Here in the USA, that is the right answer because 4/2 was a daylight
savings switchover date.  Notice the difference in timezones:

regression=# select '2000-04-03'::timestamp;
        ?column?
------------------------
 2000-04-03 00:00:00-04
(1 row)

regression=# select  '2000-04-02'::timestamp;
        ?column?
------------------------
 2000-04-02 00:00:00-05
(1 row)

If it wasn't a DST change date where you live, then you are running
with the wrong timezone setting...
