    What's the notice about zero sub-second timestamp?

    +

    +In the status command you may now get a notice like: +

    +
    +You have XXXXX files with zero sub-second timestamp.
+Run the 'touch' command to set it to a not zero value.
+
    +

    +It means that a number of your files have a timestamp approximated at the second value, +when instead your filesystem can store a more precise timestamp, with a sub-second precision. +This is not a problem by itself, but it could limit the SnapRAID effectiviness when detecting +moved or copied files. +You have the option to set that subsecond timestamp to a random value using the new 'touch' command. +Note that the second part of the timestamp is not modified. +
