632 * it is not statistic jitter, the source will be detected as
633 * falseticker sooner or later. Enforcing a minimal jitter value
634 * avoids a too low estimation while still detecting higher jitter.
637 * clock dispersion, not the clock jitter, despite being called
638 * jitter. To see the modified values, check the NTP clock variable
639 * "filtdisp", not "jitter".
