title: Get time of day from local datetime string
body: <p>I have a string that looks like this:</p>
  
  <pre><code>String localTimeString = "2018-03-01T17:20:00.000+01:00";
  </code></pre>
  
  <p>What's the right approach to get only the time of day in this string, in format "HH:mm"? </p>
  
  <p>(Min sdk is set to 19)</p>
  
  <p>All help appreciated!</p>
