De oplossing:
bestand ntpdate
#! /bin/sh
test -f /usr/sbin/ntpdate || exit 0
# Instructions:
# update the line below that calls ntpdate to include a list of IP
# addresses of NTP servers you wish to query to learn the time to set
# the local clock to. Then, comment out the next two lines that contain
# the echo and the exit.
#echo "You must customize /etc/init.d/ntpdate before ntpdate can be run."
#exit 0
case "$1" in
start)
echo -n "Running ntpdate to synchronize clock"
/usr/sbin/ntpdate -b -s 158.43.128.66 # space-delimited IP address list goes here!
echo "."
;;
stop|restart|force-reload)
;;

echo "Usage: /etc/init.d/ntpdate {start|stop|restart|force-reload}"
exit 1
esac
exit 0
bestand ntp.conf
bijvoegen
server npt0.nl.net
server ntp0.nl.net
Dan in de shell typen:
ntpdate ntp0.nl.net
Nou geeft ie iets aan van adjust time server (ipadress) offset
