#include   
#include   
  
int main()  
{  
    time_t nowtime = time(NULL);  
    tm *now = localtime(&nowtime);  
    printf("now: %04d-%02d-%02d %02d:%02d:%02d\nunix time: %ld\n",   
        now->





tm_year+1900, now->tm_mon+1, now->tm_mday,   
        now->tm_hour, now->tm_min, now->tm_sec, (long)nowtime);  
    return 0;  
}
