I know that I can it with time with time zone. What I cannot do with
is, timestamp with time zone.

test=# \d t1
Table "public.t1"
Column | Type | Modifiers
--------+--------------------------+-----------
t | timestamp with time zone |

test=# insert into t1 values('2007-12-13 12:34:56 +0400');
INSERT 0 1
test=# select * from t1;
t
------------------------
2007-12-13 17:34:56+09
(1 row)

Can I get "+04" without knowing that I inserted the data using "+0400"
time zone?
