Not that complex though, it's only a matter of iterating through $_COOKIE
and resetting each one with a known expiry time (strtotime("+10 minutes
and 20 seconds")). You could do this in a single file and automatically
use it on every page using php_value auto_prepend_file in the Apache
virtualhost.

It's not really strange, if you examine the HTTP spec (or watch HTTP
headers using Firefox's Live HTTP Headers) you'll find the browser doesn't
send back the expiry date to the server, only the name and value.
Therefore it's not strange that PHP can't obtain the information, it's
never told (and it can't just remember what it set because it could have
been changed with Javascript or by editing the cookies.txt file).

You're welcome.
