title: Display time per timezone
body: <p>I am trying to display current time per timezone like the following, but it doesn't print out the time as expected.</p>
  
  <pre><code>long currentLong = System.currentTimeMillis();
  TimeZone.setDefault(TimeZone.getTimeZone("EST"));
  System.out.println("EST=="+ new java.util.Date(currentLong).toString());
  
  TimeZone.setDefault(TimeZone.getTimeZone("CST"));
  System.out.println("CST=="+ new java.util.Date(currentLong).toString());
  
  TimeZone.setDefault(TimeZone.getTimeZone("MST"));
  System.out.println("MST=="+ new java.util.Date(currentLong).toString());
  
  TimeZone.setDefault(TimeZone.getTimeZone("PST"));
  System.out.println("PST=="+ new java.util.Date(currentLong).toString());
  
  TimeZone.setDefault(TimeZone.getTimeZone("AST"));
  System.out.println("AKST=="+ new java.util.Date(currentLong).toString());
  
  TimeZone.setDefault(TimeZone.getTimeZone("HST"));
  System.out.println("HAST=="+ new java.util.Date(currentLong).toString());
  </code></pre>
  
  <p>When I execute the program I get this:</p>
  
  <pre><code>EST==Sat Nov 03 22:24:02 EST 2012
  CST==Sat Nov 03 22:24:02 CDT 2012
  MST==Sat Nov 03 20:24:02 MST 2012
  PST==Sat Nov 03 20:24:02 PDT 2012
  AKST==Sat Nov 03 19:24:02 AKDT 2012
  HAST==Sat Nov 03 17:24:02 HST 2012
  </code></pre>
  
  <p>I am wondering why the time for CST is same as EST and MST and PST are same.</p>
  
  <p>Can somebody tell me what the problem is?</p>
  
  <p>Thanks.</p>
