    #include<cstdlib>

    much like my ex, this is the quick, cheap, and dirty method:

    date and time are basic dos commands if that is what you are looking for

    Code:
    system("date");   //you'll have to make a provision for
                      //when the date command prompts you for a 
                      //new date

    I think I need more help...here's what I want to do: I need to create a file on the first second of every new day. I know my program will have to be running all the time and that's not a problem, but I have no idea how to do what I want. Any suggestions?

    Use the task scheduler provided by your platform. For Windows, this can be found under Start Menu->Programs->Accessories->System Tools->Scheduled Tasks.

    There is a really easy way of doing it, but it isn't the best. On the other hand, there is another way with Win32, but I'm not too sure bout that, so I'll post the other other way for now
    The first way is to do something like this...
    Code:
    #include <fstream>
    
    while(1)
    {
    Sleep( 86400000 ); // This is the millisecond equivilant of 24 hours
      ofstream a_file ( "File.txt" );
      std::a_file << "This will be in the file 'File.txt'.";
      a_file.close();
    }
    This method works, but you need to start it off at midnight for it to work the way it should. Also, include the windows header file to use the Sleep function.

    Code:
    #include <ctime>
    
    char *str;
    time_t cur_time = time(NULL);
    //cur_time should be your calaender time (in seconds) from:
    strftime(str, 128, "%A %d %B %H %Y", 0);
    printf("%s", str);
