[ntp:questions] Re: ntpd transmit timestamp precision

I see to points Damion has raised where I do not see your response.

The first is that there exist several libraries where the C library provides
the nano calls but implements them using the (older) microsecond
calls. Therefore there is no data available below the microsecond and our
code is not handling this case.

The second point was related to this one, but it escapes me at the moment.

Damion, what does clock_getres() return on these systems?

I need to finish packing for a trip - more later.
