Defined in header <chrono>
const std:: chrono :: time_zone * current_zone ( ) ;
(since C++20)

Convenience function for obtaining local time zone from the time zone database. Equivalent to std:: chrono :: get_tzdb ( ) . current_zone ( ) .

Exceptions

std::runtime_error if this is the first reference to the time zone database and the time zone database cannot be initialized.

Notes

A call to this function that is the first reference to the time zone database will cause it to be initialized.

Example

Run this code 
#include <chrono>
#include <iostream>
 
int main() {
    const std::chrono::zoned_time cur_time{ std::chrono::current_zone(),
                                            std::chrono::system_clock::now() };
    std::cout << cur_time << '\n';
}

Possible output: 

2021-09-13 19:46:42.249182012 MAGT
