Quick Way To Startup: Network Time Protocol (NTP) Services
The following demonstrates how to enable the NTP service at boot time and start the NTP service at a shell prompt.
Example:
Managing The: "ntpd" Service
  [root@probe ~]# systemctl enable ntpd.service
  ln -s '/lib/systemd/system/ntpd.service' '/etc/systemd/system/multi-user.target.wants/ntpd.service'
[root@probe ~]# systemctl start ntpd.service
  [root@probe ~]# ntpq -pn
  remote refid st t when poll reach delay offset jitter ============================================================================== 88.198.18.245 6.146.224.0 3 u 5 64 1 113.915 68.354 0.002 24.123.214.97 129.6.15.29 2 u 4 64 1 73.682 38.248 0.002 62.112.194.64 193.67.79.202 2 u 3 64 1 128.611 -19.668 0.002
[root@probe ~]# 
Alternatively, you can use the chronyd service for time synchronization. The following example enables and starts the chronyd service:
Managing The: "cronyd" Service
  [root@probe ~]# systemctl enable chronyd.service
  ln -s '/lib/systemd/system/chronyd.service' '/etc/systemd/system/multi-user.target.wants/chronyd.service'
[root@probe ~]# systemctl start chronyd.service
  [root@probe ~]# 
The NST Web User Interface provides many web pages with additional information and tools to manage time related services. From the main NST WUI menu bar, select: System | Time Management.
