    chrono::time_point<chrono::system_clock, chrono::microseconds> tpMicro
            = chrono::time_point_cast<chrono::microseconds>(chrono::system_clock::now());
    // (微秒精度的)时间点 => (微秒精度的)时间戳
    time_t totalMicroSeconds = tpMicro.time_since_epoch().count();

    long long currentTime = ((long long)totalMicroSeconds)/1000;

    return currentTime;
