std::time_get
<locale>
class CharT,
class InputIt = std::istreambuf_iterator <CharT>
Class template std::time_get encapsulates date and time parsing rules. The I/O manipulator std::get_time uses the std::time_get facet of the I/O stream's locale to convert text input to a std::tm object.
Inheritance diagram
If a std::time_get specialization is not guaranteed to be provided by the standard library (see below), the behaviors of its member functions (except the constructor and destructor) 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 -
InputItmust meet the requirements of LegacyInputIterator.

[edit] Example
Note: choose clang to observe the output. libstdc++ does not correctly implement the %b specifier: bug 78714.
#include <iomanip> #include <iostream> #include <locale> #include <sstream> int main() { std::tm t = {}; std::istringstream ss("2011-Februar-18 23:12:34"); ss.imbue(std::locale ("de_DE.utf-8")); ss >> std::get_time (&t, "%Y-%b-%d %H:%M:%S"); if (ss.fail()) std::cout << "Parse failed\n"; else std::cout << std::put_time (&t, "%c") << '\n'; }
Possible output:
