I use following code

#include <iomanip>
#include <iostream>
#include <locale>
#include <sstream>

int main() {
    std::tm t = {};
    std::istringstream ss("2011-Februar-18 23:12:34");
    ss.imbue(std::locale("de_DE.utf-8"));
    ss >> std::get_time(&t, "%Y-%b-%d %H:%M:%S");

    if (ss.fail())
        std::cout << "Parse failedn";
    else
        std::cout << std::put_time(&t, "%c") << 'n';
}

in “>>” it throw err:
