Hmmmmmm. Not sure that this is the correct solution for your particular
problem (ie. altering the driver) although it may work for you now. It
would be better to find out the core of the problem and fix that.

What database version are you using? What driver version are you using?
I can't figure out how to get 7.2 beta to return a shorter timestamp
then 1970-01-01 00:00:00. even if I insert a short timestamp. I presume
you are using older code? As I said before, the driver should force
the datestyle to ISO when it first gets a connection.

select '1970-1-1 0:0'::timestamp without time zone, '1970-1-1 0:0'::timestamp;
timestamp | timestamptz
---------------------+------------------------
1970-01-01 00:00:00 | 1970-01-01 00:00:00+09
(1 row)

If I can figure out how you are doing it and if the its a problem in the
latest code, then we can fix it.
