title: How to format datetime in utc to local time format?
body: <p>I have a datetime object whose value is in format (got thru breakpoint)</p>
  
  <pre><code>dateTime = 2015-09-04T08:37:00.440-07:00
  </code></pre>
  
  <p>I am trying get corresponding local time.</p>
  
  <p>I used format <code>"EEEE, MMM d 'at' hh:mm a"</code>.</p>
  
  <pre><code>dateTime.toString(format);
  </code></pre>
  
  <p>But it does not take -07:00 hours offset into account and gives back:</p>
  
  <pre><code>Friday, Sep 4 at 08:37 AM
  </code></pre>
  
  <p>Expected Value:     <code>Friday, Sep 4 at 01:37 AM</code></p>
  
  <p>What am I missing?</p>
