note 8991 added to date

Under Solaris (and possibly other systems), the function call date("Z"); will return positive offsets only. If you are in CST (-6), it will return 21600 instead of -21600. It has to do with Solaris's time structure not having "tm_gmtoff", so it just assumes that it's positive. I am unable to find a way to figure out if the time zone on a Solaris machine should be inverted instead of left alone? I am looking for a way to do it without the user setting a variable, without recompiling PHP, and without too much mess. http://www.php.net/manual/function.date.php
