title: Inconsistency when converting DateTime to JavaScript
body: <p>I have a ASP.NET webapi with a <code>DateTimeZoneHandling</code> set to <code>Local</code> and I am getting two different results when converting to a JavaScript date.</p>
  
  <p><strong>Example 1</strong></p>
  
  <p>Date returned from server <code>1932-10-13T00:00:00-04:00</code></p>
  
  <pre><code>var strDate = new Date("1932-10-13T00:00:00-04:00");
  
  strDate.toISOString();    // 1932-10-13T04:00:00.000Z
  strDate.toLocaleString(); // 10/12/1932, 11:00:00 PM
  </code></pre>
  
  <hr>
  
  <p><strong>Example 2</strong></p>
  
  <p>Date returned from server <code>2013-05-09T00:00:00-04:00</code></p>
  
  <pre><code>var strDate = new Date("2013-05-09T00:00:00-04:00");
  
  strDate.toISOString();    // 2013-05-09T04:00:00.000Z
  strDate.toLocaleString(); // 5/9/2013, 12:00:00 AM
  </code></pre>
  
  <p>I expected behaviour should always be midnight as the dates returned from the server are always midnight. It appears all recent dates parse correctly, however, dates far in the past are incorrect.</p>
