Begin rant:

From someone who is currently battling a fresh jessie install that didn't 
even come with ntpdate installed, and which using the above format 
in /etc/ntp.conf is still about 12 hours off on an rpi-3.

Installing ntpdate and attempting to start it gets me a no servers found 
message, yet they are defined as discussed above, and the network is 
fully accessible to all other forms of communication.  

That doc on www.ntp.org is nice, but worthless to someone who just wants 
it to work. I have quite a zoo of machines here, and I see little 
advantage to each one banging on a network server, when it needs an 
update.  But does it give even a hint of how to make this machine, or 
heaven forbid, my router, which keeps time via ntp, and which I believe 
has the time broadcast enabled, (its dd-wrt in a buffalo box) into a 
server that the rest of my machines can listen to to get the correct 
time. If I could achieve that, it would reduce the loading on the time 
servers at debian or pool.ntp.org by a factor of 5 or 6 just from my 
home network.

But a manpage that actually tells us how to do that must be sick bird, 
because its not been written yet.  Man page writers please get real, and 
tell us how to do something like getting our home networks all 
synchronized to our routers which can then broadcast it to the rest of 
our network.

Such a scheme can easily keep us on time with any errors within a few 
milliseconds, more than adequate enough for the girls I go with. While 
reducing the load on the servers by at least 80%.

So how about a manpage that tells us how to do that?  If its not illegal 
according to some rfc that is.

Rant off.

Thanks for reading.
