Q on a "fix" for Date::TimeZone

I wanted TX to give me the default TZ as set by the server when I did this... $tz = new Date_TimeZone (); So I did this... I modified line 107... function Date_TimeZone($id = NULL) and added this IF block at the top of the method... if ( $id == NULL ) { $this = $this->getDefault(); return $this; } I have 3 questions about this: 1) will this break lot of things? 2) is this not the way to do it? yes, I know about Date_TimeZone::getDefault(). To me 'new TimeZone()' seemed like a logial way to invoke this class and pull the default. 3) if this is kosher, how can I propose a change to the Class to incorporate it? Thanks Walter BTW: I have env 'TZ' set on my windows box and this works fine, as well as on my Linux box.
