Why not degrade the resolution of the clock directly in ntp sources?
Good idea.
In get_systime():
GET_SYSTIME_AS_TIMESPEC(ts);
ts.tv_nsec /= 100;
ts.tv_nsec *= 100;
Ouch!
I'd far prefer a simple mask, getting rid of the bottom N

Linux Kernel 2.4 used 100 Hz and 2.6 increased it to 1000 Hz?
They still read the time to the full CTC
I have some pending changes to improve the way ntpd fuzzes the
insignificant bits of times it reads from the OS clock what that OS
clock ticks slowly enough that it is possible for ntpd to read the
same current time in subsequent gettimeofday()getclock() calls. See
http://bugs.ntp.org/2037.
