Wouldn't that be forward in time? "Ragnarok" is the Norse version of the Apocalypse (also, in actual Norse mythology, it comes around in cycles if I remember correctly, with the world just resetting to the beginning and going again; although that would mean Thor could theoretically go back to stop the last Ragnarok, I can't see why he would, seeing as that would negate his own timeline).
