Very Computer

i would like to set the correct time on my linux box when the connection to
the internet via dial on demand is established (using /etc/ip-up)

i read about the netdate tool and would like to know which timeservers I
could use and which experiences you made

thanks

You want ntpdate which can update your system clock from time servers.  
If you installed xntp then there should be docs on your system that link
to the list of time servers.  You should use stratum 2 servers.  Pick some
close to home (mine would be too far away).

If you do put it in a ppp script (or /etc/ppp/ip-up.local) you probably
want to do something like this:

sleep 1
/usr/sbin/ntpdate -bs some.time.server
/usr/sbin/setclock

However, non-RedHat distros may have hdwclock or something else to set the
CMOS clock.

Here I was, minding my own business, and wouldn't you know it?

        Guess you could easily add the extra command to the ip-up script.
