Std put_time

std:: put_time. template <class charT> /*unspecified*/ put_time (const struct tm* tmb, const charT* fmt); Put date and time. Inserts the representation of the time and date information pointed by tmb, formatting it as specified by argument fmt Class template std::time_put encapsulates date and time formatting rules. The I/O manipulator std::put_time uses the std::time_put facet of the I/O stream's locale to generate text representation of an std::tm object I want understand how to work std::put_time, and how can I get date stamp in YYYY/MM/DD HH:MM:SS format. Now I write somthing like this: std::chrono::time_point<std::chrono::system_clock>.

Converts the calendar date and time stored in the std::tm object pointed to by t into a character string, according to the format string [fmtbeg, fmtend).The format string is the same as used by std:: strftime, but each format specifier is processed by an individual call to do_put(), which can be customized by extending this facet When used in an expression out << put_time (tmb, fmt), converts the date and time information from a given calendar time tmb to a character string according to format string fmt, as if by calling std::strftime, std::wcsftime, or analog (depending on CharT), according to the std::time_put facet of the locale currently imbued in the output stream. Formats the time value in the tm structure pointed by t into a sequence of characters. The function writes the characters resulting from the formatting operation into the sequence whose first character is pointed by s. An iterator to the character right after the last element written to the output sequence is returned by the function

Internally, the function accesses the input sequence by first constructing an object of type basic_istream::sentry.Then (if evaluating the sentry object is true), it calls time_get::get.

Exampl 关于c++11时间函数std::put_time在g++4.8.5上不能使 Thanks! I pushed a merge with master, a comment cleanup (we generally prefer comments to be either sentence fragments or complete sentences with proper punctuation, not a mix), and the code movement that @mnatsuhara requested (no other changes) - with _Getloctxt at the end of the file, the diff is much simpler, and we don't need to worry about the placement of class template specializations These functions are not safe to use in a multithreaded environment as introduced with C++11 because they return a pointer to an internal static struct. This is especially annoying since C++11 introduced the convenient function std::put_time which is nearly unusable for the same reason. Why is this so fundamental broken or do I overlook something

Just a warning - my recent testing suggests that some of the formatting flags within C++11 std::put_time are currently broken. So the following code example using %F doesn't work for me. However the manual workaround I have provided does std::chrono::system_clock::to_time_t() (system clock is just example). std::localtime() std::put_time() std::mktime() The only ways to print time are either std::ctime() and std::put_time() (not counting the implement by hand approach). So let's follow the thread and find its end and test it Hello, keep up the great work with GCC. I wanted to bring to your attention that the extended <iomanip> manipulators std::get_time and std::put_time have not been declared (C++11, section 27.7.5) Consider these functions that allow to convert std::chrono::time_point to/from std::string with a predefined date-time format. constexpr size_t log10(size_t xx) { return xx == 1 ? 0 : 1 + log10(xx.. The C++ standard library does not provide a proper date type. C++ inherits the structs and functions for date and time manipulation from C. To access date and time related functions and structures, you would need to include <ctime> header file in your C++ program

error: namespace std has no member get_time I know the Intel compiler doesn't support some C++17 features, like std::filesystem, but I would've thought a C++11 feature was a no-brainer. Am I missing something obvious? Any ideas are greatly appreciated. The code compiles fine with g++. Thanks It is easy to see that the generated code is identical, and thus there is no overhead associated with the sys_days type.
