text_multifile_backend как установить динамическую дату для имени файла

Я пытаюсь установить динамическую дату для моего многофайлового логгера Boost, чтобы отдельные файлы журналов для повседневного использования находились в разных файлах, например: ‘log ___ 2018-07-10__172.17.18.199.log’.
Я не хочу устанавливать дату для каждой функции в моем коде как BOOST_LOG_SCOPED_THREAD_TAG! Я хочу, чтобы это делал регистратор ядра ядра, и я просто хочу установить локальные часы в глобальных атрибутах, но я НЕ знаю, как это сделать 🙁
Вот мне код:

#include <boost/shared_ptr.hpp>
#include <boost/thread/thread.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
#include <boost/log/expressions.hpp>
#include <boost/log/sources/severity_logger.hpp>
#include <boost/log/common.hpp>
#include <boost/log/attributes.hpp>
#include <boost/log/sources/logger.hpp>
#include <boost/log/sinks/sync_frontend.hpp>
#include <boost/log/sinks/text_multifile_backend.hpp>
#include <boost/log/support/date_time.hpp>

enum SeverityLevel {
TRACE,
DEBUG,
WARNING,
INFO,
ERROR,
FATAL
};

enum

THREAD_COUNT = 5,
LOG_RECORDS_TO_WRITE = 10
};

boost::log::sources::severity_logger_mt< SeverityLevel > myLogger;

#define LOG_ERROR   BOOST_LOG_SEV(myLogger, ERROR)
#define LOG_FATAL   BOOST_LOG_SEV(myLogger, FATAL)

#define LOG_DEBUG   BOOST_LOG_SEV(myLogger, DEBUG)

{

}
}

{

}

но получил эту ошибку компоновщика:

ErrorC2664 'boost::log::v2s_mt_nt6::aux::light_function<void (boost::log::v2s_mt_nt6::basic_formatting_ostream<char,std::char_traits<char>,std::allocator<char>> &,const boost::posix_time::ptime &)>::result_type boost::log::v2s_mt_nt6::aux::light_function<void (boost::log::v2s_mt_nt6::basic_formatting_ostream<char,std::char_traits<char>,std::allocator<char>> &,const boost::posix_time::ptime &)>::operator ()(boost::log::v2s_mt_nt6::basic_formatting_ostream<char,std::char_traits<char>,std::allocator<char>> &,const boost::posix_time::ptime &) const': cannot convert argument 1 from 'boost::log::v2s_mt_nt6::basic_formatting_ostream<wchar_t,std::char_traits<wchar_t>,std::allocator<wchar_t>>' to 'boost::log::v2s_mt_nt6::basic_formatting_ostream<char,std::char_traits<char>,std::allocator<char>> &' sample.boost.asio   e:\programming\c++\boost libraries\boost_1_66_0\boost\log\utility\functional\bind.hpp   93

Может ли кто-нибудь объяснить мне, почему это произошло ???

заранее спасибо
