These deduction guides normalize Duration to a minimum resolution of std::chrono::seconds , and provide correct handling for time zone names specified using types convertible to std::string_view .
3-6) If std::is_convertible_v <TimeZonePtrOrName, std::string_view > is true, the deduced second template argument is const std::chrono::time_zone *. Otherwise it is std::remove_cvref_t <TimeZonePtrOrName>.
