Of course I am aware that POSIX isn't the one true operating system 
specification. But it certainly is a specification. And for a very large 
number of people in the world, POSIX conformity is more important than 
the UTC specification. I agree that POSIX was wrong, but it is what it 
is. What is the "right thing to do" if you have two conflicting standards?
