获取c++中的当前时间

#include <iostream>
#include <ctime>

int main() {
    // 获取当前时间的秒数
    std::time_t currentTime = std::time(nullptr);

    // 将秒数转换为本地时间
    std::tm* localTime = std::localtime(&currentTime);

    // 输出当前时间
    std::cout << "当前时间：";
    std::cout << localTime->tm_year + 1900 << "-" << localTime->tm_mon + 1 << "-" << localTime->tm_mday << " ";
    std::cout << localTime->tm_hour << ":" << localTime->tm_min << ":" << localTime->tm_sec << std::endl;

    return 0;
}
