Hello!
I have four times servers. One of them is till unsynchronized.
Even if I restart the system or process OpenNTPD tries sync and then It's sucessful.
But after some time clock is unsynchronized...
Every my times servers have the same configuration and external time server to sync but I have a problem with one.
The data below represents output of ntpctl and ntpdate commands.
Time server synchronizes and then resynchronizes again and finally is still unsynchronized.
