title: How can I use the rails helper "distance_of_time_in_words" in plain old ruby (non-rails)
body: <p>Rails has an helper which converts distance of time in words using distance_of_time_in_words</p>
  
  <p>What do I need to include if I am just using ruby at the irb prompt to get this function?</p>
  
  <p>I tried <code>require 'action_view'</code> but it didn't help.</p>
  
  <p>I also tried <code>require 'active_support/core_ext'</code> but that didn't help either.</p>
