[SQL] convert timezone to string ...

[Marc G. Fournier]

I know that the server knows that ADT == -0400, and AST == -0300 ... is 
there any way of reversing that?  Basically, I want to say:

SELECT timezone_str(-0400, 'not dst');

and have it return ADT ... I've got a method of doing it right now, using 
a function, but just find it looks so messy, just wondering if there is a 
clean way of doing it ...

Thanks ...
