Bruce R. McConkie identifies Adam with both the archangel Michael and the Ancient of Days; Adam will "sit in formal judgment" of his posterity.

Ancient of Days
See ADAM, ADAM-GOD THEORY, ADAM-ONDI-AHMAN, BIRTHRIGHT, MICHAEL THE ARCHANGEL, PATRIARCHAL ORDER. Having particular reference to his position as the patriarchal head of the human family — the first man, "the first and oldest of all, the great, grand progenitor" — Adam is known as the Ancient of Days. (D. & C. 27:11; Teachings, pp. 157-159, 167-169.) In this capacity he will yet sit in formal judgment upon "ten thousand times ten thousand" of his posterity, and before him at Adam-ondi-Ahman will be brought the Son of Man to receive "dominion, and glory, and a kingdom, that all people, nations, and languages, should serve him." (Dan. 7:9-14.)
