javascript 将纪元字符串转换为日期对象

javascript convert from epoch string to Date object

提问by fortuneRice

var myDate = new Date();
var epoch = myDate.getTime(); //1318023197289 number of ms since epoch
var unixEpoch = Math.round(epoch/1000)

1. How do you convert epochback to a Date object?
2. Can you also convert unixEpoch back to a Date object?

1. 如何转换epoch回 Date 对象？
2. 您还可以将 unixEpoch 转换回 Date 对象吗？

回答by Matt

var date = new Date(1318023197289);

And, since unixEpoch is simply epoch / 1000, you can similarly multiply the argument in the constructor by 1000.

而且，由于 unixEpoch 只是 epoch / 1000，您可以类似地将构造函数中的参数乘以 1000。
