    Problem Text
    We have previously submitted an error report to X/Open that was accepted.

    We believe that there is a fault in the test suite for T.times test #6. We
    think that a subtraction of one (1) should be done within the 'if' statement
    shown below for test #6. This would then allow for rounding.

    >From the times.c test source:
    -----------------------------
    test5()
    {
    ....

    /* The "-1" is to allow for rounding, in case the system maintains
    the times at higher precision than clock ticks */
    if (buf.tms_cutime - starttime < child_time-1)
    {
    if(!testfail)
    xx_rpt(FAILURE);
    in_rpt("
    When using waitpid() to wait for child process,");
    in_rpt("observed cutime increase: %ld",
    (long)(buf.tms_cutime - starttime));
    in_rpt("observed child utime: %ld", (long) child_time);
    testfail++;
    }
    else
    PATH_TRACE;

    ....
    --------------------------------------------------------------------
    test6(){

    .... if (buf.tms_cstime - starttime < child_time)
    {
    if(!testfail)
    xx_rpt(FAILURE);
    in_rpt("observed cstime increase: %ld",
    (long)(buf.tms_cstime - starttime));
    in_rpt("observed child stime: %ld", (long) child_time);
    testfail++;
    }
    else
    PATH_TRACE;

    Test Output
    /tset/POSIX.os/procenv/times/T.times Test #6
    ============================================
    Test Information:
    observed cstime increase: 14
    observed child stime: 15
    observed cstime increase: 14
    observed child stime: 15
