I have been unable to get the time to sync on my MangOH Green board.
I have it connected to the internet via ethernet, and everything I’ve read indicates that perhaps the reason is that because the built in time sync relies on cellular network.
Even when I ssh in and run “ntpd -q -p pool.ntp.org”, the time remains incorrect, despite the command not showing any error or output.
Some changes is needed to make update via NTP over Ethernet automatically.
For the manual command, just tested and it works for me to update time over Ethernet.
root@swi-mdm9x15:~# ntpd -q -p pool.ntp.org

Any chance the NTP server is not accessible or blocked by network gateway or firewall?
One bad thing about “ntpd” tool is that it does not return the execution result, tcpdump capture may help to check further.
