It's a bad idea in the general case.  If you have scheduled jobs, ntpdate may 
jump the clock enough to miss the trigger or run them twice, where ntpd always 
tries to move the clock fractional seconds at a time so as not to let that 
happen.   Plus, ntpdate does no sanity check at all - if the clock source is 
badly off, the client will follow blindly even if it goes to the wrong century.
