These deduction guides normalizeDuration to a minimum resolution ofstd::chrono::seconds, and provide correct handling for time zone names specified using types convertible tostd::string_view.

3-6) Ifstd::is_convertible_v<TimeZonePtrOrName,std::string_view> istrue, the deduced second template argument isconststd::chrono::time_zone*. Otherwise it isstd::remove_cvref_t<TimeZonePtrOrName>.
