        Interesting -- using same version of "hwclock" & same
kernel version, I compared 3 machines:
one machine averaged around -0.988xxx, another -0.991xxx
and a third at -0.0003xx.  (the xxx digits are variable, the listed
digits were mostly fixed values after the loop start).

        Their HW varies considerably, the first two about 5-6 years old,
the latter more recent.  I wonder why they cluster like they do -- the
first two around -1, and the newer one nearer 0.

        Curious...
