Ok. The ntpd example in the document should be probably updated too.

Please note that the performance of chronyd on non-Linux systems may
not be adequate for the precision of the PPS source. Its system driver
will use only the old adjtime() system call to discipline the clock,
there is no correction of the frequency offset and the resolution is
limited to microsecond.
