If it goes longer than a day then something is wrong.  It isn't
that hard to check every delegation NS RRset and every glue RRset
daily.  It isn't that hard to put those that are inconsistent onto
a list to perform a recheck the next day and if they are still
inconsistent send a email to the zone contacts.  As this is the
registry they should have valid contact details or the registrar
should and can act as their proxy.

And the point of having the registry check is to catch errors.  They
can then send email reminders.
