Claim 14:
15. The method of claim 14, wherein the adjusting the determined times of the group of transitions comprises, for each transition of the group of transitions, performing one selected from the group consisting of:
based on the threshold voltage being a positive voltage, adjusting the determined time of the transition to add the negative-going time offset and subtract the second 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 threshold voltage being a negative voltage, adjusting the determined time of the transition to subtract the negative-going time offset and the second time offset to produce the time of the negative-going zero-crossing of the input AC waveform indicated by that transition.
