NTP

Network Time Protocol (NTP) server is used to obtain the correct time from an external time source and adjust the local time in each connected device. When the NTP server functionality is enabled, the NTP server starts listening on the NTP port for client requests and responds with the reference time. The platform on which XCO is installed must use the same NTP or must be synchronized to the correct time and timezone.

Correct time and timezone ensure the following:

• Self-signed certificates have valid start and expiration times.
• XCO logs have the correct time stamp.
• K3s service starts without errors.

You can edit the /etc/systemd/timesyncd.conf file to select NTP servers in the [Time] section of the configuration file. The NTP= option takes a space-separated list of host names or IP addresses. Ensure that you select at least three NTP servers from the publicly available servers or the internal NTP servers.

```bash
sudo vim /etc/systemd/timesyncd.conf
sudo service systemd-timesyncd restart
systemctl status systemd-timesyncd
sudo timedatectl set-timezone <your\_time\_zone>
