A reminder that at 2am PDT, the clocks went back one hour to 1am PST. This means the hourly autoburt wrote out two "1am" sets of data, the second one overwriting the first. This can be seen if we look at a GPS time channel in one of the snap files. There gap between the midnight entry and the "1am" entry is 7198 seconds, or 1.999 hours.
Also remember local time is now UTC - 8hr
