In this case, ntpdate is not doing the syncing, you are doing it
manually with your cron job and hwclock call.

Why don't you just run ntpd on the one machine that talks to the higher
stratum servers and use ntpdate for your internal network?

Yes it works for you, but think about the admin running the time servers
that your box connects to. Would this solution be acceptable to them?
Can you imagine 100 if people did the same thing?

Unless you are paying whoever runs the time server, or you both are part
of the same organization, then they are providing you with a public
service, and the least you can do is be kind and help reduce the load on
their servers.
