The correct way to go about with active_support/action_pack/rails it is: require 'rubygems' require 'active_support' time = Time.now.months_since(1) or time = Time.now.months.ago(-1) Note that active_support is the library that you're after, not actionpack (which is the library that provides the controller/view behaviour of rails) - it just happened to work in the previous example because actionpack requires active_support.
