linux-oznb:~ # ntpdate ntp1.ptb.de
       !!!!!!!!!!!!!!  WARNING !!!!!!!!!!!!!!!!!!

The ntpdate program is deprecated and should not be used any more.  To
quote the upstream ntp developers:

  "The functionality ntpdate offered is now provided by the ntpd daemon
  itself.  If you call ntpd with the command line option -q it will
  retrieve the current time and set it accordingly."

Please check the Network Time Protocol (NTP) daemon man page and
  http://support.ntp.org/bin/view/Dev/DeprecatingNtpdate
for further information.

You can replace the ntpdate call with "rcntp ntptimeset" to achieve an
inital poll of the servers specified in /etc/ntp.conf.

The program /usr/sbin/sntp offers comparable functionality to ntpdate.
Specifically
  sntp -P no -r pool.ntp.org
is equivalent to
  ntpdate pool.ntp.org

For further details please refer to the man page of sntp.
