Is there a reason you are using ntpdate rather than ntpd?  ntpdate is 
supposedly deprecated and ntpd can do what ntpdate does:

     -q      Exit the ntpd just after the first time the clock is set.  This
             behavior mimics that of the ntpdate(8) program, which is to be
             retired.  The -g and -x options can be used with this option.
