Hi, I've built todays cvs boost library but date_time lib seems to have the same error as in 1.32 version. That is: wstring wts = _T("20021017T231217.12345"); wdate_facet* date_facet = new wdate_facet; wtime_facet* time_facet = new wtime_facet; ptime pt1( from_iso_string( convert_string_type<_TCHAR, char>(wts) ) ); long Y = pt1.date().year(); long M = pt1.date().month(); long d = pt1.date().day(); long h = pt1.time_of_day().hours(); long m = pt1.time_of_day().minutes(); long s = pt1.time_of_day().seconds(); long f = pt1.time_of_day().fractional_seconds(); wcout << L"Components of pt1:" << endl << L"Year: " << Y << endl << L"Month: " << M << endl << L"Day: " << d << endl << L"Hours: " << h << endl << L"Minutes: " << m << endl << L"Seconds: " << s << endl << L"Microseconds: " << f << endl; ptime pt2( gregorian::date(2002, 10, 17), posix_time::time_duration(23, 12, 17, 12345) ); wcout << pt2 << endl; Y = pt2.date().year(); M = pt2.date().month(); d = pt2.date().day(); h = pt2.time_of_day().hours(); m = pt2.time_of_day().minutes(); s = pt2.time_of_day().seconds(); f = pt2.time_of_day().fractional_seconds(); wcout << L"Components of pt2:" << endl << L"Year: " << Y << endl << L"Month: " << M << endl << L"Day: " << d << endl << L"Hours: " << h << endl << L"Minutes: " << m << endl << L"Seconds: " << s << endl << L"Microseconds: " << f << endl; Output is: Components of pt1: Year: 2002 Month: 10 Day: 17 Hours: 23 Minutes: 12 Seconds: 17 Microseconds: 0 2002-Oct-17 23:12:17.012345 Components of pt2: Year: 2002 Month: 10 Day: 17 Hours: 23 Minutes: 12 Seconds: 17 Microseconds: 12345 Another question is about wide char support. As far as I understand, wstring is supported only through stringstream and facets? TIA -- Serge
