add or remove timestamps to or from a table

Sometimes developers forget to add the timestamps to a table when creating it.

Migration generator now generates a migration to add or remove timestamps to or from a table automatically via CLI

rails generate migration add_timestamps_to_users
  class AddTimestampsToUsers < ActiveRecord::Migration
    def change
       add_timestamps :users
    end
  end

rails generate migration remove_timestamps_from_users
  class RemoveTimestampsFromUsers < ActiveRecord::Migration
    def change
       remove_timestamps :users
    end
  end
