I use adjtimex for that. Keeps the clock within miliseconds.

#Now set the system clock from some Internet Time servers
# Penn St. Univ NC Deleware MIT
netdate 128.118.46.3 192.101.21.1 128.175.60.175 18.72.0.3

Yes thats what the manual says but I can get it to work! I have TZ=EST-5
in /etc/profile and the hwclock gets set 5 hours off? Thats been bugging me for 2
weeks now. date and clock are the same but hwclock --show is 5 hours
off. I am still working on that. I am trying to set the date to EST
and the CMOS to GMT.
