std::chrono:: current_zone

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.

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()
{
    try
    {
        const std::chrono::zoned_time cur_time
        {
            std::chrono::current_zone(), // may throw
            std::chrono::system_clock::now()
        };
        std::cout << cur_time << '\n';
    }
    catch(const std::runtime_error& ex)
    {
        std::cerr << ex.what() << '\n';        
    }
}
