"After him, Mar Rav Hilai bar Mar Rav Chananya, three and a half years" — early 9th century CE.
The Iggeret gives durations for this stretch but itself warns of "disputes such that one cannot rely on them" (1:127), and the durations exceed the interval between the anchored neighbors; no year anchors are assigned rather than invented.
