Description:
------------
The timezone_identifiers_list() does not list aliases, even though they are listed on http://php.net/manual/en/timezones.php and they work if you try to create a date with them.

It should include all timezones, even aliases.

Test script:
---------------
<?
new DateTimeZone("Asia/Tel_Aviv"); //works fine
new DateTimeZone("America/Porto_Acre"); //works fine
new DateTimeZone("America/Montreal"); //works fine

var_dump(in_array("Asia/Tel_Aviv", timezone_identifiers_list())); //false
var_dump(in_array("America/Porto_Acre", timezone_identifiers_list())); //false
var_dump(in_array("America/Montreal", timezone_identifiers_list())); //false

//Those are alias to these:
var_dump(in_array("Asia/Jerusalem", timezone_identifiers_list())); //true
var_dump(in_array("America/Rio_Branco", timezone_identifiers_list())); //true
var_dump(in_array("America/Toronto", timezone_identifiers_list())); //true

This is not a bug, these zones are available, but because they are deprecated, they do not *by default* show up in timezone_identifiers_list(). If you want them to show up, you need to specify the DateTimeZone::ALL_WITH_BC constant as first argument to that function to get the deprecated zones included as well.
