    Problem Text
    Our strptime() function converts the input string "6 pm" using the format
    string "%H %p" as follows:

    1. The %H conversion specification in the format string causes "6" to be
    scanned from the input string, and the value 6 is stored into tm_hour.
    2. The directive consisting of the space character in the format string
    causes the space character to be scanned from the input string.
    3. The %p conversion specification in the format string causes "pm" to
    be scanned from the input string, and the value 12 is added to
    tm_hour, resulting in 18.

    XPG4 does not provide enough details to indicate whether tm_hour should
    be 6 or 18. We believe 18 makes more sense. Unless evidence is provided
    to the contrary, XPG4 allows our implementation to behave as described
    above. For this reason, a permanent waiver is requested.
    Test Output
    /tset/XPG4.os/time/strptime/T.strptime 5 Failed

    Test Description:
    If strptime() is supported:
    When format is a string containing the following field descriptors
    :
    a. a or A abbreviated or full weekday name - eg. Sun to Sat or
    Sunday to Saturday
    b. b, B or h abbreviated or full month name - eg. Jan to Dec or
    January to December
    c. c appropriate date and time as specified in the D_T_FMT string
    d. p AM/PM string as specified in the AM_STR/PM_STR
    e. x appropriate date as specified in the D_FMT string
    f. X appropriate time as specified in the T_FMT string
    then a call to strptime() reads characters from string and, in the
    case that these characters match the format of the directive,
    translates these characters into the appropriate member of the tm
    structure.
    Otherwise:
    A call to strptime() returns NULL and sets errno to ENOSYS.

    Test Strategy:
    PARENT process will
    CREATE child process using cppair()
    CHILD process will
    SET the locale for LC_TIME to VSX4L1
    FOR each day format
    FOR each full weekday name
    GET the relevant string using pslanginfo()
    INITIALISE the tm structures
    VERIFY that strptime() performs as expected
    FOR each abbreviated weekday name
    GET the relevant string using pslanginfo()
    INITIALISE the tm structures
    VERIFY that strptime() performs as expected
    FOR each month format
    FOR each full month name
    GET the relevant string using pslanginfo()
    INITIALISE the tm structures
    VERIFY that strptime() performs as expected
    FOR each abbreviated month name
    GET the relevant string using pslanginfo()
    INITIALISE the tm structures
    VERIFY that strptime() performs as expected
    FOR format strings D_T_FMT, AM_STR, D_FMT, and T_FMT:
    INITIALISE the tm structures
    VERIFY that strptime() performs as expected
    REPEAT everything contained above in this test for the locale
    VSX4L2

    Test Information:
    PM string as specified in AM_STR
    strptime("6\040pm", "%H %p", &testbuf) failed.
    Current language is VSX4L2
    tm_hour = 18, expected 6
