date_time io bug in 1.33?

Hi, The following code looks pretty suspicious to me: extern const wchar_t* pts; // pts = L"2004071" std::wistringstream wiss(pts); wtime_input_facet* wtif = new wtime_input_facet; wtif->set_iso_format(); wiss.imbue(std::locale(std::locale::classic(), wtif)); ptime pt; wiss >> pt; std::string dbgs = to_iso_string(pt); // dbgs == "20040711T000000" Seems to be a bug? TIA -- Serge
