I have created my own /etc/ntp-my.conf and changed startup script / 
System/Library/StartupItems/NetworkTime/NetworkTime to use this file.  
BTW Apple uses /var/run/ntp.drift file to store drift value. This is  
stupid because contents of /var/run is lost after reboot. I've  
changed this to /etc/ntp.drift.

I am mostly disappointed by Mac. (Almost) perfect visual design, lack  
of engineering. Misunderstanding of NTP is very clear but not the  
only example of this.

Thank you for this advice! Looks like this is the best possible way.

Could all this information be added to FAQ?..
