Instead of writing a cron job to use ntpdate, IMHO you should
configure ntp and bypass ctss completely. Configure it once on all
your hosts and voilà! all your troubles are over (well, one of them at
least :) Plus ntp is very easy to setup. If you need help on that or a
reliable time source, check http://www.pool.ntp.org/en/
HTH,
