This is something that is done by the operating system (e.g. every 11 
minutes in Linux, or by cron jobs in some other systems), not by ntpd. 
Some people object to this behaviour in Linux because it prevents the 
effective use of hwtime to correct RTC frequency.

As such, the identity of the OS is important in answering the question.
