title: Parse custom date format using JSON.Net
body: <p>I'm receiving a JSON date in the <a href="http://en.wikipedia.org/wiki/Unix_time" rel="nofollow">following format</a>:</p>
  
  <pre><code>"launch_date": 1250553600
  </code></pre>
  
  <p>How should I modify the following to include a custom DateTime parser that allows me to convert that number into a <code>DateTime</code> object?</p>
  
  <pre><code>JsonConvert.DeserializeObject&lt;NTask&gt;(json);
  
  public sealed class NTask
  {
      public DateTime launch_date { get; set; }
  }
  </code></pre>
  
  <p>Alternatively I could use <code>long</code> and then parse it in another field but I'd rather avoid doing that, and have <code>JsonConvert</code> automatically parse it to DateTime through some converter.</p>
