title: Issue with calender object ,showing 30min difference when added one day minutes to the current date?
body: <p>Basically am trying to add some x minutes to some y date,</p>
  
  <pre><code>    Calendar startDateCal = Calendar.getInstance();
      startDateCal.setTime(selectedDates.getStartDate());
      System.out.println("before adding"+startDateCal.getTime());
  
  
      startDateCal.set(Calendar.MINUTE, (int) adjustTimeValue);
      System.out.println("After addindg"+startDateCal.getTime());
  </code></pre>
  
  <p>Output was</p>
  
  <pre><code>   before addingSat Apr 08 10:31:29 IST 2017
     After addindgSun Apr 09 10:00:29 IST 2017
  </code></pre>
  
  <p>I got adjustTimeValue as 1440 minutes so the output should be below one right ? after adding 1440 minutes</p>
  
  <pre><code>  After addindgSun Apr 09 10:31:29 IST 2017
  </code></pre>
  
  <p>Where is the problem why am getting 30 min less output  after adding total one days minutes?</p>
  
  <p>sometimes getting 39min also, so basically these extra minutes are not getting showed up.</p>
