes</strong>. The end output should be something like: <code>-25, 13, 155</code></p>
