[GENERAL] Is there a better way to do this?

[Wei Weng]

Hi all

I want to implement something like the following:
CREATE OR REPLACE FUNCTION AddDays
       (TIMESTAMP WITHOUT TIME ZONE
       , INT)
RETURNS TIMESTAMP WITHOUT TIME ZONE AS '
DECLARE
       time ALIAS FOR $1;
       days ALIAS FOR $2;
BEGIN
       RETURN time+days*24*3600*''1 second''::INTERVAL;
END;
' LANGUAGE 'plpgsql';

Basically the function takes two parameters, and add the second one (as 
days) onto the first one (as timestamp without  timezone)
I don't really like this implementation. Is there a more concise way to 
do this?

Thanks

Wei
