Defined in header <chrono>
class time_zone;		(since C++20)

The class time_zone represents all time zone transitions for a specific geographic area.

Users cannot construct time_zone objects. The library implementation creates time_zone objects when it initializes the time zone database and provides const access to these objects.

time_zone is not copyable but does have a defaulted move constructor and a defaulted move assignment operator. However, as users have only const access to time_zone objects, these functions cannot be called in user code without invoking undefined behavior.

Member functions

name	obtains the name of this time_zone (public member function)
get_info	obtain information associated with a sys_time or local_time (public member function)
to_sys	converts a local_time in this time zone to a sys_time (public member function)
to_local	converts a sys_time to a local_time in this time zone (public member function)

Nonmember functions

operator==operator<=> (C++20)

compares two time_zone objects (function)
