Miraak was trapped in Apocrypha, time might not work the same way there being a Plane of Oblivion. Queen Alessia made the pact to became Dragonborn on her death bed (and then soul trapped in the Amulet of Kings). We play the game probably for only on a few in-game years at most and there is no aging, but thats game mechanics.
