Active Record Timestamp
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>
Time Zone aware attributes
By default, ActiveRecord::Base keeps all the datetime columns time zone aware by executing following code.
ActiveRecord::Base.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 for certain attributes then you can do following:
Topic.skip_time_zone_conversion_for_attributes = [:written_on]
