javascript new Date（）设置为GMT -4

Question

my server is on GMT -4 and all the records which go into the database are GMT -4 using

<?php date("Y-m-d H:i:s");?>

so if the time was 15:00:00 GMT +1 (my current timezone)
the time added to the database would be 10:00:00.

however when I use javascript new Date(); it gives it as

Thu Aug 29 2013 22:17:00 GMT+0100 (GMT Summer Time)

i have this function to convert the js date to php

$jsDate = $_REQUEST["date"];
$jsDateTS = strtotime($jsDate);
if ($jsDateTS !== false) 
{
$jsDateTS = date('Y-m-d H:i:s', $jsDateTS );
echo $jsDateTS."<br>";

but it writes 2013-08-29 22:17:00 and not 2013-08-28 17:17:00 which is what I need.

how do I convert my javascript new Date to GMT -4? is it possible or not?

thanks, and sorry if I am unclear in any way.

Answer 1

my solution was the following

client side

var date = new Date();
date = date.toUTCString();

server side

$date = date('Ymd H:i:s', strtotime($_REQUEST["date"]) );
