Miroslav's references to FLL (frequency-locked loop) were correct.  Please see:

http://www.eecis.udel.edu/~mills/ntp/html/discipline.html

which explains the hybrid PLL/FLL clock discipline algorithm.
Miroslav's suggestion would increase the FLL effect at a lower poll
interval/time constant compared to the default.
