I am saving and restoring thousand ptimes and integers. If I am 
saving/restoring only ptimes - everything works. If I add integers to it - it 
breaks. Code to reproduce the problem is shown below. I will appreciate any 
help in solving the problem.

void test()
{
 boost::gregorian::date ofdate = boost::gregorian::day_clock::local_day();
 boost::posix_time::ptime dt = boost::posix_time::second_clock().local_time();
        
 dt = boost::posix_time::ptime(ofdate, dt.time_of_day());
 boost::posix_time::ptime dtcurrent = dt;

 std::ofstream fst;
 fst.open(L"c:\\test.test", std::ios_base::binary);
 for (int i = 0; i<1000;i++)
        {
                fst.write((char*)&i, sizeof(int));
                dtcurrent += boost::posix_time::time_duration(0,0, i);
                fst<<dtcurrent;
        }
 fst.close();

 std::ifstream ist(L"c:\\test.test", std::ios_base::binary);
 dtcurrent = dt;
 for (int i = 0; i<1000;i++)
        {
                dtcurrent += boost::posix_time::time_duration(0,0, i);
                int j = -1;
                ist.read((char*)&j, sizeof(int));
                boost::posix_time::ptime dt1;
                ist>>dt1;
                assert ( (dtcurrent == dt1) && (j == i) );
        }
 ist.close();
}
