C++ Boost: Get time with milliseconds

At the moment I am getting the date and time in the following way:

 std::string isoString = boost::posix_time::to_iso_string(boost::posix_time::second_clock::universal_time());
 std::string date = isoString.substr(0,8);
 std::string time = isoString.substr(9,16);

Problem: The milliseconds are missing and I need this information. How can I obtain the time with milliseconds?

Why not C++11? 

long long timestamp()
{
    return chrono::duration_cast<chrono::milliseconds>(chrono::system_clock::now().time_since_epoch()).count();
}

You can use boost::posix_time::microsec_clock :

 std::string isoString = boost::posix_time::to_iso_string(boost::posix_time::microsec_clock::universal_time());
 std::string date = isoString.substr(0,8);
 std::string time = isoString.substr(9,20);
