I believe ntp4 will work there, and if it does not and somebody opens a bug

I mostly agree with you here, more in a bit...

I think you are talking about one of my pet peeves:


I strongly believe that we should implement something like this.

It will need to be implemented in a way that Dave can tolerate.

The odds of this being implemented are directly proportional to somebody
doing the work.

Near as I can tell, the best way to have somebody do the work is to have
money available to pay for the work to be done.

The best way I know to get money to pay for this work to be done is to show
organizations that by joining the NTP Forum they will be spending money to
get significant value in return.

I believe projects like this one are one example of that "significant
