I think we are heading the wrong way on this. It is not an Open
Firmware problem and it is not a Mac problem. I have seen this before
with NTP Classic. I have verified before that Chronyd does not have the
same issue.
There was a time I used to buy and provision 10 identical servers at a
time. Of the 10, one often had this problem. The fix was chrony.
Sometimes the clock needs to be pulled more than ntpd expects and ntpd
gives up just before it succeeds.
I think this is clearly an ntpd bug.
