Dave,

You can currently opt out of time zone aware attributes for specific
attributes like so:

class Flight < ActiveRecord::Base
  ...
  self.skip_time_zone_conversion_for_attributes =
[:departure_time, :arrival_time]
  ...
end

With this setup, no time zone conversions will be done for
Flight#departure_time and #arrival time.

Does this give you what you need?
