I want to use the Date::ABBR_MONTHS constant in my rails application. I see the Ruby stdlib documentation at http://www.ruby-doc.org/stdlib/ which does not seem to have this constant. However, this constant is there at http://stdlib.rubyonrails.org/
What is the difference between these two libraries?
This constant is working on my unix deployment machine but not on my dev machine on windows. Can anybody explain whats going on?
