I'm intrigued by this comment.  The [x]ntp documentation has
traditionally listed two major uses for ntpdate:

1) "ntpdate -b" early in the boot process to get the system clock
   almost right - avoiding xntpd's fairly slow lock-in time and
   ensuring that there's no need for a time step once the system
   is running.

   ntpd may synchronise much faster than xntpd did, but the system
   will still be well into multi-user mode before it realises that
   the clock needs to be stepped by a (possible significant) amount.
   
2) Regular use of ntpdate (eg from cron) to keep the system clock
   fairly close to real time without the overheads of permanently
   running nptd.

   Whilst this is less of an issue for modern systems, people may
   still have reasons for not wanting to run ntpd.

How will these functions be handled in the absence of ntpdate?

Peter
