You need drift correction implemented in the kernel to get decent
timekeeping. ntp_adjtime is just the API.
I'd be happy to assume we have drift correction. If not, there is no point
in running ntpd. Just run sntp occasionally. I don't think we should
require ntp_adjtime as the API,
OpenBSD has adjfreq.
adjfreq(const int64_t *freq, int64_t *oldfreq);
I thought I fixed things to use it, but I can't find any references to it so
I don't know what's going on.
