What module(s) do I need to include to get 5.seconds to work in Ruby?

Question

Because apparently require 'date' doesn't include the method hours or seconds etc:

undefined method `hours' for 5:Fixnum (NoMethodError)

Am I missing something? Is 5.seconds only something you can do in Rails? If so, what is the require statement I need to get this to work in a ruby script?

Answer 1

ActiveSupport::CoreExtensions::Numeric::Time maybe

Answer 2

The following works for me

irb
>> require 'active_support'
=> true
>> 5.hours
=> 18000 seconds

Depending on your environment and rails version you may need to require 'rubygems' this should be done before the require 'active_support' line.

You may also have to require 'activesupport' instead of active_support if you have an older version of rails.
