NTPD is a "slow starter"! Ideally, you will only start it once and
let it run for a few months.
How slow is a "slow start"?. It can take NTPD up to ten hours to
synchronize within + or - 50 nanoseconds with whatever you are using as
It will never get to within 50nsec. The interrupt processing is far more
variable than that. You might get to withing a few micro seconds.
On a recent restart from cold, the server here took about 15 minutes to
get to within 250 microseconds, and about an hour to be within 10
microseconds. Ultimately it is within about 3 microseconds.
