Using NTPd

Install ntp package that provides ntpd daemon.

Install NTPd
dnf install ntp -y

After the installation, you need to edit the /etc/ntp.conf configuration file to add the address of your NTP server.

The server command takes the following syntax;

server address
where address is either the IP or resolvable hostname of the NTP server.

...
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
#pool 2.fedora.pool.ntp.org iburst
server 192.168.43.69 iburst
...

Save the configuration file and restart ntpd daemon.

Verify the connection to the server using the netcat command;

# nc -zuv 192.168.43.69 123
Ncat: Version 7.70 ( https://nmap.org/ncat )
Ncat: Connected to 192.168.43.69:123.
Ncat: UDP packet sent successfully
Ncat: 1 bytes sent, 0 bytes received in 2.01 seconds.

Now that your client can successfully connect to your NTP server, verify that time synchronization is working;

# ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
 192.168.43.69   167.99.82.6      4 u   31   64    7    0.292   67.320  12.531

Using ntpdate

If you want to synchronize the time of your client with NTP server once, you can use ntpdate as follows;

Install ntpdate
dnf install ntpdate -y

Once the installation is done, you can use the ntpdate to synchronize the time as follows;

Start and enable ntpdate

systemctl start ntpdate
systemctl enable ntpdate

To use ntpdate, you need to stop and disable ntpd

systemctl stop ntpd
systemctl disable ntpd

To verify that time synchronization works fine, run ntpdate command as shown below

# ntpdate 192.168.43.69
18 Nov 12:30:02 ntpdate[4983]: step time server 192.168.43.69 offset 3608.684470 sec

Great. That is all it takes to configure local NTP  server on Fedora 29.
