title: A cron job that will never execute
body: <p>Is there any way to create a cron expression for not running the job at all?</p>
  <p>I though of using this expression :</p>
  <blockquote>
  <p>0 0 0 1 1 ? 3099</p>
  </blockquote>
  <p>...which will practically do the job as it will run on year 3099, but is there a cleaner way to do it?</p>
