memory leaks

Looks like you aren't taking advantage of c++ at all. this looks like c with classes approach with boost?

#include <windows.h>

#include <ctime>
#include <string>
#include <iostream>
#include <boost/circular_buffer.hpp>
#include <boost/foreach.hpp>

using namespace std;
using namespace boost;

string getDateTime()
{
	time_t rawtime = time(NULL);
	tm* timeinfo = gmtime(&rawtime);
	char szTime[30];
	strftime(szTime, 30, "%a, %d %b %Y %X GMT", timeinfo);
	return szTime;
}
 
struct Buffer 
{
	string payload;
	int user;
	Buffer() : payload(), user() { }
	Buffer( const string& payload, int user ) : payload(payload), user(user) { }
};
 
int main()
{
	const int numbuff = 3;
	circular_buffer<Buffer> cb(numbuff);
 
	// Insert elements
	cout << "Push elements:" << endl;
 
	for( int i = 0; i < 5; i++ )
	{
		cb.push_back( Buffer( getDateTime(), i ) );
		Sleep(1000);
	}
 
	// Show elements:
	cout << "Show elements:" << endl;
 
	BOOST_FOREACH( Buffer Record, cb )
	cout << Record.payload << endl;
 
	system("pause");
	return 0;
}

This is more c++ than the c approach , but understanding how and why to use string, constructors, containers and etc will take time. If this isn't what you require, just state what is wrong with the above code.
