On SLES 12, I ran a '/usr/sbin/sntp -P no -r xx.xx.xx.xx' command to sync my system clock with the ntp server, it returned '/usr/sbin/sntp: illegal option -- P'.
The version of sntp - standard Simple Network Time Protocol program - Ver. 4.2.6p5
While the same command work well on SLES11. Could any having the knowledge help me out of the question please?
