template<class Duration > std::chrono::sys_info get_info(const std::chrono::sys_time<Duration>& tp) const;		(since C++20)
template< class Duration > std::chrono::local_info get_info(const std::chrono::local_time<Duration>& tp) const;		(since C++20)

Obtains information about this time zone at the time point tp.

Return value

1) A std::chrono::sys_info structure i containing the time zone information in effect for this time zone at the time point tp. tp will be in the range [i.begin, i.end).

2) A std::chrono::local_info structure containing information about the local time tp in this time zone.
