title: cron expression for every > 60 minutes job
body: <p>Is there any way to design the cron expression as to run every 70 minutes or 210 minutes i.e. > 60 minutes. I tried to search for this, but was not able to find this.</p>
  
  <p>I finally went with a wrapper script that would do the required time checking which was called every 5 minutes(or the optimal recurring time).</p>
  
  <p>How to accomplish such task in cron expression ?</p>
