title: How can I configure ASP.NET web service to only send LocalDateTime property of DateTimeOffset object as JSON?
body: <p>I have a bunch of entity class (generated by Linq to SQL) with a few DateTimeOffset properties in it. </p>
  
  <p>When I send that over the wire as JSON from a .asmx web service, the JSON serializer generates the following JSON:</p>
  
  <pre><code>{"DateTime":"\/Date(1252142834307)\/",
   "UtcDateTime":"\/Date(1252142834307)\/",

  <p>I would very much like to save the bandwidth and JSON parsing time the client. I would also really like to avoid having to project every single DateTimeOffset manually before sending it off to the web service.</p>
  
  <p>I realize the JSON serializer do as it is suppose to, so my question is this: Is there a way to configure the JSON serializer so that it just sends the LocalDateTime property of the DateTimeOffset object?</p>
  
  <p>Thanks, Egil.</p>
