title: Dates not saving correctly in react-native realm
body: <p>I have an object with the following schema:</p>
  
  <pre><code>{
     name: "TestModel",
     properties: {
        "dateCreated": "date"
     }
  }
  </code></pre>
  
  <p>Whenever I save the model to the database with dateCreated: new Date(), the date itself appears to be saved incorrectly.</p>
  
  <p>I open the .realm file up in Realm Browser and it's listing a date in year 48212.  Does the react-native version of Realm store the dates in a different format than iOS and Java?  Is there a way I can force it to store the dates in the same format?</p>
  
  <p>Thanks</p>
