Hi,
I have a customer that claims that UCX/NTP does not
operate in the same manner as UNIX/NTP which is quite
posible... The problem he has encountered is the following:
With a time diference of only 7 seconds, a step was
generated rather than drifting. Another occasion was with
a 40 second diference. ( I have not been able to reproduce
this senario)
RFC 1305 indicates that if the magnitude of the apeture
is greater than MAX.CLOCK a step will occur. What is this
number within UCX/NTP?
Thanks,
Mike Lavergne

| 5240.1 | The version of NTP included with UCX is braindead | twick.nio.dec.com::PETTENGILL | mulp | Mon Feb 24 1997 21:44 | 12 |
Since DEC does such a poor job of software engineering, we decided to spend millions on software from other companies. The result has been some really lame software. The NTP included with UCX is one of them. There's a reasonable implementation of NTP v3 available if you search for it; I've posted pointers in a couple of notes here. The best option is to use DECnet-PLUS and DECdts. You can feed into DECdts the time from NTP on a server or two, if you don't have a hardware clock available. DECdts is much easier to setup in LAN than NTP (its basically automatic). And DECnet-PLUS will provide significantly better integration of IP into OpenVMS than any IP implementation alone. | |||||

As per my testing with UCX 4.1, NTP will drift with a time diference of
less than 30 seconds and step starting at 30 seconds.
