Summary: from_ftime incorrectly processes FILETIME filled with zeros

Initial Comment:
using namespace boost::posix_time;
using namespace boost::gregorian;

FILETIME ft;
ZeroMemory( &ft, sizeof( ft ) );

ptime pt = from_ftime<ptime>( ft );

if ( pt.is_special() ) {
   // Never fall into this branch!
   std::cout << "ERROR";
} else {
   // Exception: boost::gregorian::bad_year
   std::cout << boost::format("%1%") % pt.date().year();
}

I suppose that when FILETIME is filled with zeroes,
from_ftime() should return not_a_date_time. But it does
not do this.
