I'd be waiting for minutes if I waited till ntpd decided it had a
"good enough" estimate of the Motorola Oncore's time. Ntpd *could*
have its first time estimate accurate to well under 1ms in half a
second on average. The problem is, it won't tell you the time or step
the system clock until it filters the crap out of the refclock signal.
Ntpd has a hard act to follow. The old ntpdate program was a near
ideal solution from the perspective of booting. It did its job
quickly and got off the pot.
