Defined in header `<locale>`

template< class CharT, class OutputIterator = std::ostreambuf_iterator<CharT> > class time_put : public std::locale::facet;

Class template std::time_put encapsulates date and time formatting rules. The I/O manipulator std::putt_time uses the std::time_put facet of the I/O stream's locale to generate text representation of an std::tm object.

Two specializations and two partial specializations are provided by the standard library and are implemented by all locale objects created in a C++ program:

Defined in header `<locale>`

std::time_put<char>	creates narrow string representations of date and time

std::time_put<wchar_t>	creates wide string representations of date and time

std::time_put<char, OutputIterator>	creates narrow string representations of date and time using custom output iterator

std::time_put<wchar_t, OutputIterator>	creates wide string representations of date and time using custom output iterator

#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("ja_JP"));
    out << std::put_time(std::localtime(&t), L"%A %c") << '\n'; // uses std::time_put<wchar_t>
}
