Hi, Harlan: This problem has been resolved. It's still the KoD that caused it. This command " sntp -d -S -K /dev/null 10.204.134.250" works since the "-K /dev/null" disables the KoD storage. Thank you still the same.

After a while, the date is still not synced. By the way, when I set my own pc's date to an incorrect date, then use the "/usr/sbin/sntp -s -l /tmp/sntp.log 10.204.134.250", the time is synced to the right time very quickly. I used sntp because this is early requirement from customers, ntpd, ntpdate also used and these are alternative, we need to make sure all of them work.

The correction is underway, but a 500ppm slew corrects a 1 second change in about 33 minutes. So it's gonna take a while. I'm not sure why you're using sntp instead of running ntpd, but you might want to use -Ss instead. H -- > I used the sntp command. > > > Can anyone helps me with that? Appreciate it.
