What is this code good for?

Nothing. Thanks, good catch. That code came from this FreeBSD man page:


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.
