How to get the current timestamp in C++?
In C++, you can use the std::chrono library to retrieve the current timestamp. Here is an 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(以秒为单位)
std::time_t timestamp = std::chrono::system_clock::to_time_t(now);
// 打印时间戳
std::cout << "当前时间戳:" << timestamp << std::endl;
return 0;
}
In the given code snippet, the current time is first retrieved using the std::chrono::system_clock::now() function, then converted to a timestamp using std::chrono::system_clock::to_time_t() function. Finally, the timestamp is printed out.
