How to convert milliseconds into a readable date?
提问by Christian Fazzini
The following:
下列：
new Date(1324339200000).toUTCString()
Outputs:
输出：
"Tue, 20 Dec 2011 00:00:00 GMT"
I need it to return Dec 20. Is there a better method I can use besides toUTCString()? I am looking for any way to parse through milliseconds, to return a human readable date.
我需要它返回Dec 20。除了我可以使用的更好的方法toUTCString()吗？我正在寻找任何方法来解析毫秒，以返回人类可读的日期。

Using the library Datejs you can accomplish this quite elegantly, with its toStringformat specifiers: http://jsfiddle.net/TeRnM/1/.
使用库 Datejs，您可以通过其toString格式说明符非常优雅地完成此操作：http: //jsfiddle.net/TeRnM/1/。
var date = new Date(1324339200000);
date.toString("MMM dd"); // "Dec 20"

You can use datejs and convert in different formate. I have tested some formate and working fine.
您可以使用 datejs 并转换为不同的格式。我已经测试了一些甲酸盐并且工作正常。
var d = new Date(1469433907836);
d.toLocaleString() // 7/25/2016, 1:35:07 PM
d.toLocaleDateString() // 7/25/2016
d.toDateString() // Mon Jul 25 2016
d.toTimeString() // 13:35:07 GMT+0530 (India Standard Time)
d.toLocaleTimeString() // 1:35:07 PM
d.toISOString(); // 2016-07-25T08:05:07.836Z
d.toJSON(); // 2016-07-25T08:05:07.836Z
d.toString(); // Mon Jul 25 2016 13:35:07 GMT+0530 (India Standard Time)
d.toUTCString(); // Mon, 25 Jul 2016 08:05:07 GMT

No, you'll need to do it manually.
不，您需要手动执行此操作。
function prettyDate(date) {
var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
return months[date.getUTCMonth()] + ' ' + date.getUTCDate() + ', ' + date.getUTCFullYear();
}

This is a solution. Later you can split by ":" and take the values of the array
这是一个解决方案。稍后您可以通过“：”拆分并获取数组的值
/**
* Converts milliseconds to human readeable language separated by ":"
* Example: 190980000 --> 2:05:3 --> 2days 5hours 3min
*/
function dhm(t){
var cd = 24 * 60 * 60 * 1000,
ch = 60 * 60 * 1000,
d = Math.floor(t / cd),
h = '0' + Math.floor( (t - d * cd) / ch),
m = '0' + Math.round( (t - d * cd - h * ch) / 60000);
return [d, h.substr(-2), m.substr(-2)].join(':');
}
//Example
var delay = 190980000;
var fullTime = dhm(delay);
console.log(fullTime);

You can do it with just a few lines of pure js codes.
只需几行纯 js 代码即可完成。
var date = new Date(1324339200000);
var dateToStr = date.toUTCString().split(' ');
var cleanDate = dateToStr[2] + ' ' + dateToStr[1] ;
console.log(cleanDate);
returns Dec 20. Hope it helps.
12 月 20 日返回。希望它有所帮助。

Building on lonesomeday's example(upvote that answer not this one), I ran into this output:
以lonesomeday的示例为基础（赞成答案不是这个），我遇到了这个输出：
undefined NaN, NaN
undefined NaN, NaN
var datetime = '1324339200000'; //LOOK HERE
function prettyDate(date) {
var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
return months[date.getUTCMonth()] + ' ' + date.getUTCDate() + ', ' + date.getUTCFullYear();
}
console.log(prettyDate(new Date(datetime))); //AND HEREThe cause was using a string as input. To fix it, prefix the string with a plus sign:
原因是使用字符串作为输入。要修复它，请在字符串前加上加号：
prettyDate(new Date(+datetime));
prettyDate(new Date(+datetime));
var datetime = '1324339200000';
function prettyDate(date) {
var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',

return months[date.getUTCMonth()] + ' ' + date.getUTCDate() + ', ' + date.getUTCFullYear();
}
console.log(prettyDate(new Date(+datetime))); //HERETo add Hours/Minutes to the output:
将小时/分钟添加到输出：
var datetime = '1485010730253';
function prettyDate(date) {
var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
return months[date.getUTCMonth()] +' '+ date.getUTCDate()+ ', '+ date.getUTCHours() +':'+ date.getUTCMinutes();

I just tested this and it works fine
我刚刚测试了这个，它工作正常
var d = new Date(1441121836000);
The data object has a constructor which takes milliseconds as an argument.
数据对象有一个以毫秒为参数的构造函数。
