title: format a date in a knockout foreach statement
body: <p>I am having an issue formatting a date field from a knockout model:</p>
  
  <pre><code>&lt;table class="signatures"&gt;
      &lt;tbody data-bind="foreach: $root.signatures()"&gt;
          &lt;tr&gt;
              &lt;td&gt;&lt;span data-bind="text: DateSigned"&gt;&lt;/span&gt;&lt;/td&gt;
          &lt;/tr&gt;
      &lt;/tbody&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>This is the result that I get:</p>
  
  <pre><code>/Date(-62135571600000)/ 
  </code></pre>
