title: Jenkins - Build Periodically doesn't work
body: <p>I have googled several posts, but can't find anyone mentioning their build periodically not inspite of configuring the cron in right way.</p>
  
  <p>I have the below setting for Build Periodically which I guess is correct, as I see the below comment. Still nothing happens. I have Jenkins 1.574 (latest stable build). </p>
  
  <p><i>"Would last have run at Friday, 8 August 2014 07:01:40 o'clock BST; would next run at Friday, 8 August 2014 07:16:40 o'clock BST."</i></p>
  
  <p><code># every fifteen minutes (perhaps at :07, :22, :37, :52)
  H/15 * * * *"
  </code></p>
  
  <p>I have tried with several combinations like 15 * * * * / H * * * * / etc. But nothing seems to help. Can someone help me debugging and pointing me at right direction?</p>
  
  <p>Thanks,
  Raghu</p>
