This is done by adding the -x argument to:
     /etc/sysconfig/ntpd

The removal of -x by default is a F8+ change?  I don't recall 
specifically, but its off by default now, and was on before.

Also, you may want to populate /etc/ntp/step-tickers.

With -x in /etc/sysconfig/ntpd, the ntpd startup script will first run 
ntpdate against a clock in /etc/ntp/step-tickers, if any, or from the 
general pool if not.  Then with the system clock in sync, the actual 
ntpd can start and have a better hope of keeping up.

Newer hardware has WAY better clocks than when ntp was written, and thus 
the default removal of the initial ntpdate run.

However, for virtualized machines, or systems with UTC checked on and 
dual booting, you will need it. :)


Good luck!
