My experience so far is that when ntpd is run at startup it keeps the
hardware clock more or less synchronized.  By which I mean, the hardware
appears to be behind the system clock by a little over 1 second, which
should be enough to get the system clock set at a reasonably close value on
the next reboot, until ntpd has a chance to start.
