Time and Date Display

// This program consists of some program snipets that were pieced together by
// #include<DAN.h>. The result of this compilation is a program that displays
// the time and date and refreshes every second.
#include <time.h>   // This includes the time.h header file for getting the 
                    // current time and for waiting
#include <iostream> // This includes the iostream.h header file for input and
                    // output
