    I suspected that this is a problem within adjtimex() because strace reported clock
    jump at adjtimex(). But I've just hit this problem with settimeofday() alone.

    ---------- test program 2 start ----------
    #include <sys/timex.h>

    int main(int argc, char *argv[])
    while (1) {
    struct timeval tv;
    struct timezone tz;
    gettimeofday(&tv, &tz);
    settimeofday(&tv, &tz);
    return 0;
    ---------- test program 2 end ----------
