I don't exactly get what you'r needs are. If you mean a C/C++ program to read the system time, I can do it.

Code:

#include <iostream>
#include <ctime>
using namespace std;

int main() {
   time_t t = time(0);
   cout << "The time is : " << ctime(t) << endl;

   return 0;
}

Type 'man ctime' in your terminal to get details about the various time structures.

No.
I mean the hardware RTC.

why, when Paul Gortmaker has done already, look in /usr/src/linux/Documentation/rtc.txt generally if you want to talk to a device driver then there will be some sort of documentation in /usr/src/linux/Documentation please at least look here before you post
