title: Use of "applicationSignificantTimeChange"
body: <p>May be I am asking a stupid question here. </p>
  
  <p>I recently noticed an UIApplication delegate method </p>
  
  <pre><code>- (void)applicationSignificantTimeChange:(UIApplication *)application {
  
  }
  </code></pre>
  
  <p>I was wondering what will be its actual use? Do we need to handle this. Can anyone explain a scenario that can happen in an iOS application and we need to do some coding here. </p>
  
  <p>My App is really sensitive to system time, that is the reason I am asking this question. After seeing this API , I have a feeling that I am missing something here to handle. </p>
  
  <p>I am just curious to know... :)</p>
  
  <p>Thanks,
