title: Does UTC observe daylight saving time?
body: <p>I am trying to write a script where i want to convert any timezone to <code>UTC</code> and reverse.
  But  from some where i came to know that while converting any timezone to <code>UTC</code>  with or without DST consideration it will give the same <code>UTC</code> time.
  For example:
  If i try to convert this one:</p>
  
  <pre><code>$mytime = '2011-03-31 05:06:00.000';
  $myzone = 'America/New_York';
  </code></pre>
  
  <p>to UTC with DST and without DST,i will get ..</p>
  
  <pre><code>(New_York-&gt;UTC DST=Yes)2011-03-31 09:06:00
  (New_York-&gt;UTC DST=No)2011-03-31 09:06:00 ..........
  </code></pre>
  
  <p>Is this corect ??If yes then why???
  Please anybody give me your answers.</p>
