horology and time failures on freebsd/alpha

I'm still getting failure, but it gets weirder:

regression=# drop table timetz_tbl;
DROP TABLE
regression=# CREATE TABLE TIMETZ_TBL (f1 time(2) with time zone);

INSERT INTO TIMETZ_TBL VALUES ('00:01 PDT');
CREATE TABLE
regression=#
regression=# INSERT INTO TIMETZ_TBL VALUES ('00:01 PDT');
INSERT INTO TIMETZ_TBL VALUES ('01:00 PDT');
INSERT INTO TIMETZ_TBL VALUES ('02:03 PDT');
INSERT INTO TIMETZ_TBL VALUES ('07:07 PST');
INSERT 154307 1
regression=# INSERT INTO TIMETZ_TBL VALUES ('01:00 PDT');

INSERT INTO TIMETZ_TBL VALUES ('07:07 PST');
INSERT INTO TIMETZ_TBL VALUES ('08:08 EDT');

INSERT 154316 1
regression=# SELECT f1 AS "Time TZ" FROM TIMETZ_TBL;
Time TZ
----------------
00:01:00-07
01:00:00-07
02:03:00-07
07:07:00-08
08:08:00-04
11:59:00-07
12:00:00-07
12:01:00-07
23:59:00-07
23:59:59.99-07
(10 rows)

-- Now run EXACTLY the same query again...

regression=# SELECT f1 AS "Time TZ" FROM TIMETZ_TBL;
Time TZ
----------------
00:00:00-07
00:00:00-07
00:00:00-07
00:00:00-08
00:00:00-04
00:00:00-07
00:00:00-07
00:00:00-07
00:00:00-07
00:00:59.99-07

What the heck!!?!?!?! The SELECT statement has somehow edited the data in
the table or something??? From this point forward, the table is all
stuffed...
