Date.now() 如何在 javascript 中工作

Question

我正在尝试创建一个我可以很容易地与他人相关的时间值。

var created = Date.now() * 1000
var day_ago = Date.now() * 1000 - 24*60*60
if(created > day_ago){console.log('it was created in the last day')}

这似乎无法正常工作，任何人都知道我做错了什么

Answer 1

Date.now（） 将返回毫秒除以 1000 将以秒为单位进行转换。

var created = Date.now() / 1000
var day_ago = Date.now()/ 1000 - 24*60*60
if(created > day_ago){console.log('it was created in the last day')}

Answer 2

你必须除以 1000，而不是乘以

var created = Date.now() / 1000
var day_ago = Date.now() / 1000 - 24*60*60
if(created > day_ago){console.log('it was created in the last day')}
