Emner 2.4 + EmberFire findAll sorting descending

App: Ember 2.4 DB: FireBase;

Can't get data sorted with descending direction.

Using

export default Ember.Route.extend({
model: function() {
    return this.store.query('message', {
        orderBy : 'time'
    });
}

});

for getting list of my messages. But I need to get it in descending direction.

Have already read EmberFire doc and api doc http://ift.tt/1x2r85r http://ift.tt/1PoL0G4

didn't find any clear explanation in Ember 2.4 guide.

Thanks in advance
