            ($atime, $mtime) = (stat($timestamp))[8,9];
            utime $atime, $mtime, @ARGV;

    at the expected level of precision. For example, the FAT and HPFS
    filesystem are unable to create dates on files with a finer granularity
    than two seconds. This is a limitation of the filesystems, not of
