This is what the -u parameter is for. See the man page. But yes -
running ntpdate when you are also running ntpd is silly. 

ntpdate is useful in system startup to force the clock right before ntpd
starts in case your bios clock is wrong. I use it in kickstart and then
set the bios clock right after.
