title: What's the point of using wordy Time Zones?
body: <p>I know this isn't specific to PHP, but what's the point of using timezones listed like this :<a href="http://us2.php.net/manual/en/timezones.america.php" rel="nofollow noreferrer">http://us2.php.net/manual/en/timezones.america.php</a>?  For example "America/Indianapolis" and  "America/New_York".  What is the problem with EST, EDT, CST, CDT, &amp;c?</p>
