NAME

std::chrono::current_zone - std::chrono::current_zone

Synopsis

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:
