Using a local Network Time server (NTP)
Ardexa Linux uses systemctl-timesyncd for clock synchronisation. This will be autmatically done. For troubleshhoting, or to configure one or more local, custom NTP servers, first scan the local network for port 23/udp
sudo nmap -sU -p 123
Next, edit the file /etc/systemd/timesyncd.conf and add a space separated list of IP address for each of the NTP servers to the NTP key, e.g.
Finally, restart the service to activate the new NTP servers and then check the status. If the timezone is changed on the edge device; make sure the device METADATA is refresh when the timezone is changed.
sudo systemctl restart systemd-timesyncd
timedatectl timesync-status
