[Veritas-bu] bpsched -predict makes no sense!

Trying to create a dynamic checklist for our Operations group so that they
can go out and check off the backups that were supposed to run.  I want to
create the list on a daily basis with no manual intervention-this way if
I've suspended backups for any reason the change is reflected on the list.

Running bpsched -predict just doesn't work properly.  Here's some sample
output:

Only backups starting after 16:00 are reflected.  But now here's something
else interesting:

bpsched -predict 12/08/01 10:00:00

It displays a whole slew of 09:00 backups, plus one from the previous night.
And when I run the following, I get even different results:

3  cmserver1.backup-int  Weekly_OS  weekly_full  FULL  Saturday   09:00:00

I thought that maybe it was only reporting on 12 hour blocks based on time
specified, but that's not the case.  When I run the same command for 19:00,
the 09:00 backups drop off.  When I run 23:59:59, the 12:00 backups still
show.

I'm at a loss, I've been unable to figure out how bpsched runs the
prediction.  I also don't understand why, out of all the NBU commands out
there, bpsched -predict doesn't allow you to input a start and end time for
the window you'd like to view...

Any help you can give would be appreciated.
