In fact, I think it's adjusting in exactly the wrong direction.
I get the right number from
regression=# select date_part('epoch', 'today'::timestamp at time zone 'UTC');
date_part
------------
1198022400
(1 row)
and the wrong one from
regression=# select date_part('epoch', 'today'::timestamptz at time zone 'UTC');
date_part
------------
1198058400
(1 row)
and I think the locution with CURRENT_DATE is equivalent to the second
case because timestamptz is the preferred type to promote date to.
