<https://man.netbsd.org/timeval.3> says struct bintime is meant to be used in 
the kernel only.

I wonder how a nanosecond-resolution timestamp would be converted to bintime and 
back without rounding error, given that the usual tradition in timestamp 
conversion is to truncate toward minus infinity instead of rounding.

The Gnulib time-parsing function sticks with struct timespec, since that's what 
POSIXish APIs give us.
