1. A circuit comprising:
input format-conversion logic configured to convert a received timestamp from an original timestamp format to an intermediate timestamp format;
recursive filter logic coupled to the input format-conversion logic, the recursive filter logic configured to generate a filtered timestamp in the intermediate timestamp format by filtering the received timestamp in the intermediate timestamp format; and
output format-conversion logic coupled to the recursive filter logic, the output format-conversion logic configured to convert the filtered timestamp from the intermediate timestamp format to the original timestamp format and output the filtered timestamp in the original timestamp format.
