I have a feeling that it's got something to do with the workaround for
broken mktime() that I recently put in.  Could you try this experiment
and see what you get?  (This should at least tell us whether the
variance from common behavior is on the input side or the output side.)

regression=# set TimeZone TO 'PST8PDT';
SET
regression=# select abstime 'May 10, 1947 23:59:12';       abstime
------------------------1947-05-10 23:59:12-08
(1 row)

regression=# select (abstime 'May 10, 1947 23:59:12')::int4;   int4
-------------714585648
(1 row)
