std::time_put
<locale>
class CharT,
class OutputIt = std::ostreambuf_iterator <CharT>
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.
Inheritance diagram
If a std::time_put specialization is not guaranteed to be provided by the standard library (see below), the behaviors of its put() and do_put() are not guaranteed as specified.

[edit] Specializations
The standard library is guaranteed to provide the following specializations (they are required to be implemented by any locale object):
<locale> In addition, the standard library is also guaranteed to provide every specialization that satisfies the following type requirements:
-
CharTis one of char and wchar_t, and -
OutputItmust meet the requirements of LegacyOutputIterator.
