将日期转换为毫秒到目前为止

Question

I ran into a strange issue. I am sending a date that I converted to milliseconds using Javascript to my controller. There, I convert the milliseconds to a time stamp in PHP. It seems to get the date part of it right, but the time is totally off. Can anyone please tell me what am I missing? The code is below.

javascript

var d = new Date("13 October 2014 11:13:00");    
document.write(d.getTime() + " milliseconds since 1970/01/01");

result

1413191580000

php

echo date("Y-m-d H:i:s", 1413191580000/1000);

result

2014-10-13 02:13:00

I'm guessing this is happening because you have a date with a different timezone returned from the client than the server. JavaScript's Date.prototype.getTime() returns a UTC timestamp according to the ECMAScript standard (§15.9.1.1). Standardize the time zones between client and server and then you can have dates be the same in both. I always deal with dates in UTC on the server and then do client side timezone localizations.
