title: What module(s) do I need to include to get 5.seconds to work in Ruby?
body: <p>Because apparently <code>require 'date'</code> doesn't include the method hours or seconds etc:</p>
  
  <pre><code>undefined method `hours' for 5:Fixnum (NoMethodError)
  </code></pre>
  
  <p>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?</p>
