using Windows.Web.Http.Headers;

 public void DemonstrateHeaderResponseRetryAfter() {
 var response = new HttpResponseMessage();

 // Set the header with a strong type.
 HttpDateOrDeltaHeaderValue newvalue;
 bool parseOk = HttpDateOrDeltaHeaderValue.TryParse("", out newvalue);
 if (parseOk) {
 response.Headers.RetryAfter = newvalue;
 }

 // Get the strong type out
 System.Diagnostics.Debug.WriteLine("Date value in ticks: {0}", response.Headers.Date.Value.Ticks);
