I am not so interested in performance optimizations, but do I think offering time in nanoseconds is attractive from an application point of view. The timespec is impractical for everyone.
While you are at it with new syscalls, why not make a clean break from POSIX and fix the uglies?
- New name, to distance ourselves from POSIX (clock_ns_get?) - Family of calls, with set/get - Sub nanosecond field - TAI time base (or according to parameter?)
Thanks, Richard
