var time = require('time');exports.handler = (event, context, callback) => {    var currentTime = new time.Date();     currentTime.setTimezone("America/New_York");    callback(null, {        statusCode: '200',        body: 'Time in New York : ' + currentTime.toString(),    });};

2. Create the packt.yaml file with the following code. This is a SAM template file to define the resources. It will define a Lambda function which will be triggered by the API gateway:
