now() and date_trunc() apparently corrupting data

This is with -configure -enable-integer-datetime in 7.3.2, i386 Linux
platform. Is anyone else seeing this? If so, does it happen without
--enable-integer-datetime?

junk=# \d mt
Table "public.mt"
Column | Type | Modifiers
--------+---------------------+-----------
v | time with time zone |

junk=# delete from mt;
DELETE 4
junk=# insert into mt values ('06:25');
INSERT 12554249 1
junk=# select * from mt;
v
-------------
06:25:00+00
(1 row)

junk=# select * from mt where v < now();
v
-------------
00:00:00+00 <-- data has been changed...
(1 row)

junk=# select * from mt;
v
-------------
00:00:00+00 <-- ...permanently, it seems.
(1 row)

The same seems to happen with date_trunc()
