示例 1:
index.js
// Node.js program to demonstrate the
// Date.addMilliseconds() method
// Importing date-and-time module
const date = require('date-and-time')
// Creating object of current date
// and time using Date() method
const now = new Date();
// Adding Milliseconds to the existing date and time
// by using date.addMilliseconds() method
const value = date.addMilliseconds(now,24);
// Display the result
console.log("updated date and time :- " + value)
index.js
// Node.js program to demonstrate the
// Date.addMilliseconds() method
// Importing date-and-time module
const date = require('date-and-time')
// Creating object of current date
// and time using Date() method
const now = new Date();
now.setDate(20)
// Adding Milliseconds to the existing
// date and time by using
// date.addMilliseconds() method
const value = date.addMilliseconds(now,30);
// Display the result
console.log("updated date and time :- " + value)
使用以下命令运行index.js文件:
node index.js
输出:
updated date and time :- Fri Mar 19 2021 18:15:26 GMT+0530 (India Standard Time)
