在C++中获取时间戳的方法通常有以下几种：
使用#include <ctime>#include <iostream>int main() { time_t timestamp = time(nullptr); std::cout << "Current timestamp: " << timestamp << std::endl; return 0;}#include <chrono>#include <iostream>int main() { auto timestamp = std::chrono::system_clock::now().time_since_epoch().count(); std::cout << "Current timestamp: " << timestamp << std::endl; return 0;}#include <iostream>#include <windows.h>int main() { SYSTEMTIME st; GetSystemTime(&st); FILETIME ft; SystemTimeToFileTime(&st, &ft); ULARGE_INTEGER ul; ul.LowPart = ft.dwLowDateTime; ul.HighPart = ft.dwHighDateTime; time_t timestamp = ul.QuadPart / 10000000ULL - 11644473600ULL; std::cout << "Current timestamp: " << timestamp << std::endl; return 0;}
