Not sure this is how to properly reply to a thread here so hopefully it lands with the original thread.
Someone suggested using the HMC which does support NTP version 4 then sync the System i to the HMC. We did this today, setting up the HMC with multiple NTP servers then did the CHGNTPA and told it to point to the HMC. I guess technically we're still using SNTP on the System i but if we think of the setup as being an HMC and System i as a single platform we can demonstrate the config screen on the HMC then we can show the log file on the System i which clearly shows the tme being adjusted and sync and it includes
NTP" in some of the log messages so this will probably be sufficient.

Subject: Re: NTP (not SNTP) on the System i ?
The problem still is that the protocol is SNTP and not NTP, and that brings us back to the first post. How to get NTP running on the i. PASE? JAVA? etc.

Just go to a green screen type CHGNTPA F4 and fill the parameters.

The i is set up as client and server. The internal users poit to it to
0.pool.ntp.org, 1, 2 are generic NTP servers, you shoulg ping them to
see if they work at your place, otherwise google for NTP servers at

I need to meet a government requirement that says my System i must
use the NTP protocol and set its time. I'm well aware of IBM's
built in support for SNTP but the requirements state that SNTP
("simple" network time
is not sufficient. One of the reasons given is that SNTP allows
you to define multiple time servers on the Internet but it uses a
round robin approach such that if one server is down it goes to the
next. With NTP, apparently multiple servers are considered by the
protocol and it determines which is the most accurate.
We've tried to demonstrate to the governing body the SNTP support
along with the log files it creates as it adjusts the time but
they've justsaid no so we're looking for other ways to implement
NTP on the System i.
Any suggestions anyone?
