    Problem Summary TSD4U.00037 The getdate() specification defines a %R field descriptor but the LC_TIME locale definition (XBD section 5.3.5) does not specify a corresponding keyword. For VSU5 this applies in UNIX95 mode only.
    Problem Text
    This test assumes that the hour and minute fields will be separated by
    the at sign, '@'. This is not the case. A colon, ':', is used under
    default circumstances, such as the %R under test.

    Unfortunately no format for %R is specified in the locale
    definition grammar. This is a hole in the specifications for
    locales.
    Test Output

    Review Response
    The getdate() specification defines a %R field descriptor but the
    LC_TIME locale definition (XBD section 5.3.5) does not specify a
    corresponding keyword.

    The getdate() specification defines %R as "The locale's
    appropriate representation of time", and %X as "locale's
    appropriate time representation". This creates an appearence
    that %R and %X are to be interpreted identically. But we believe
    existing practice is to interpret %X as per the locale's t_fmt
    keyword but to always interpret %R as %H:%M no matter what the
    locale.

    Therefore, we recommend that the %R definition in the getdate()
    specification be changed from

    %R The locale's appropriate representation of time. In the POSIX
    locale, this is equivalent to %H:%M

    to

    %R time as %H:%M

    A permanent interpretation is recommended.


    Please note: We noticed the spec also fails to specify a
    keyword which corresponds to %r. We also recommend that
    the %r definition in getdate() be changed from

    %r The locale's appropriate representation of
    time in AM and PM notation. In the POSIX
    locale, this is equivalent to %I:%M:%S %p

    to

    %r time as %I:%M:%S %p

    And that the %r definition in the date utility be changed from

    %r 12-hour clock time [01-12] using the
    AM/PM notation; in the POSIX locale,
    this will be equivalent to "%I:%M:%S %p".

    to

    %r 12-hour clock time [01-12] using the
    AM/PM notation; this will be equivalent
    to "%I:%M:%S %p".

    Review Conclusion
    The review has indicated that the suggested specification changes will be
    input to the normal specification development process and given due
    consideration in the formulation of the next version of the specification.
    However in this case it is recommended that a test suite deficiency be
    granted rather than a Permanent Interpretation.

    Review Conclusion
    This is an agreed Test Suite Deficiency. For VSU5 this applies in UNIX95
    mode only.
