This commit adds tests in select places to ensure that these date/time related functions continue to behave as expected when the `timezone_string` option is set to an outdated/deprecated timezone name. The timezone string used in these tests, `America/Buenos_Aires`, is a timezone string which was already deprecated in PHP 5.6.20 (the current minimum PHP version), so using this timezone string, we can safely test the handling of deprecated timezone names on all supported PHP versions. See: [https://3v4l.org/Holsr#v5.6.20 timezone_identifiers_list() output for PHP 5.6.20]. Follow-up to [54207], [54217], [54227], [54229]. Props jrf, costdev. See #56468. git-svn-id: https://develop.svn.wordpress.org/trunk@54230 602fd350-edb4-49c9-b593-d223f7449a82
