I can tell you that during the main story line during the big ceremony thing with the leaders of the grand companies making their speeches, that the Flame General Raubahn Aldynn says that we are in the fifth year of the Umbral Age. Unfortunately while cleaning out my FRAPs folder I deleted the screenshot. But I know with 100% certainty (unless SE changes the dialogue come phase 4) that the General says fifth year of the Umbral Era.
