Before somebody else calls me on it, I should point out that NTP
actually uses both:

        "The clock discipline algorithm functions as a nonlinear, hybrid
phase/frequency-lock (NHPFL) feedback loop."


I'm wondering whether the clock discipline might better emphasize
only frequency in such circumstances, as opposed to merely tempering
the PLL.
