A couple of hundreds of millions of years either way do not matter, since at least that much time was required for the interpassage. At about that same time-within the same plus or minus ten percent margin of error, it is believed practically all of the suns of both those galaxies became possessed of planets.There is much evidence to support the belief that it was not merely a coincidence that so many planets came into being at about the same time as the galactic inter-passage.
