title: Does rails have an API to check and see if times or dates exist?
body: <p>Supposing a guy doesn't want users to include months or days or anything that remotely sounds like a time in his text area form. Could he use something besides regex to validate that? Is there a built-in API for that? I do use the Chronic gem somewhere else, but if I used it for this purpose, it would probably be out-of-the-box.</p>
  
  <p>Here's an example .</p>
  
  <pre><code>I'm offering this wonderful sheep and it's only good until June.
  </code></pre>
  
  <p>Blam! Can't have this then because they said the word, 'June'. Can Ruby detect that?</p>
