Sure! On my laptop the output is: $ ntpdate -q 127.0.0.1 server 127.0.0.1, stratum 3, offset -0.000012, delay 0.02565 5 May 19:22:28 ntpdate[5000]: adjust time server 127.0.0.1 offset -0.000012 sec and $ ntpdate -q 134.58.255.1 server 134.58.255.1, stratum 2, offset -0.000195, delay 0.02599 5 May 19:22:57 ntpdate[5001]: adjust time server 134.58.255.1 offset -0.000195 sec where 134.58.255.1 is the server ip.
