FreeBSD Security Advisory FreeBSD-SA-16:16.ntp

[Roger Marquis]

Large builds over NFS filesystems, particularly secure NFS (i.e.,
Kerberos) are one the best tests of time synchronization.  Clients with
bad clocks can further exercise this not uncommon infrastructure. The
reason you don't typically see build errors even here, IME, is because
the timehosts tend to be shared by and local to both client and server.
