// Test case to demonstrate that operator<< of
// boost::posix_time::ptime doesn't take a set ios::failbit into
// account correctly but instead prints itself everytime.

// Compile and run as follows:
//    g++ ptime-operator.cpp -o ptime-operator
//    ./ptime-operator

#include <ios>
#include <boost/date_time/posix_time/posix_time.hpp>
#include <boost/version.hpp>
using namespace std;

int main(int /*argc*/, char** /*argv*/)
{
	boost::posix_time::ptime p = boost::posix_time::microsec_clock::local_time();

	// The following line should appear
	cout << "Should appear: Text. And Date: " << p  << " Boost v" << int(BOOST_VERSION) << endl;

	cout.clear (std::ios::failbit);	// set ios::failbit -> no more output

	// The following line should *not* appear, BUT the time is printed
	// anyway! (That's the bug.)
	cout << "Should not appear: Text. And Date: " << p << endl;

	cout.clear (); // remove ios::failbit -> resume output

	// The following line should appear again
	cout << "\nThis line should appear (but no single date above): Text. And Date: " << p << std::endl;
