Time client setup

1. Immediate synchronization with e.g.:

   /usr/sbin/ntpdate de.pool.ntp.org
   

2. Adapt /etc/ntp.conf as suggested in that file:

   server timeserver1.gsi.de # GSI only !
   server de.pool.ntp.org
   #
   driftfile /var/lib/ntp/drift
   

   The dhclient (/sbin/dhclient-script) seems to change the server entries, why this???
3. Start the daemon once:

   /sbin/service ntpd start
   

   and prepare it for automatic startup:

   /sbin/chkconfig ntpd on
