Here's another solution that you can use: Configure the currently
unsynchronized master to use its local clock as a ref-clock. Then the
master will be able to claim that it is synchronized to _something_ and
ntpdate will be happy.

Add this to the ntp.conf on the currently unsynchronized master:

fudge stratum 10

Keep in mind that it will take ~8 minutes for ntpd to "synchronize"
its self to the LocalCLK.
