Wow.  You must have gotten those with the help of some arithmetic,
because timestamptzin would never have produced them.  I found out I can
do

regression=# select extract(epoch from ('2000-01-01 00:00:00'::timestamptz +
'0.00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001'::interval)
-'2000-01-01 00:00:00'); 
 date_part
-----------
    1e-209
(1 row)

but I wonder what it was you actually did.
