# 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>
