How to calculate time difference of 2 datetime object in AngularJS?
<p>I am very new in AngularJS and  I want to calculate time difference between <code>two datetime object with format</code>:</p>

<blockquote>
  <p>Hour:Minutes:Seconds</p>
</blockquote>

<p>But I want to get double digit output in time :</p>

<blockquote>
  <p>Expected Output: 00 : 00 : 04</p>
</blockquote>

<p><strong>Input:</strong> </p>

<pre><code>StartDate=2016-06-29 15:52:32.360

EndDate=2016-06-29 15:53:36.970

Expected output: 00 : 01 : 04
</code></pre>

<p>This is my code:</p>

<pre><code>public class User
{
      public int Id { get; set; }
      public Nullable&lt;System.DateTime&gt; StartDateTime { get; set; }
      public Nullable&lt;System.DateTime&gt; EndDateTime { get; set; }
}

Json output:

[
  {
    "Id": 121,
    "StartDateTime": "\/Date(1467195752360)\/",  //2016-06-29 15:52:32.360
    "EndDateTime": "\/Date(1467195756970)\/", //2016-06-29 15:53:36.970
  },
  {
    "Id": 122,
   "StartDateTime": "\/Date(1467195752360)\/",// 2016-06-29 15:52:32.360

    "EndDateTime": "\/Date(1467195758360)\/", //2016-06-29 15:53:36.970
  }
]
</code></pre>

<p>Code: </p>

<pre><code> &lt;td  ng-repeat="item in User"&gt;
      //How to display time difference here
      &lt;p&gt; Hour : Minutes : Seconds  &lt;/p
  &lt;/td&gt;
</code></pre>
