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.

Type requirements
- OutputIt must meet the requirements of OutputIterator. |
Specializations
Two standalone (locale-independent) full specializations and two partial specializations are provided by the standard library:
| 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, OutputIt> | creates narrow string representations of date and time using custom output iterator |
std::time_put<wchar_t, OutputIt> | creates wide string representations of date and time using custom output iterator |
In addition, every locale object constructed in a C++ program implements its own (locale-specific) versions of these specializations.
Member types
| Member type | Definition |
|---|---|
char_type | CharT |
iter_type | OutputIt |
Member functions
| constructs a new time_put facet (public member function) | |
| (destructor)
| destructs a time_put facet (protected member function) |
invokes do_put (public member function) |
Member objects
| static std::locale::id id | id of the locale (public member object) |
Protected member functions
| [virtual] | formats date/time and writes to output stream (virtual protected member function) |
Example
#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"));
// this I/O manipulator std::put_time uses std::time_put<wchar_t>
out << std::put_time(std::localtime(&t), L"%A %c") << '\n';
}Output:
