I just wanted to point out that midnight is supported at both ends -- the s=
tart of the day as 00:00:00, and the end of the day as 24:00:00.  Perhaps t=
he application software is not distinguishing these?

Modifying Tom's example to insert one more row, you will see:
=20
    f1
----------
 00:00:00
 01:00:00
 02:00:00
 23:00:00
 23:25:59
 24:00:00
(6 rows)
=20
I know there are some who require this behavior.  (I had to add it to a dat=
abase product years ago when it was used to develop an application for fire=
 departments.)
