ruby-on-rails - Rails 4 + Postgres = Missing milliseconds in model timestamps

Question

I have timestamps in my model created with t.timestamps command in the migration.

If I look in the database directly, the milliseconds are stored correctly. But when I fetch the object the milliseconds are not there.

Model.first.updated_at.iso8601(3)
 => "2013-09-28T13:43:58.000Z"

Why isn't the milliseconds fetched from the database?
