Title
Body
I am converting some Rails controller code to be generic Ruby code. I came across this: expiration_date = 1.hours.from_now.utc.strftime('%Y-%m-%dT%H:%M:%S.000Z') ...and realized this is not standard Ruby. I get this error message: undefined method `hours' for 1:Fixnum (NoMethodError) How can I convert this to standard Ruby, or require/include the necessary libraries to make this work? Solution: Require the ActiveSupport Numeric class extensions : require 'rubygems' require 'active_support/core_ext/numeric/time'
