[php-src] Issue #10765: setcookie() negative timestamp

Issue: https://github.com/php/php-src/issues/10765 Author: Erwane ### Description The following code: ```php <?php declare(strict_types=1); date_default_timezone_set('UTC'); setcookie('old_timestamp', 'my value', 1); setcookie('negative_timestamp', 'my value', -1); ``` Resulted in this output: ``` HTTP/1.1 200 OK Host: localhost:8000 Date: Fri, 03 Mar 2023 17:33:45 GMT Connection: close X-Powered-By: PHP/7.4.33 Set-Cookie: old_timestamp=my%20value; expires=Thu, 01-Jan-1970 00:00:01 GMT; Max-Age=0 Set-Cookie: negative_timestamp=my%20value Content-type: text/html; charset=UTF-8 ``` But I expected this output instead: ``` HTTP/1.1 200 OK Host: localhost:8000 Date: Fri, 03 Mar 2023 17:33:45 GMT Connection: close X-Powered-By: PHP/7.4.33 Set-Cookie: old_timestamp=my%20value; expires=Thu, 01-Jan-1970 00:00:01 GMT; Max-Age=0 Set-Cookie: negative_timestamp=my%20value; expires=Wed, 31-Dec-1969 23:59:59 GMT; Max-Age=0 Content-type: text/html; charset=UTF-8 ``` (I'm really not sure about the expires=Wed, 31-Dec-1969 23:59:59 GMT. Maybe if expires is negative, force to 1 ? Same with php8.1 ``` HTTP/1.1 200 OK Host: localhost:8000 Date: Fri, 03 Mar 2023 17:47:04 GMT Connection: close X-Powered-By: PHP/8.1.16 Set-Cookie: old_timestamp=my%20value; expires=Thu, 01-Jan-1970 00:00:01 GMT; Max-Age=0 Set-Cookie: negative_timestamp=my%20value Content-type: text/html; charset=UTF-8 ``` Thanks. ### PHP Version ^7.4 || ^8.1 ### Operating System _No response_
