title: Writing a cron Expression in springs
body: <p>I am using springs task scheduler(ConcurrentTaskScheduler) to schedule my tasks.
  I am using the API </p>
  
  <pre><code>public ScheduledFuture schedule(Runnable task,Trigger trigger)
  </code></pre>
  
  <p>to execute my tasks.The trigger I am using is the CronTrigger.<br>
  I am initializing the trigger using the following statement   </p>
  
  <pre><code>Trigger trigger = new CronTrigger(cronExp);
  </code></pre>
  
  <p>I need to write a cronExp in such a way that it starts at a specific date and executes daily from then on.</p>
  
  <p>I checked out the API for ConcurrentTaskScheduler but I could find appropriate API to achieve/I might have missed some API.</p>
  
  <p>Can anyone suggest me a way to achieve the above requirement?</p>
