It'll still be a problem for code that relies on time being 64-bit int of nanoseconds. How do you change the internal representation here without also breaking the API contract for application code?

The kernel does not have an API that exposes that representation to user code; system calls operate on timespec structs

  struct timespec {
        time_t   tv_sec;        /* seconds */
        long     tv_nsec;       /* nanoseconds */
  };
