All Boost.Locale tools relay on \c std::locale object's facets. The locale object should be generated with \ref boost::locale::generator "generator" class and then passed to the function or alternatively global locale should be set using \c std::locale::global() function such that global locale (and default created one) would have required facets to use. - \anchor faq_number I had installed global locale and try to write something to stream but still get wrong output? For example: \code #include #include int main() { boost::locale::generator gen; std::locale::global(gen("")); std::cout << boost::locale::as::date << std::time(0) << std::endl; } \endcode Prints a number instead of a date. \n \b Answer: You forget to imbue the locale to the stream. Changing the global locale does not affect the locale in existing \c iostream objects. Thus because \c std::out and other global streams were created before changing the global locale Boost.Locale manipulators have no effect. You need to write: \code #include #include int main() { boost::locale::generator gen; std::locale l = gen(""); std::locale::global(l); std::cout.imbue(l); std::cout << boost::locale::as::date << std::time(0) << std::endl; } \endcode */
