NTP packages (was: setting hardware clock from NIST)

[moseley@hank.org]

Can someone summarize the different ntp packages?  

For example what to run on a server vs. on an internal NAT'ed
workstation.  

Or what is best for a dialup ADSL connection vs. full-time connection. 

Do all packages provied a daemon?


I'm using both chrony and ntp on various machines, and it seems as if 
they both provide ntp network service (via netstat and lsof), but seems 
like I can run this

   nptdate -d <machine running ntp>

but this fails

   ntpdate -d <machine running chronyd>

But I'm not sure why one works and not the other.

Also, what uses the "time" and "daytime" services provided via inetd?
