The only thing that you can conclude from the referenced paper is that
for very short measurement intervals, order of a second, the noise
process is white phase. Obviously a simple average is optimal to
determine the time from a group of such closely spaced measurements.

This may sound like an embarrassment of riches, but here is my problem:
I have some rack-mounted servers (IBM System x3650 to be precise) that I
need to synchronize with a PPS signal. The problem is, of course, that
the machines have only one serial port, which I want to use as a serial
consol
