This is a Dell Precision T3500 workstation Can you please attach /etc/ntp.conf as created by system-config-date and output of "ntpq -pn" command? Created attachment 416391 [details]
/etc/ntp.conf
[root@savannah-test ~]# ntpq -pn
remote refid st t when poll reach delay offset jitter
==============================================================================

Zeroes in the reach column means that there were no responses from the NTP servers. This is usually a firewall issue. If a list of NTP servers is provided by DHCP in your local network, you may be hitting bug #591140. even after stopping iptables service, reach is zero.
