    I believe there are minor mistakes in help topic "timestamps.htm". I use the
    "date range" notation below to combine date and time of day.

    1/ I thought that age=0 represents 1601-01-01@00:00:00 (Gregorian calendar),
    instead of 1601-01-01@00:00:01, which was 1s later.

    2/ The reference epoch, i.e., the earliest event timestamp for Unix and
    Linux is 1970-01-01@00:00:00, not 1901-12-14@00:00:00, as can be seen on
    http://www.unix.org/single_unix_specification/ in par. 3.149, "Epoch".

    3/ The latest event timestamp in Unix/Linux is 2038-01-19@03:14:07, as
    calculated by the command
    echo %@agedate[%@eval[%@makeage[1970.1.1,0:0:0]+(2**31-1)*10**7]]

    4/ UTC should be added in the latest timestamp column for the NTFS and Unix
    file system epochs.

    The formatting of the latest timestamp ought to be ISO, including the
    leading zeros.

    You can easily change the system date in Linux to 1901.

    But it's not really important, as I've deleted the Linux row as irrelevant.

    The table in V7, v8 and V9 has the values I entered. Only V10 is different
    from what I did.
