title: Nifi processor cron based scheduling
body: <p>Below is the syntax I have tried with 0 30 0 * * ? or 0 30 1 * * ?, which should run at 12:30 or 1:30 midnight respectively.</p>
  
  <p>Also I have tired running the flow with cron in nifi for every 20 minutes duration, it worked perfectly.</p>
  
  <p>But we want it to be run, daily once at particular time as mentioned above example (0 30 0 * * ? or 0 30 1 * * ?).</p>
  
  <p>But it is not working. can anyone please guide.</p>
  
  <p>Thanks.</p>
