here is my solution that works -- Thanks Matthew!:

sudo mkdir -p /etc/NetworkManager/dispatcher.d

sudo vi /etc/NetworkManager/dispatcher.d/ntpd

----

#!/bin/sh

interface=$1
state=$2

case $state in
       up) /sbin/service ntpd start;;
       down) /sbin/service ntpd stop;;
       *) ;;
esac

----

sudo chmod 755 /etc/NetworkManager/dispatcher.d/ntpd


You can see that it can also be tested for interface, so maybe you only 
want to start ntpd when eth0 starts.  What you see here will start and 
stop ntpd on every interface change.
