     What do you mean by "doesn't work?"  (Besides "doesn't compile,"
that is.)  What were you hoping to get, and what did you see, and
in what way did it disappoint you?

     The getTimeZone() method has already parsed the string (or
tried to), and you can extract its results from the TimeZone object.
