This small and simple standalone patch extracted from the SQL/JSON work
would allow the user to supply a string with a time zone specified as
hh:mm thus:

SELECT to_timestamp('2011-12-18 11:38 -05:20', 'YYYY-MM-DD HH12:MI
TZH:TZM');
         to_timestamp        
------------------------------
 Sun Dec 18 08:58:00 2011 PST

The patch seems pretty straightforward to me, and it's required for the
jsonpath patches which would be the next cab off the rank in the
SQL/JSON work.

It seems like something worth having quite independently of the SQL/JSON
stuff anyway.

cheers
