title: Cron Expression being called multiple times
body: <p>I'm trying to run a job every day at a specific time for testing purposes that should've been every day at 11:20:00 and for the real thing it should be every day at 23:59:59. For whatever reason the job just keeps getting triggered every 5 minutes and I'm not sure why. See the code here:</p>
  
  <pre><code> static triggers = {
      cron name: 'reportTrigger', cronExpression: "0 20 11 ? * * *"
  }
  
  def execute(){
      //execute code that isn't relevant here
  }
  </code></pre>
  
  <p>I'm on version 2.0.9 of the grails quartz plugin, I've tried newer versions but that causes non of the other jobs (that do actually have to run every 5 minutes) to no longer work. </p>
