Samsung Galaxy Watch：mdm_set_automatic_time() 返回状态 -13 且未设置时间

Question

我有：

设备：Samsung Galaxy Watch Active (SM-R500)；
Tizen 版本 (API): 4.0;
适用于可穿戴设备的 Knox Tizen SDK 版本：2.4；

在 Knox 合作伙伴门户网站上，我找到了活动 KPE 标准密钥，然后将其实施到我的代码中。
我有权使用 ppm_check_permission 函数设置时间函数 (http://developer.samsung.com/tizen/privilege/mdm.datetime)：

...

const char *privileges[] =
{
    "http://tizen.org/privilege/mediastorage",
    "http://tizen.org/privilege/location",
    "http://tizen.org/privilege/healthinfo",
    "http://developer.samsung.com/tizen/privilege/mdm.admin",
    "http://developer.samsung.com/tizen/privilege/mdm.datetime",
    "http://developer.samsung.com/tizen/privilege/mdm.location",
};

...

static void _ppm_request_response_cb(ppm_call_cause_e cause, ppm_request_result_e result, const char *privilege, void *user_data)
{
    if (cause == PRIVACY_PRIVILEGE_MANAGER_CALL_CAUSE_ERROR)
    {
        LOG_PRINT(DLOG_DEBUG, "Error request response!");
        /* Log and handle errors */
        return;
    }

    switch (result)
    {
    case PRIVACY_PRIVILEGE_MANAGER_REQUEST_RESULT_ALLOW_FOREVER:
        /* Update UI and start accessing protected functionality */
        LOG_PRINT(DLOG_DEBUG, "PPM request result: allow forever");
        break;
    case PRIVACY_PRIVILEGE_MANAGER_REQUEST_RESULT_DENY_FOREVER:
        /* Show a message and terminate the application */
        LOG_PRINT(DLOG_DEBUG, "PPM request result: deny forever");
        ui_app_exit();
        break;
    case PRIVACY_PRIVILEGE_MANAGER_REQUEST_RESULT_DENY_ONCE:
        /* Show a message with explanation */
        LOG_PRINT(DLOG_DEBUG, "PPM request result: deny once");
        ui_app_exit();
        break;
    }
}

...

static bool _create_cb(void *data)
{
    int i = 0;
    int ret = PRIVACY_PRIVILEGE_MANAGER_ERROR_NONE;

    int size = sizeof(privileges) / sizeof(char *);

    setlocale(LC_ALL, "en_US.UTF-8");

    for (i = 0; i < size; i++)
    {

                break;
            case PRIVACY_PRIVILEGE_MANAGER_CHECK_RESULT_DENY:
                LOG_PRINT(DLOG_DEBUG, "PPM error request response: deny");
                ui_app_exit();
                break;

    }

    me_init();

    gui_create_base();

    c_set_state(ST_WIZARD_STEP1);

    elm_run();
    return true;
}

...

调用功能的过程：

...

me_init();
me_disable_automatic_time();
me_set_date_time(2020, 3, 31, 16, 54, 1);

...

我的问题:
对于函数 mdm_set_automatic_time() 使用我的商业密钥返回状态 -13，但同时状态为 mdm_activate_knox_license() 是 MDM_RESULT_SUCCESS.
但它工作正常，并且错误不会在多个设备上重复出现，它是 42 台设备中的 2-3 台。对于这些设备，已使用控制台 Knox Configure 上传应用程序。

我会做错什么样的动作？

问题出在三星服务器端计算hash的时候。问题解决了。
