Abstract
A time stamp correction apparatus that corrects a deviation between time stamps of pieces of data acquired by physically connected NW apparatuses by correcting a deviation in a time stamp between pieces of traffic data is provided. The time stamp correction apparatus includes a waveform similarity computation unit that determines an IF pair based on a similarity between waveforms of time-series data of traffic observed in respective interfaces of the NW apparatuses, and a time stamp correction unit that generates correction information for correcting a deviation between the time stamps of the pieces of data based on feature points of time-series data of traffic observed in the IF pair.
