How does the SmartServer use a SNTP server to do Time Syncing (KB1410)

The SmartServer IOT uses the default ubuntu Simple Network Time Protocol (SNTP) server 

 ntp.ubuntu.com

 

For sites where the SmartServer may not have internet access you can do one of the following to point to local SNTP server:

 

1. Change the default SNTP server in the SmartServer, but this will have to be re-done after every software upgrade/re-image.

Edit the following file and change line 15 with the IP address of the local SNTP server and do a reboot

/etc/systemd/timesyncd.conf

 

2. If a dhcp server is in use, the simplest way is to add the ntp-server option to the dhcp server, which will override the default, and is impervious to upgrades/re-image.
