The time difference method is used to calculate the average frequency relative bias according to the current JJG 292-2009 Verifi-cation Regulation of Rubidium Frequency Standards. But this method will make mistakes in two special cases. For solving the problem, the spe-cial causes are analyzed, the corrected formulae are deduced for different cases and the necessity of the discussion is stated by means of the nu-merical examples.
