I wasn't suggesting that he do it for dynamic updates.
I was just giving that as an example of how you might get that many
updates :)

Sure you can.
Simply stop named, edit the file, and restart -- which *could* be done
automatically at midnight if you wanted to.
Again, I'm not suggesting that at all -- just that's it's possible.

If you're using DHCP you are best served using straight integers
starting from
whatever point yu choose anyway. Trying to force a CCYYMMDDuu scheme
onto a dynamic zone sounds like a recipe for at least a nightmare, if
not disaster..
I'm not even sure that it is currently possible to dictate the format of
the serial number
that results from an update..
