PS: I'd like to clarify I am not thinking about something like the
tinker directive. Rather, I am thinking about something like the
following (when said option is set):
- upstream signals a leap second insertion/deletion
- after 23:59:59, ntpd consciously does NOT insert the leap second and
suspends step adjustments for a convenient amount of time (T seconds)
- for T seconds, ntpd tries to slow down / speed up the clock to make up
for the leap second
- if, after T seconds, the normal behaviour is restored. If the offset
is still too big, a step change will be forced.
