Module | ActiveRecord::Timestamp
In: | lib/active_record/timestamp.rb

Active Record automatically timestamps create and update if the table has fields created_at/created_on or updated_at/updated_on.

Timestamping can be turned off by setting

      <tt>ActiveRecord::Base.record_timestamps = false</tt>

Keep in mind that, via inheritance, you can turn off timestamps on a per model basis by setting `record_timestamps` to false in the desired models.

      class Feed < ActiveRecord::Base
        self.record_timestamps = false
        # ...
      end

Timestamps are in the local timezone by default but can use UTC by setting

      <tt>ActiveRecord::Base.default_timezone = :utc</tt>
