title: ZonedDateTime would use same timezone of winter when summer daylight saving?
body: <pre><code>ZonedDateTime zdt = ZonedDateTime.of(2015, 10, 18, 0, 30, 0, 0,
      ZoneId.of("America/Sao_Paulo")); 
  System.out.println(zdt); // 2015-10-18T01:30-02:00[America/Sao_Paulo]
  </code></pre>
  
  <p>You can see the hour is <code>1</code> while we set the hour as <code>0</code>, and timezone is <code>UTC-02:00</code> while daylight saving timezone should be <code>UTC-03:00</code>.</p>
  
  <p>But here is a different example:</p>
  
  <pre><code>ZonedDateTime zdt = ZonedDateTime.of(2015, 10, 18, 0, 30, 0, 0,
      ZoneId.of("America/Los_Angeles"));
  System.out.println(zdt); //2015-10-18T00:30-07:00[America/Los_Angeles]
  </code></pre>
  
  <p>You can see the daylight saving timezone is <code>UTC-07:00</code> and the hour is <code>0</code> as we set.</p>
  
  <p>Why are they different?</p>
