If the signal is NOT inverted then the raising edge will be within
nanoseconds of the UTC seconds "tick".    The inverted PPS will have the
edge delayed somewhat.   It is not even clear if the length of the delay is
constant.

If using the PPS for timing and the PPS is inverted you will have to
measure the delay length an account for in the config file.
