Nothing to do with the scheduler timing, and nothing to do with NB5.  

The NetBackup System Administrator's Guide Vol 1, since at least 5.x (I
don't have a 4.5 manual to check) have _clearly_ stated that a time
window which spans midnight is considered two separate days, and pointed
out what will happen the _first_ time a midnight-spanning schedule runs
(once at window-opening time and once post-midnight the next day), and
that "[t]he backups will continue to run soon after midnight from that
time forward."  See the heading "How Calendar Scheduling Interacts with
Daily Windows" in all manual releases.

I didn't expect this behavior when calendar-based scheduling first came
out in 4.5, but it works the way the documentation says it will.  Me,
I've been thinking frequency-based since I moved to a NetBackup shop in
3.1 days and rarely have any use for calanedar-based scheduling.  If I
did, I'd lobby for a user-defined day.
