            ActiveSupport::Deprecation.warn(              Time columns will become time zone aware in Rails 5.1. This              still causes `String`s to be parsed as if they were in `Time.zone`,              and `Time`s to be converted to `Time.zone`.              To keep the old behavior, you must add the following to your initializer:                  config.active_record.time_zone_aware_types = [:datetime]              To silence this deprecation warning, add the following:                  config.active_record.time_zone_aware_types = [:datetime, :time].strip_heredoc)
