Yes, of course I looked at the patch.  It would change the glibc API in 
an upwards compatible way.  As I wrote, this would require applications 
to change if they want to use the new facility.  That is not "leaving 
things alone".  As already discussed, applications already have a way to 
solve the problem, one that is widely used and portable: they can set TZ 
to "UTC0" (or to whatever other value they like).  We can therefore 
leave things alone; there's no need for an extension.

Again, we are going around in circles.  The 'best fit' is not the TZ 
string at the end of the tzdata file.  It is not any other line from the 
tzdata file.  It is not in the tzdata file anywhere.  You are asking for 
something that does not exist.
