title: can a JSON feed be filtered to just show time from timestamp string?
body: <p>I am remotely retrieving an external JSON feed via JSONP. The JSON feed contains much data including start_time and end_time variables in an array that have the time data encoded in the "JavaScript built-in JSON object and ISO8601" like this:</p>
  
  <pre><code>2016-01-21T13:00:00+10:00
  </code></pre>
  
  <p>I want to put the data in a preformatted table (there is a good reason why) and I want to remove the date data and just leave the time on the value (i.e. 13:00).</p>
  
  <p>Is it possible to filter/parse the entire JSON data object and convert all these timestamp data strings to just show time before I start using the data (like a preformat run directly on the API feed)?</p>
  
  <p>Example snippet of the JSON data:</p>
