PROBLEM TO BE SOLVED: To correct the deviation of the recording time of a value in time sequential data due to discontinuity of the time of a clock.SOLUTION: A time correction system 1 includes: a data acquisition part 2 for acquiring the time sequential data of the value together with information indicating the recording time of each value a determination part 3 for determining whether or not discontinuous data is included in the time sequential data and a correction part 4 for correcting the recording time of the value recorded after the discontinuous data on the basis of a difference between the time indicated by the clock of a measuring device and the time indicated by the clock to be a reference.COPYRIGHT: (C)2013,JPO&INPIT【課題】時計の時刻の不連続による時系列データにおける値の記録時刻のずれを修正する。【解決手段】時刻補正システム1は、値の時系列データを、各値の記録時刻を示す情報とともに取得するデータ取得部2と、時系列データにおいて、不連続データが含まれているか否かを判断する判断部3と、不連続データより後に記録された値の記録時刻を、前記測定装置の時計が指す時刻と、基準となる時計が指す時刻との差に基づいて補正する補正部4とを備える。【選択図】図1
