Timer in C++

[sgsawant]

#include<iostream>
#include<time.h>
using namespace std;


int main(void){
	clock_t start, finish;
	start=clock();
	cout<<start<<endl;
	cin.get();
	finish=clock();
	cout<<finish<<endl;
	cin.get();
}

The above code displays outputs similar to:

0

468

It depends on how fast I hit the return key, of course. My question is: what is the unit of time displayed? I am guessing it to be milliseconds.
