However, dates are tricky. A customized format may be present in the backed. If you need to customized reopen the transform in your application.

DS.Transforms.reopen({
  date: {
    fromData: function(serialized) {
      // Transformations and return
    }, toData: function(deserialized) {
      // Transformations and return
    }
  }  
});
