Dirshu Chadasha 167:7, M.B. 34, note 22 cites various places where M.B. gives conflicting amounts of time. In some places, M.B. writes the time is 3 words of "Shalom Alecha Rebbi," and in other places M.B. writes the time is 4 words of "Shalom Alecha Rebbi U'Mori." Dirshu concludes the main halacha is the three words time as per most achronim and the implication from M.B.</ref> which is about 2 seconds. | |||
