NTP can already report jitter and offset values. Maybe what we need is a
way to have those values *reduce* the precision of the kernel-provided
nsec timestamps, so that you get timestamps as accurate as possible for
your timebase, but no more accurate? (Of course, if the jitter changes a
lot, interesting things may happen, but that's quite rare.)

Note that no linux filesystem has time resolution better than a jiffy. (The on-disc format may use nanoseconds, but the mtime/ctime/atime aren't updated using a nanosecond-precision time source.)
