According to ntp(8), -q makes ntpd exits just after the first time the
clock is set.
Doesn't this mean if ntpd_sync_on_start is on and the time difference is large,
then ntpd will exit after the first time sync? Is this the behavior we
really want?
Shouldn't we keep ntp running after the clock is adjusted?
