Yes, the "-d" can be removed. Well, the command " sntp -d -S 10.204.134.250" does work well and return status is 0 and time synced, but it gives a warning about the koD file. When I said this command didn't work before, it was because I used the command like this " sntp -d 10.204.134.250 -S" instead of " sntp -d -S 10.204.134.250". Note that the position of "-S" is different. I had thought it was caused by the KoD warning, but I'm wrong. Sorry. It's actually because of the wrong place of "-S".
Well, another problem I should say is: Type " sntp -d -s 10.204.134.250", got following result: "Sntp [email protected]. Fri Feb 17 07:46:31 UTC 2017 (1) Kod_init_kod_db(): Cannot open KoD db file /var/db/ntp-kod: No such file or directory 2-16-01-01 00:07:06.367408 (-0100) +35720777.211043 +/- 23813851.6002329 10.204.134.250 s3 no-leap adj_systime: Invalid argument" Time not synced. Type "sntp -d -S 10.204.134.250", got following result: "Sntp [email protected]. Fri Feb 17 07:46:31 UTC 2017 (1) Kod_init_kod_db(): Cannot open KoD db file /var/db/ntp-kod: No such file or directory 2-16-01-01 00:07:09.367408 (-0100) +35720777.211043 +/- 23813851.6002329 10.204.134.250 s3 no-leap" Time synced. So obviously "-s" doesn't work, "-S" works. My ntp version is 4.2.8p8 I also use another version 4.2.6p5, both -s and -S work well.

The -d should not be needed. What is the return status of the sntp command? If it's 0, it thinks it set the time. If it's 1, there was a problem. If there was a problem, sntp should have written something to the syslog. Is there anything interesting there?
