C++ Chrono Current Time: Quick Guide

In C++, you can use the system_clock from the header to get the current time. Here is a simple example code:

#include <iostream>
#include <chrono>

int main() {
    // 获取当前时间点
    auto now = std::chrono::system_clock::now();
    
    // 将当前时间点转换为时间戳
    auto now_time = std::chrono::system_clock::to_time_t(now);
    
    // 输出当前时间戳
    std::cout << "Current time: " << std::ctime(&now_time) << std::endl;
    
    return 0;
}

This code will output the current timestamp, and you can format the time information as needed.
