You might also consider a simple subclass of basic_entry that does the 
formatting in the constructor like:
struct my_entry : public basic_entry<>
{
    template <typename X> my_entry(
        const char* file,
        const int line,
        const char* fctn,
        const X& x
        ) : basic_entry<>()
    {
        basic_entry<>::operator << 
(boost::posix_time::microsec_clock::local_time())
                                << "," << file
                                << "," << line
                                << "," << fctn
                                << ":" << x;
    }
};

Then your macro would read:

#define LOG(tlm, x) tlm.log(my_entry(__FILE__, __LINE__, 
BOOST_CURRENT_FUNCTION, x))
