this answer  Uninstall ntpd if it is installed. You will still
have ntpdate installed. (It is difficult to remove.) Prevent it
from executing by adding exit 0 to /etc/default/ntpdate.

it's not in Ubuntu/Debian. It's RedHat (and other rpm based
distros) specific. –  Mr Shunz Mar 9 '11 at 15:41  Your Answer
