This statement seems to be implying that ntpd does not detect interface
changes. This is *NOT* the case for 4.2.4 and after. ntpd 4.2.4
*detects* changes in interface addresses and routing. I may take a while
platforms (Windows/Linux - BSD is almost instant as it is event driven).
The default rescans every 5 minutes. This can be lowered to 1 minute
with the -U 60 switch. -U 0 disables scanning. The lower limit of 60
seconds will be dropped in the future. The default where choosen for
a reasonable balance between computational load and responsiveness.
Thus don't expect an instant response when you are on a platform where
we have yet to implement the event mechanism. Just wait a bit.
It is documented in the html pages an in the short help of the daemon.
