# std::chrono::current_zone

From cppreference.com
< cpp‎ | chrono

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:
