Set Server Time

1. Log in as root.
2. Check if the current server time reflects the local time zone using the date command, as follows.

date

3. To check for a nearby city with the correct time zone, use the timedatectl list-timezones command.

For example, the following command finds time zones in Asia:

timedatectl list-timezones | grep Asia

4. To change the server time to local time, use the timedatectl set-timezone command.

Example:

timedatectl set-timezone Asia/Singapore

5. To make sure that the server time has changed, enter the following command:

ls -l /etc/localtime

1. Log in as root.
2. Check if chrony daemon is running. Enter:

systemctl status chronyd

3. If the result from the previous command shows inactive or dead, enable the chrony daemon. Enter:

systemctl enable chronyd

4. To start the daemon, enter:

systemctl start chronyd

5. Edit /etc/chrony.conf using vi. Enter:

vi /etc/chrony.conf

6. Replace the default NTP server settings to the local NTP server.

Original default settings:

server 0.centos.pool.ntp.org iburst

server 1.centos.pool.ntp.org iburst

server 2.centos.pool.ntp.org iburst

server 3.centos.pool.ntp.org iburst

Settings to use local NTP server(s):

server 192.168.1.1 iburst

server 192.168.1.2 iburst

7. To save the file, enter:

:wq!

8. To restart the chrony daemon, enter:

systemctl restart chronyd

9. Check the health of the local time server as follows.

timedatectl

10. To make sure that DRAGEN Server can synchronize with the local NTP server, use one of the following commands:
• chronyc tracking (Manual)
• ntpdate (Automatic)

The following is an example command:

ntpdate -q 192.168.1.1
