customDevLogger_Morgan

logger.format("mine", function(tokens, req, res) {
	var dt = new Date;
	
// Key being: all the logging format added internally are available directly as methods: .dev/.default/.full etc
	return "" + dt.getDate() + dt.getMonth() + dt.getYear() +"_"+ dt.getHours() + dt.getMinutes() + dt.getSeconds() + " : " + logger.dev(tokens, req, res);
});
