Look in /etc/dhcpcd/dhcpcd-eth0.info to see if the ntp server is provided by dhcp > NTPSERVERS=194.159.73.44 > just browsing through all of /etc/dhcpcd/*info for that line might be > enough.....
Note that for dhclient the file loc changes...
What is the new location?

The dhclient path is /var/lib/dhcp/ and then the file is called dhclient-<interface>.leases.
If given NTP servers, dhclient writes ntp.conf directly (in recent packages). There's really no part for redhat-config-date to play in that.
