static std::chrono::time_point<std::chrono::system_clock> now() noexcept;		(since C++11)

Returns a time point representing the current point in time.

Parameters

(none)

Return value

A time point representing the current time.

Example

Run this code

#include <iostream>
#include <chrono>
 
int main()
{
    const auto now = std::chrono::system_clock::now();
    const std::time_t t_c = std::chrono::system_clock::to_time_t(now);
    std::cout << "The system clock is currently at " << std::ctime(&t_c);
}

Possible output:

The system clock is currently at Thu Mar 30 13:28:27 2023
