title: Start Time and End Time in JMeter Scheduler
body: <p>I am working on JMeter version 2.5.1 and I want to set up a Scheduler for my Thread Group.</p>
  
  <p>I set the following values for scheduler fields:</p>
  
  <pre><code>Start Time = 2011/12/13 11:30:00
  End Time = 2011/12/13 11:32:00
  Duration (seconds) = 3
  Startup delay (seconds) = 5
  </code></pre>
  
  <p>My threads start after the delay of 5 seconds and keep running up to 3 seconds duration. But I cannot see any effect of Start Time and End Time on my threads.</p>
  
  <p>Kindly tell me what do these fields do in the process of running of threads.</p>
