    Well, in addition to the objections raised by John, your suggested
    implementation is also shortsighted. The field timex.constant is
    copied into time_constant in some code paths. Obviously, this would be
    a bad thing when timex.constant==-huge.

    So, you need to clarify the interaction between ADJ_OFFSET,
    ADJ_TIMECONST, ADJ_TAI, timex.constant, time_constant, and MAXTC.

    If you would fully implement your idea, I expect it would become
    obvious that it a bit of a hack, both in the kernel code and in the
    user space interface. But, if you disagree, please just post a patch
    with the complete implementation...
