int main (int argc, char *argv[])
    {
    time_t currentTime;
    struct tm *targetTime;
 
    // Get current time 
    time (&currentTime);
    //Convert time_t to tm as local time 
    targetTime = localtime (&currentTime);
 
    //set alarm time at 7:30 of tomorrow
    targetTime->tm_mday = targetTime->tm_mday + 1;
    targetTime->tm_hour = 7;
    targetTime->tm_min = 30;
 
    alarm_event_t  event;
    // initializing  event object
    memset (&event, 0, sizeof (alarm_event_t));
 
    // set event's alarm from targetTime
    event.alarm_time = mktime (targetTime);
 
    //add alarm event
    cookie_t coo = alarm_event_add (&event);
