module Timestamp
Ruby on Rails 4.0.13
Since v2.2.3Active Record Timestamp
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:
config.active_record.record_timestamps = false
Timestamps are in UTC by default but you can use the local timezone by setting:
config.active_record.default_timezone = :local
Time Zone aware attributes
By default, ActiveRecord::Base keeps all the datetime columns time zone aware by executing following code.
config.active_record.time_zone_aware_attributes = true
This feature can easily be turned off by assigning value false .
If your attributes are time zone aware and you desire to skip time zone conversion to the current Time.zone when reading certain attributes then you can do following:
class Topic < ActiveRecord::Base self.skip_time_zone_conversion_for_attributes = [:written_on] end
