title: Add one day into Joda-Time DateTime
body: <p>I have date <code>Wed May 08 00:00:00 GMT+06:30 2013</code>. I add one day into it by using <a href="https://www.joda.org/joda-time/" rel="noreferrer">Joda-Time</a> <a href="https://www.joda.org/joda-time/apidocs/org/joda/time/DateTime.html" rel="noreferrer">DateTime</a> like this.</p>
  
  <pre><code>DateTime dateTime = new DateTime(date);
  dateTime.plusDays(1);
  </code></pre>
  
  <p>When I print dateTime, I got this date <code>2013-05-08T00:00:00.000+06:30</code>. The joda date time didn't add one day. I haven't found any error.</p>
  
  <p>Thanks</p>
