What is this code good for?
Nothing. Thanks, good catch. That code came from this FreeBSD man page:
https://www.freebsd.org/cgi/man.cgi?query=nanotime&manpath=FreeBSD+11.2-RELEASE+and+Ports
an earlier version of which I misread long ago as specifying a way to
get nanosecond-resolution timestamps on FreeBSD variants that did not
support clock_gettime. The man page documents FreeBSD internals; I
misread it as documenting the C library. macOS (or whatever its name was
back then) was the example that I was thinking of at the time; it did
not support clock_gettime until 10.12 if
<https://github.com/zeromq/libzmq/issues/2175> is to be believed.
I installed the attached two patches; the first fixes the problem you
raised, and the second attempts to document the version 10.12 business
better.
