@AaronBallman the `std::print` thing was illistrative, this works in C++17 (well, 11) ```cpp std::stringstream buf; // this is the line that ensure we are not affected by locales buf.imbue(std::locale("C")); std::time_t t = std::time(nullptr); std::tm tm = *std::localtime(&t); buf << std::put_time(&tm, "%c"); std::string str = buf.str(); // do whatever with that string ``` https://github.com/llvm/llvm-project/pull/99075 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
