    Problem Summary TSD4U.00218 This test may fail on implementations where a time_t can not represent dates in the years 2063 and 2068.
    Problem Text

    XSH5 p. 325 lists the mandated values for getdate_err, including the following:

    8 Invalid input specification. For example, February 31; or a time is specified
    that can not be represented in a time_t (representing the time in seconds since
    00:00:00 UTC, January 1, 1970).

    On the implementation in question, time_t can represent times from
    Dec 13, 1901 8:45:52 UTC to Jan 19, 2038 3:14:07 UTC.

    The test is trying to format dates in 2063 and 2068; the implementation correctly
    reports that time_t cannot represent them.

    Test Output
    TEST PURPOSE #18
    On a call to struct tm *getdate(char *string) the
    field descriptor "%y" shall specify the year without
    century as a decimal number. When a century is not
    otherwise specified, values in the range 69-99 shall
    refer to years in the twentieth century and values in
    the range 00-68 shall refer to years in the
    twenty-first century.

    TEST PURPOSE #21
    On a call to struct tm *getdate(char *string) the
    field descriptor "%D" shall specify the same
    characters as would result from the string
    "%m/%d/%y". Year values in the range 69-99 shall
    refer to years in the twentieth century and values in
    the range 00-68 shall refer to years in the
    twenty-first century.

    Completed null
    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    We recommend this request be refused.

    The specification for %y (and thus %D) requires an implementation to be
    able to represent (at least) dates in the period 1969-2068.

    Review Resolution No Resolution Given
    Review Conclusion
    Systems are not required to support dates beyond 2038, this
    is documented in the specification for touch -t which states:

    "The range of valid times past the Epoch is
    implementation-dependent, but will extend to at least
    the time 0 hours, 0 minutes, 0 seconds, January 1,
    2038, Coordinated Universal Time."

    Review Type SA Review
    Start Date null
    Completed null
    Status Complete
    Review Resolution Test Suite Deficiency (TSD)
    Review Conclusion
    This is an agreed Test Suite Deficiency.
