Я написал этот код в node.js, но response.timing не определено.В чем проблема с моей треской> 

const request = require("request");
request.get({
  time : true,
  url : 'https://www.bbc.com/',

},function(err, response){
  console.log('Request time in ms', response.timings);
});

это мой код: 

const request = require("request");
request.get({
  time : true,
  url : 'http://worldtimeapi.org/api/ip'

},function(err, response){
  console.log('Request time in ms', response.timings);
  console.log(response);
});

а это вывод: 

node app.js 
Request time in ms undefined
