Timestamp between Javascript and PHP

Javascript:

I have object cell with something date

params.date = cell.getDate();
params.timestamp = cell.getDate().getTime() / 1000;
console.log(params);

Object {date: Thu May 09 2013 00:00:00 GMT+0800 (China Standard Time), timestamp: 1368028800}

Then I try to check timestamp in PHP

$date = '1368028800';
echo date('Y-m-d', $date);

2013-05-08

Difference in one day. Why?

The UNIX Timestamp 1368028800 corresponds to the date Wed, 08 May 2013 16:00:00 GMT. In your example, you are on the China Standard Time (GMT+8), so Javascript display the datetime for this timezone (8 hours later -> 09 May)

When you get timestamp from Javacript date object :

it output will be interms of milli-seconds

 <script>
        var d = new Date();
        alert(d.getTime());

     </script>

output : 1386746353000

Where as php date object timestamp interms of seconds

<?php 
        $date = new DateTime();
        echo $current_timestamp = $date->getTimestamp();
     ?>

output : 1386746353

So when you are going to use javascript date object timestamp with php date object you should divide timestamp of javascript by 1000 and use it in php

params.date = cell.getDate();

Returns the DATE not the TIME. 

params.timestamp = cell.getDate().getTime() / 1000;

is converting the date into a date+time - not reading the current time.

But even if you get the timestamp in javascript, the output of PHP's date function will depend on what timezone it is in.
