Hi Kevin,
Thanks for the response. I am a little embarrassed and I was in fact hoping
that my stupid Report would just dissolve away in the abyss. In your
responding I am of course quite bowled over that - Hey there are people
genuinely out there - unlike reports one may send to mickeysoft who are
probably paid handsomely.
You are of course right. I do not know what I was seeing - might have been
something to do with it being about 3:00am my time.
Interesting that 24:00 is accepted by Postgres. Didn't know that.
Again, Thank you for the effort you have expended to look into my (really
stupid) bug report.
Regards
Lee

I just wanted to point out that midnight is supported at both ends -- the
start of the day as 00:00:00, and the end of the day as 24:00:00. Perhaps
the application software is not distinguishing these?
Modifying Tom's example to insert one more row, you will see:
f1
----------
00:00:00
01:00:00
02:00:00
23:00:00
23:25:59
24:00:00
(6 rows)
I know there are some who require this behavior. (I had to add it to a
database product years ago when it was used to develop an application for
fire departments.)
