According to the changelog of the NTP package nothing's changed since '04!

 $ rpm -q --changelog ntp | less

"Name or service not known" sounds more like a resolution issue to me.
Do you by any chance have caching-nameserver installed and had
modified /etc/named.conf ? If so a caching-nameserver update may've
overwritten your previous modifcations and potentially have broken

Are you using N.pool.ntp.org in /etc/ntp.conf? Can you resolve those hostnames?

 $ awk '/ntp.org/ { print $NF }' /etc/ntp.conf | xargs -n1 dig +noall +answer
