title: How to convert a Date between Jackson and Gson?
body: <p>In our Spring-configured REST-server we use Jackson to convert an object into Json. This object contains several java.util.Date objects. </p>
  
  <p>When we attempt to deserialize it on an Android device using Gson's fromJson method we get a "java.text.ParseException: Unparseable date". We have tried serializing the date to a timestamp corresponding to milliseconds since 1970, but get the same exception.</p>
  
  <p>Can Gson be configured to parse a timestamp-formatted date such as 1291158000000 into a java.util.Date object?</p>
