It seems like as of PHP 5.5, creating a new DateTimeZone with a string like 'EDT' will cause DateTimeZone::getName() to return 'EDT' whereas prior to 5.5 it would convert it would have returned 'America/New_York'

This is of particular note when using a DateTimeZone object to change the timezone on a DateTime object. Using a DateTimeZone object when set as shown above will cause the conversion to be wrong without throwing any errors.
