std::time_put_byname is a std::time_put facet which encapsulates time and date formatting rules of the locale specified at its construction.
Two specializations are provided by the standard library
Defined in header
<locale> | |
std::time_put_byname<char, OutputIterator> | narrow/multibyte time formatting |
std::time_put_byname<wchar_t, OutputIterator> | wide string time formatting |

Member functions
invokes do_put (public member function of std::time_put<CharT,OutputIt> )

formats date/time and writes to output stream (virtual protected member function of std::time_put<CharT,OutputIt> )

Example
This example prints current time using the "C" locale with the time_put facet replaced by various time_put_byname facets
Run this code
#include <iostream> #include <ctime> #include <iomanip> #include <codecvt> int main() { std::time_t t = std::time(NULL); std::wbuffer_convert<std::codecvt_utf8<wchar_t>> conv(std::cout.rdbuf()); std::wostream out(&conv); out.imbue(std::locale(out.getloc(), new std::time_put_byname<wchar_t>("ja_JP"))); out << std::put_time(std::localtime(&t), L"%A %c") << '\n'; out.imbue(std::locale(out.getloc(), new std::time_put_byname<wchar_t>("ru_RU.utf8"))); out << std::put_time(std::localtime(&t), L"%A %c") << '\n'; out.imbue(std::locale(out.getloc(), new std::time_put_byname<wchar_t>("sv_SE.utf8"))); out << std::put_time(std::localtime(&t), L"%A %c") << '\n'; }
