I thing better is use some cast method instead cast by function call:

test=# SELECT CAST( now() AS date ), now()::date, 'now'::date::timestamp;
now | now | timestamptz
------------+------------+------------------------
2002-03-27 | 2002-03-27 | 2002-03-27 00:00:00+01
(1 row)

test=# select date '1998-02-24' + time '23:07';
?column?
---------------------
1998-02-24 23:07:00
(1 row)

test=# select timestamp '1998-02-24 23:07';
timestamptz
------------------------
1998-02-24 23:07:00+01
(1 row)
