cache_attributes allows you to declare which converted attribute values should be cached. Usually caching only pays off for attributes with expensive conversion methods, like time related columns (e.g. created_at, updated_at).
Returns the attributes which are cached. By default time related columns with datatype :datetime, :timestamp, :time, :date are cached.
