You don't want to. Really.

Right. One second resolution and limited range was considered a problem.

I would suggest using the native timestamp type. You can convert back
and forth using various techniques, but you should find that the
examples below give you a good start:

lockhart=# select date_part('epoch',timestamp 'now');
 date_part
-----------
 997993780

lockhart=# select timestamp(integer '997993780');
       timestamp
------------------------
 2001-08-16 20:29:40+00
