Date stamps in your serial numbers are useful for people who don't have
access to your version control files. For instance, any of us can do:

dig . soa

and find out when the root zone was last updated. While this is hardly
critical, it can be helpful to third parties.

It's also nice even for the zone administrators, if they happen to be
off-site.
