Check the documentation for boost::locale at http://www.boost.org/doc/libs/1_59_0/libs/locale/doc/html/dates_times_timezones.html It is the same thing in booster, because the author Artyom did propose boost::locale and was accepted in the boost library itself. There you'll find enough documentation to move you further.
