std::chrono::current_zone

< 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

#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
