[time-nuts] Can (will) a M12+T generate a negative sawtooth message ?

The ref output is the minimal delay through the chip covering the input and
output pad buffers. It will vary slightly with temperature and voltage.
There are no negative delays in that sort of chip. It's just a bunch of
gates/buffers with a carefully calibrated delay. (For a negative delay, you
would need something like a PLL.)
If the delay from the M12+T might be negative, set the antenna cable delay to
be a bit short and add on a constant in software.
These are my opinions. I hate spam.
