title: defaultValue of showTime attribute in antd datePicker couldn't set the time
body: <p>I'm using ant design for my react hook based development.  I am retrieving date from database over a network call and the date retrieved from database is look like &quot;2020-09-01T05:02:00.000+0000&quot;. It is a string. I have to parse this date and show the date value and time value through antd datePicker in my page. Though I've success with setting up date part but I'm stuck with setting up the time. Here is my code,</p>
  <p>###########
  Here is my datepicker
  ###########</p>
  <pre><code>                          &lt;DatePicker
                              name=&quot;Campaign-date&quot;
                              defaultValue={moment(formData['Campaign-date'].split('T')[0])}
                     
                              showTime={{
                                  defaultValue: moment(formData['Campaign-date'].split('T')[1],'HH:mm'),
                                  format: 'HH:mm'
                                  
                              }}
                              format={'YYYY-MM-DD HH:mm'}
                              style={{ width: '100%' }}
                              onChange={handleDateChange}
                          /&gt;
  </code></pre>
  <p>##########################
  Here is my handleDateChange function
  ##########################</p>
  <pre><code>const handleDateChange = date =&gt; {
      setFormdata({
          ...formData,
          'Campaign-date': date
              .format('YYYY-MM-DD HH:mm')
              .split(' ')
              .join('T')
      });
  };
  </code></pre>
  <p><strong>formData['Campaign-date']</strong> is the date retrieved from the database. I feel the <strong>showTime</strong> attribute is not working as expected. I want to get a result of &quot;05:02&quot; but instead the value shown is, &quot;00:00&quot;.</p>
  <p>I have tried different variation in showTime such as,</p>
  <pre><code>defaultValue: moment('05:02','HH:mm'),
  //or
  defaultValue: moment(formData['Campaign-date'],'HH:mm')
  //or
  defaultValue: moment(formData['Campaign-date'].split('T')[1].split('.),'HH:mm')
  </code></pre>
  <p>but nothing is working. It is always setting the value as &quot;00:00&quot;.
  And I have no problem with my onChange functionality. It is working perfect. The date/time change code wise working as expected. It is just the view on my page is not showing correct time.</p>
  <p>I'm really stuck with. Any help therefore, is much appreciated.</p>
