title: ASP.NET Web API Date format in JSON does not serialise successfully
body: <p>All,</p>
  
  <p>We are using ASP.NET Web API where we have a REST based service with JSON for the payload. If I pass the following Date as a string e.g </p>
  
  <pre><code>sampleObj: {
  ...
  myDate: "31/12/2011 00:00:00",
  ...
  }
  </code></pre>
  
  <p>as an attribute value in the JSON payload, the date attribute gets deserialised into a DateTime.MinValue. Is the string format valid?</p>
  
  <p>We know the format "2012-10-17 07:45:00" serialises successfully but we cannot guarantee that all dates received will be in this format. What are the valid options? </p>
