It seems to me that that case also produces sensible results:
regression=# select 1::abstime::timestamp without time zone ;
timestamp
---------------------
1969-12-31 19:00:01
(1 row)
This corresponds to my local time (EST) at unix timestamp 1, which is
exactly what timestamp without time zone ought to show.
Obviously, which of these you want to use depends on what your goal is,
but they all give useful behaviors IMHO.
