It's not only the speed. All of the timestamps of the files are even numbers, which is indicative of a FAT file system. > "The directory entry for the FAT file system only has a 5-bit field for storing the number of seconds in the time. This limits the number stored in the field to the range 0-31, which is multiplied by two to obtain the number of seconds." The timestamps appear to have been copied to a FAT filesystem (common for USB devices) on May 25, 2016. https://turcopolier.typepad.com/sic_semper_tyrannis/2019/04/test-it-yourself-the-2-second-rounding-fact-pattern-in-the-dnc-emails-by-william-binney-and-larry-jo.html https://turcopolier.typepad.com/sic_semper_tyrannis/2019/04/...
