ntpdate with the
-q option (query only, don’t set date) we can validate the server is returning a proper answer:
jemurray@home-server:~$ ntpdate -q pool.ntp.org server 220.127.116.11, stratum 1, offset 0.003985, delay 0.04179 server 18.104.22.168, stratum 2, offset 0.002441, delay 0.05338 server 22.214.171.124, stratum 2, offset 0.000726, delay 0.09357 server 126.96.36.199, stratum 2, offset -0.004938, delay 0.07932 13 Jul 09:42:28 ntpdate: adjust time server 188.8.131.52 offset 0.003985 sec
