The directive takes two arguments, the maximum frequency offset of the smoothed time to the tracked NTP time (in ppm) and the maximum rate at which the -frequency offset is allowed to change (in ppm per second). +frequency offset is allowed to change (in ppm per second). The smoothing +process is activated when 1/10000 of the estimated skew of the local clock +falls below the maximum rate of frequency change.
