PHP时区问题

Question

I am using the countdown here http://keith-wood.name/countdown.html and I have added the server time and everything but now with daylight savings my application adds an extra hour to all countdown times at http://www.artfido.com

I have tried changing the server time to not update with daylight savings but my countdown still has an hour added.

UTC time is +10 but don't know how to change to not have the additional hour.

Code sample

server-time.php  
<?php 
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1 
header("Expires: Fri, 1 Jan 2010 00:00:00 GMT"); // Date in the past 
header("Content-Type: text/plain; charset=utf-8"); // MIME type 
$now = new DateTime();
echo $now->format("M j, Y H:i:s O")."
";
?>

Countdown script
$('#defaultCountdown').countdown({
until: endAuction,
serverSync: serverTime,
timezone: +10,
format: 'DHMS',...

function serverTime() { 
var time = null; 
$.ajax({url: 'server-time.php?random=' + Math.floor(Math.random() * 1000000), 
 async: false, dataType: 'text', 
 success: function(text) { 
 time = new Date(text); 
}, error: function(http, message, exc) { 
time = new Date(); 
}}); 
return time; 
}

You have used code this way:

function serverTime() {
    var time = null;
    $.ajax({url: 'cgi/server-time.php?random=' + Math.floor(Math.random() * 1000000),
        async: false, dataType: 'text',
        success: function(text) {
            time = new Date(text);
        }, error: function(http, message, exc) {
            time = new Date();
    }});
    return time;
}

This function, doesn't return anything because the AJAX Call is asynchronous. One good way, is to do it in the success function. I meant the initialization of the timer.

Because, when you call this serverTime() function, it always returns null. It is not instant. Do one thing. Have a function called, startTimer(time) and pass the server's time in the time variable to the startTimer() and inside the function, define this way:

function startTimer(time)
{
    var endAuction = "";
    $(function () {
        endAuction = new Date(
            2012,
            10,
            08,
            12,
            24,
            26                                                                );
        $('#defaultCountdown8077').countdown('destroy')
        $('#defaultCountdown8077').countdown({
            until: endAuction,
            serverSync: time,
            timezone: +10,
            format: 'DHMS',
            expiryUrl: 'http://www.artfido.com'
        });
    });
}

Also the serverTime(); you are calling somewhere in the middle, and in no way, it would be useful.

Your JavaScript code would be:

function initTimer() {
    var time = null;
    $.ajax({url: 'cgi/server-time.php?random=' + Math.floor(Math.random() * 1000000),
        async: false, dataType: 'text',
        success: function(text) {
            time = new Date(text);
            startTimer(time);
        }
    });
}
