Variables
static const std::array< std::string, 9 >	formats_
static const std::array< std::string, 3 >	locales_ = {{ "C", "en_US.UTF-8", "" }}
static std::mutex	tm_mutex_
	The std::localtime and std::gmtime functions are not thread safe, due to their shared internal state. Make sure that we can use them from multiple threads. More...
