    Problem Text

    We think that the following "-atime" option for "find" will
    be incorrect in assertion #60.

    find libDUMMY.a -atime -1 -print > $CT_STDOUT 2> $CT_STDERR


    The "-atime" option is described in CAE specification as follows:

    True if the file access time subtracted from
    the "find" command activation time is n-1 to n
    multiples of 24 hours. For example, -atime 3
    is true if the file was accessed any time in
    the period from 72 to 48 hours ago.

    And, "n" of "-atime n" is described:

    The primary will evaluate as true if the file acess
    time subtract from the initialisation time is n-1 to
    n multiples of 24 hours.

    So, "-atime 1" mean "files accessed during the last 24 hours",
    and "-atime -1" mean "files will be accessed during this 24
    hours". It is because "-n" means "less than n".

    current
    +----------+----------+----------+----------+
    n-1 n
    ------ -n -----><--- n ----><--- +n ------

    Now, "libDUMMY.a" is accessed by fort77 before "find",
    so "find" never return anything.

    We think that "find libDUMMY.a -atime 1 -print" will be
    correct. We believe there is an error in test #60.

    Review Response
    We recommend this request be refused. We believe the test is correct.

    The find OPERANDS section states that -n means, "less than n," and in
    this content, less than n 24-hour time periods (24*n hours) ago. The
    EXAMPLES section on page 349 describes the meaning of this related to
    atime:

    7. The descriptions of -atime, -ctime and -mtime
    use the terminology n ``24-hour periods''.
    For example, a file accessed at 23:59 will be
    selected by:

    find . -atime -1 -print

    at 00:01 the next day (less than 24 hours
    later, not more than one day ago); the
    midnight boundary between days has no effect
    on the 24-hour calculation.

    The meaning of n and -n are different. Using n refers to a particular
    range of time, n-1 to n, in the past. Using -n refers to a block of time less than a n in the past.
