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

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

Timestamping can be turned off by setting

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

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

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