Hi and welcome. It’s normal to see unsynchronized messages when ntpd starts up. What does “ntpq -c peers” report after ntpd has been running for at least 10 minutes? ---

hi @elljay after 10 min clock is in unsynchronized state, could you please suggest more specific to debug ---

Hi, please can you post the output of “ntpq -c peers” so we can see how many peers you have configured and whether they are reachable etc. ---

Hi, just one remote server is too little for ntpd to adjust the clock and be confident that the time is right. Ntpd needs at least 3 servers to be sure of the correct time, before setting and adjusting the clock and distributing time. With 3 servers ntpd can vote out a “false ticker”. Segal’s Law: " A man with a watch knows what time it is. A man with two watches is never sure." Configure 3 - 7 servers and then ntpd should stop the alert. ---

If you keep the ntpd running further, does it still report `Clock Unsynchronized` error time to time later on? ---

Or run “ntpq -c rv”. In the first line of the output, you should see `clock_sync` if the clock is synchronized. A full description of the first line of the output can be found here: [http://www.eecis.udel.edu/~mills/ntp/html/decode.html#sys](http://www.eecis.udel.edu/~mills/ntp/html/decode.html#sys) ---
