title: How to add minutes to time
body: <p>Guys I want to add Minutes to time for exemple I have 8:50h and I want to add to it another 8:50h;
  I have tried</p>
  <pre><code>time = time.Add(TimeSpan.FromHours(8.5)); // time variable already has 8:50:00 and time it's TimeSpan variable
  </code></pre>
  <p>but I got 17:00h (it treats it like floats) but I want it to be 17:40 (so every 60mins it will add an hall hour).</p>
