Sorry, I can’t see what you mean in the generated code.
The "unknown PPS" synchronization method waits for a 1PPS pulse to
arrive, and then commands the hardware to set the
time-of-day clock to 0 at the next PPS.
Because you have two entirely different source blocks (necessitated by
the fact that you have two different types of hardware),
there will necessarily be a time-of-day disagreement between the
devices because first one block does this synchronization
(waiting for things to happen), and THEN the other block does the
same. Once the first block is done its synchronization,
its time-of-day clock marches forward, and THEN the second block does
the same thing. The two time-of-day clocks
don't match.
