These data are presented for the Sony AS30V action camera. Date/time stamps are accurate in the file system only to the nearest 2 second period, so the ultimate accuracy of the starting or ending time tage can be said to be +/- 1 second. The GPS date/time accuracy is kind of unknown, since the processing delays in the GPS data logger in the camera are unknown. It would be likely that these delays are much, much less than 1 second. In this analysis, we assume that the time tagging represents an error so much greater the GPS time tag, the GPS time tag is assumed to be precise.
