How to convert milliseconds to a date string?
提问by alexh
I get a miliseconds string from the server like this: 1345623261.
我从服务器得到一个毫秒字符串，如下所示：1345623261。
How can i convert this into a normal date format, e.g. 30.08.2012?
我如何将其转换为正常的日期格式，例如 30.08.2012？
I attempted using setMilliseconds, like so:
我尝试使用setMilliseconds，像这样：
new Date().setMilliseconds(time_posted).toLocaleString();
But this doesn't work. How to do that?
但这不起作用。怎么做？

Assuming time_postedis a number representing timestamp, which is expressed in seconds (judging by the number of digits) - multiply it by 1000 to get a representation in milliseconds, and pass the result to the Date's constructor:
假设time_posted是一个表示时间戳的数字，以秒表示（根据位数判断） - 将其乘以 1000 以获得以毫秒为单位的表示，并将结果传递给Date构造函数：
(new Date(time_posted * 1000)).toLocaleString();
// -> "Wed Aug 22 2012 11:14:21 GMT+0300 (Jerusalem Daylight Time)"
To take this a bit further and achieve something closer to what you denoted in the question, use toLocaleDateString(), which will produce a more human-readable form:
为了更进一步并实现更接近您在问题中表示的内容，请使用toLocaleDateString()，这将产生更易于阅读的形式：
(new Date(time_posted * 1000)).toLocaleDateString();
// -> "Wednesday, August 22, 2012"
