Hi

Thank you for posting here.

I suggest you could try to use system_clock::now to return the current time. And then you could convert the timestamp to ISO8601 format with strftime function.

Here is a demo:

std::chrono::system_clock::time_point now = std::chrono::system_clock::now();
    time_t current_time = std::chrono::system_clock::to_time_t(now);
    char buf[32];
    strftime(buf, sizeof(buf), "%FT%TZ", gmtime(&current_time));
    //also you can use
    //strftime(buf, sizeof(buf), "%Y-%m-%dT%H:%M:%SZ", gmtime(&current_time));
    std::string s_CurrentTime(buf);
    std::cout<<buf<<std::endl;
