change timer steering
...
What we desire is long-term stability at the expense of short-term
accuracy. Therefore, don't steer the timer based on local measurements
(which has a very low precision, counts per wwvb second is 1/1000
or 1000ppm), but instead base it on long-term measurements (e.g., counts
per wwvb day or so, 12ppb)
The resolution of the divisor is 1 clock per 32.678 seconds, or 6ppb when
the clock is nominally 5MHz.

this, or something very close to it, did actually set the time once
but since then it stopped even synching to the wwvb pps.
