I am using a embedded board which runs a DHCP client with systemd-networkd service. Here I have requirement to fetch ntp server with option 42 and synchronize time from it for every 32 seconds. I was able to do this with systemd-networkd and systemd-timesyncd service. Currently my issue is time is syncing with server only at the start up / reboot , if I modify the time in ntp server I do not see any change in the client until I reboot. Also status of systemd-timesyncd service shows idle.

I tried to set RootDistanceMaxSec=5 , PollIntervalMinSec=32 in timesyncd.conf but nothing seems to work.

Any suggestions on this is much appreciated.

Thanks,

That is how it should be!

A well designed NTP client stops trusting an NTP server when the server proves to be erratic / unreliable.
