    \b Answer: You probably try to use incorrect \c std::locale object. 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 <b>I had installed global locale and try to write something to stream but still get wrong output?</b>
    For example:
    \code
    #include <boost/locale.hpp>
    #include <iostream>
    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 <boost/locale.hpp>
    #include <iostream>
    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
