title: Getting datetimes from cron format using javascript
body: <p>Does anyone know of any existing solutions using javascript that can parse a crontab and return all datetime instances between a given start and end date?</p>
  
  <p>ie if i have <code>0 * * * *</code>, start <code>24/10/2011 16:00</code> and end <code>24/10/2011 19:00</code> then it will return:</p>
  
  <pre><code>24/10/2011 16:00,
  24/10/2011 17:00,
  24/10/2011 18:00
  </code></pre>
