No, that's her first experience in the columns, where she saw the traditional Aiel history, and the ??? marker indicates I'm highly uncertain about the precision of that timing. Her second experience began the same day she finished the first; I marked it as between 811 and 821, since there's an interlude where she ends one vision and sees the sun shining, indicating that Rand's epiphany has happened. Since we have that marker, I'm more certain of the timing for the second experience.
