We need to have sequelize return dates in a particular format, not the default one. As far as I can tell, there is no way to set that up in options, or any other way. Short
you can define custom instance methods getDate/setDate which would translate date between sequelize internal representation and desired format like so http://sequelize.readthedocs.org/en/latest/docs/models-definition/index.html (see 'Expansion of models' section)
