title: Different NSTimeZone names being returned
body: <p>I've noticed that on some devices the <code>NSTimeZone</code>'s <code>name</code> method for a particular timezone can return different values. When testing the Brisbane time zone, my device returns <code>@"Australia/Brisbane"</code> whereas another user's device returns <code>"Etc/GMT-10"</code>. Both iPhone's are running 3.1.2.</p>
  
  <p>The <a href="http://developer.apple.com/IPhone/library/documentation/Cocoa/Conceptual/DatesAndTimes/Articles/dtTimeZones.html#//apple_ref/doc/uid/20000185" rel="nofollow noreferrer">Date and Time Programming Guide for Cocoa</a> states that:</p>
  
  <blockquote>
    <p><strong>timeZoneWithName</strong>: The name passed to this method may be in any of the
    formats understood by the system, for
    example EST, Etc/GMT-2,
    America/Argentina/Buenos_Aires,
    Europe/Monaco, or US/Pacific, as shown
    in the following code fragment.</p>
  </blockquote>
  
  <p>I'd just like to know what could determine which value is used? The device? The language?</p>
