I found so same idea was discussed three years ago

http://www.postgresql.org/message-id/14107.1276443739@sss.pgh.pa.us

and it is a part of our ToDo: "Add function to allow the creation of
timestamps using parameters"

so we can have a functions with signatures

CREATE OR REPLACE FUNCTION construct_date(year int, month int DEFAULT
1, day int DEFAULT 1) RETURNS date;
CREATE OR REPLACE FUNCTION construct_time(hour int DEFAULT 0, mi int
DEFAULT 0, sec int DEFAULT 0, ms float DEFAULT 0.0);
CREATE OR REPLACE FUNCTION construct_timestap(year int, month int DEFAULT ....
CREATE OR REPLACE FUNCTION construct_timestamp_with_timezone(year int,
month int DEFAULT1, ...
