Rule 713.1
Official source text from the 16 January 2016 Rules release
Three cards (Time Stop, Sundial of the Infinite, and Day’s Undoing) end the turn. When an effect ends the turn, follow these steps in order, as they differ from the normal process for resolving spells and abilities (see rule 608, “Resolving Spells and Abilities”).
