ISTR that several postings to the list have touched on this. I don't
have the problem, so I am unsure of the replies. I do seem to recall
that various types of clock settings can be passed on the kernel line in
the grub menu file. One parameter of "pmtr" (?) sticks in my mind. And
there are others. I think a search of the list archives may yield your
best answer.

Although, ntpd is *still* a good idea. I run it just to take care of
those niggling little seconds of drift that all typical PC hardware
clocks can/will experience over time.
