Seems like a significant differences between php 5.3 and 5.6:

php -r "new DateTimeZone( '-0400' );"
-------------                        --------------
- PHP 5.3.3 -                        - PHP 5.6.30 -
-------------                        --------------
DateTimeZone::__construct():        Works as expected.
Unknown or bad timezone (-0400)

php -r '$tz = new DateTimeZone( "EDT" ); echo $tz->getName();';
-------------                        --------------
- PHP 5.3.3 -                        - PHP 5.6.30 -
-------------                        --------------
America/New_York                    EDT

php -r '$tz = new DateTimeZone( "EDT" ); echo $tz->getName();';
-------------                        --------------
- PHP 5.3.3 -                        - PHP 5.6.30 -
-------------                        --------------
DateTimeZone Object                DateTimeZone Object
(                                    (
)                                    [timezone_type] => 2
                                    [timezone] => EDT
                                    )

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.
