NTP server and the synchronization period

General discussion
1

I have set the following NTP servers according to the response.

ntp.globe.cz - 13 ms
0.openwrt.pool.ntp.org - 13 ms
3.openwrt.pool.ntp.org - 17 ms
ntp.nic.cz - 22 ms

What would be a reasonable period of router time synchronization, that it was not often unnecessarily or too long period. My estimation of the suitable period is 6 to 48 hours

Simply leave the ntpd running, it has it’s own algorithm for calculating synchronisation period.

Or is there some option to change synchronisation period?

Unfortunately Omnia doesn’t use ntpd as a default but ntpclient.

Oops, ntpclient package shouldn’t be installed at all. There is already busybox-ntpd, which acts more like NTP daemon. Running NTP client together with NTP daemon is not good.

I’ve created an issue for that. In the meantime, you can force uninstall ntpclient by adding this line to /etc/update/user.lua:

Uninstall "luci-app-ntpc" {priority=60}

You can set up the NTP servers set in LuCI using System - System control panel.
