What purpose is there to recording timestamps in nanoseconds? For clocks that start when the process starts running, float is (basically) good enough. For measuring e.g. file access times, there is no way that the actual time is know with anything like that precision (even if it is recorded as a number of milliseconds -- that's a different issue).

The number one use case, as far as I understand, is to have bit-identical file modification timestamps where it can matter. I agree that the rest is anecdotical.
