Re: NTP (not SNTP) on the System i ?

A crazy thought, maybe - I just googled for NTP and AIX - there are both 
client and server in AIX - and PASE is an AIX environment, pretty complete.

I don't know if PASE has the NTP stuff, but it might. Here's a link on 
configuring NTP on AIX 5L - not sure what is the current AIX version of 
PASE.

Here is a discussion of a Java client -

http://stackoverflow.com/questions/925191/java-ntp-client

It mentions a limitation due to clock ticks being not a fine-enough 
measure - on IBM i, we go down to 8 microseconds per tick from long ago 
and 1 microsecond per tick on more recent pre-7.2 and micro-micro (up to 
12 digits precision) on 7.2
