title: NewtonJson DateTime format serialization
body: <p>I'm using NewtonJson.NET in order to de/serialize my classes to json format.</p>
  
  <p>I don't know why, but it serializes DateTime values like this example:  <code>2015-07-23T10:39:31.0017599+02:00</code>.</p>
  
  <p>My server understands ISO8601 format: <code>yyyy-MM-dd'T'HH:mm:ss.SSSZ</code>.</p>
  
  <p>I'm figuring out the problem is on milliseconds <code>SSS</code> part.</p>
  
  <p>How could I change it?</p>
  
  <p>I'd need to set this configuration as a globally form, so, no in each field for example. I'd like NewtonJson always serialize DateTime values as ISO8601 format.</p>
  
  <p>Thanks for all.</p>
