It most recently happened to me for November 3rd, I had YVR-SFO-LAX (UA ticket) booked and the YVR-SFO was AC metal codeshared by UA. I called AC to select my seat two weeks before the flight and the agent said "do you realize you have negative 15 minutes connecting time?". Everything still looked OK on UA.com but there had been a schedule change to the AC flight months earlier that was never picked up by United. But it's far from the first time I have seen major discrepancies between the published times of the same flights between UA and AC on this route.
