Claim 6:
7. The method of claim 6, wherein:
the adjusting the determined times of the first group of transitions comprises, for each transition of the first group of transitions, performing one selected from the group consisting of:
based on the first threshold voltage being a positive voltage, adjusting the determined time of the transition by subtracting an amount of time determined as a function of the positive-going time offset to produce the time of the positive-going zero-crossing of the input AC waveform indicated by that transition; and
based on the first threshold voltage being a negative voltage, adjusting the determined time of the transition by adding an amount of time determined as a function of the positive-going time offset to produce the time of the positive-going zero-crossing of the input AC waveform indicated by that transition; and

the adjusting the determined times of the second group of transitions comprises, for each transition of the second group of transitions, performing one selected from the group consisting of:
based on the second threshold voltage being a positive voltage, adjusting the determined time of the transition by adding an amount of time determined as a function of the negative-going time offset to produce the time of the negative-going zero-crossing of the input AC waveform indicated by that transition; and
based on the second threshold voltage being a negative voltage, adjusting the determined time of the transition by subtracting an amount of time determined as a function of the negative-going time offset to produce the time of the negative-going zero-crossing of the input AC waveform indicated by that transition.
