Just a note about possible spurious pulses with the TICC. The input circuit is
a 3.3v logic gate that's 5v-safe. Some PPS signals have much greater peak
amplitude than that (e.g., the HP atomic clocks).
Experience has shown that these pulses don't know have enough energy to damage
the input,

I have a hack that grabs everything and writes each line and a time stamp to a
file per day.

I have a couple of GPS receivers I'm experimenting with that I've been
using a TICC to gather timestamps of the 1PPS output to ascertain
their relative quality.
In the process of doing this, I've discovered that some of the 1PPS
outputs are not as stable as I'd like them to be. For instance, the
