title: Android Time class: is it locally linear with milliseconds?
body: <p>By this I mean:</p>
  
  <pre><code>Time time = new Time();
  time.setToNow();
  long millis = time.toMillis(false);
  time.monthDay++;
  </code></pre>
  
  <p>is </p>
  
  <pre><code>time.toMillis(false) == millis + 24l*3600*1000
  </code></pre>
  
  <p>always true?</p>
  
  <p>the same question with</p>
  
  <pre><code>time.hour++;
  </code></pre>
  
  <p>for I think the time system is extremely complex, I do not know what is guaranteed.</p>
