Like so?
tw=time waster

EDIT: WHY WON'T THIS SoB WORK?!?
Code:
#include <conio.h>
#include <fstream.h>
#include <iomanip.h>
#include <iostream.h>

//This is the start of my program.
int main()
{
 //prints to the text file.
 ofstream outfile ("500.txt");

 //Declaring my variables.
 int hours;
 int minutes;
 int seconds;
 int tw=1000;
 cout << "This program, will function as a countdown 'clock'. Please enter your value for hours, then your value for minutes, followed by your value for seconds.\n";
 outfile << "This program, will function as a countdown 'clock'. Please enter the number you would like to countdown from.";
 cin >> hours;
 cout << "hours";
 cin >> minutes;
 cout << "minutes";
 cin >> seconds;
 cout << "seconds";
 while (hours >= 0)
   {
    while (minutes >= 0)
       {
        while (seconds > 0)
           {
            while (tw>0)
               {
                tw--;

                if (tw==1)
                 seconds++;
               }
            seconds = seconds - 1;
           }
        seconds=60;
        minutes=minutes - 1;
       }
    minutes = 59;
    hours = hours -1;
   }
cout << "Time's up!";

 //That stuff at the end.
 getch();
 return 0;
}
