I try to integrate https://github.com/NordicPlayground/nrf5-calendar-example into Keil project. But the following error messages shown when accessing NRF_CLOCK.

Thanks for your great support! Time is correct after changing nrf_cal_set_time() as follows.

void nrf_cal_set_time(uint32_t year, uint32_t month, uint32_t day, uint32_t hour, uint32_t minute, uint32_t second) {
    NRF_LOG_DEBUG("nrf_cal_set_time(%u, %u, %u, %u, %u, %u) e\n", year, month, day, hour, minute, second);
    static time_t uncal_difftime, difftime, newtime;
    time_struct.tm_year = year - 1900;
    time_struct.tm_mon  = month - 1;
    time_struct.tm_mday = day;
    time_struct.tm_hour = hour;
    time_struct.tm_min  = minute;
    time_struct.tm_sec  = second;   
    newtime = mktime(&time_struct);
  
    CAL_RTC->TASKS_CLEAR = 1;  
    
    // Calculate the calibration offset
    if (m_last_calibrate_time != 0) {
        difftime = newtime - m_last_calibrate_time;
        uncal_difftime = m_time - m_last_calibrate_time;
        m_calibrate_factor = (float)difftime / (float)uncal_difftime;
    }
    
    // Assign the new time to the local time variables
    m_time = m_last_calibrate_time = newtime;
    //_nrf_cal_print_time_t(newtime);
    gCalTimeSet = true;
    NRF_LOG_DEBUG("nrf_cal_set_time(%u, %u, %u, %u, %u, %u) x\n", year, month, day, hour, minute, second);
