我使用这个 jQuery 教程制作了一个时钟：
http://tutorialzine.com/2009/12/colorful-clock-jquery-css/
但是这款手表需要客户端的时间，我会使用这个 jQuery 来获取服务器时间，我该如何获取服务器时间呢？

script.js
$(document).ready(function(){
/* This code is executed after the DOM has been completely loaded */
$('#fancyClock').tzineClock();
});
jquery.tzineClock.js
(function($){
// A global array used by the functions of the plug-in:
var gVars = {};
// Extending the jQuery core:
$.fn.tzineClock = function(opts){
// "this" contains the elements that were selected when calling the plugin: $('elements').tzineClock();
// If the selector returned more than one element, use the first one:
var container = this.eq(0);
if(!container)
{
try{
console.log("Invalid selector!");
} catch(e){}
return false;
}
if(!opts) opts = {};
var defaults = {
/* Additional options will be added in future versions of the plugin. */
};
/* Merging the provided options with the default ones (will be used in future versions of the plugin): */
$.each(defaults,function(k,v){
opts[k] = opts[k] || defaults[k];
})
// Calling the setUp function and passing the container,
// will be available to the setUp function as "this":
setUp.call(container);
return this;
}
function setUp()
{
// The colors of the dials:
var colors = ['orange','blue','green'];
var tmp;
for(var i=0;i<3;i++)
{
// Creating a new element and setting the color as a class name:
tmp = $('<div>').attr('class',colors[i]+' clock').html(
'<div class="display"></div>'+
'<div class="front left"></div>'+
'<div class="rotate left">'+
'<div class="bg left"></div>'+
'</div>'+
'<div class="rotate right">'+
'<div class="bg right"></div>'+
'</div>'
);
// Appending to the container:
$(this).append(tmp);
// Assigning some of the elements as variables for speed:
tmp.rotateLeft = tmp.find('.rotate.left');
tmp.rotateRight = tmp.find('.rotate.right');
tmp.display = tmp.find('.display');
// Adding the dial as a global variable. Will be available as gVars.colorName
gVars[colors[i]] = tmp;
}
// Setting up a interval, executed every 1000 milliseconds:
setInterval(function(){
var currentTime = new Date();
var h = currentTime.getHours();
var m = currentTime.getMinutes();
var s = currentTime.getSeconds();
animation(gVars.green, s, 60);
animation(gVars.blue, m, 60);
animation(gVars.orange, h, 24);
},1000);
}
function animation(clock, current, total)
{
// Calculating the current angle:
var angle = (360/total)*(current+1);
var element;
if(current==0)
{
// Hiding the right half of the background:
clock.rotateRight.hide();
// Resetting the rotation of the left part:
rotateElement(clock.rotateLeft,0);
}
if(angle<=180)
{
// The left part is rotated, and the right is currently hidden:
element = clock.rotateLeft;
}
else
{
// The first part of the rotation has completed, so we start rotating the right part:
clock.rotateRight.show();
clock.rotateLeft.show();
rotateElement(clock.rotateLeft,180);
element = clock.rotateRight;
angle = angle-180;
}
rotateElement(element,angle);
// Setting the text inside of the display element, inserting a leading zero if needed:
clock.display.html(current<10?'0'+current:current);
}
function rotateElement(element,angle)
{
// Rotating the element, depending on the browser:
var rotate = 'rotate('+angle+'deg)';
if(element.css('MozTransform')!=undefined)
element.css('MozTransform',rotate);
else if(element.css('WebkitTransform')!=undefined)
element.css('WebkitTransform',rotate);
// A version for internet explorer using filters, works but is a bit buggy (no surprise here):
else if(element.css("filter")!=undefined)
{
var cos = Math.cos(Math.PI * 2 / 360 * angle);
var sin = Math.sin(Math.PI * 2 / 360 * angle);
element.css("filter","progid:DXImageTransform.Microsoft.Matrix(M11="+cos+",M12=-"+sin+",M21="+sin+",M22="+cos+",SizingMethod='auto expand',FilterType='nearest neighbor')");
element.css("left",-Math.floor((element.width()-50)/2));
element.css("top",-Math.floor((element.height()-50)/2));
}
}
})(jQuery)
我需要更改每个 .js 以获得服务器时间？抱歉，几周前我开始使用 jQuery，我还在学习，我不知道如何在 jQuery 中改变一些很棒的东西。

我写了
亲爱的 MarZab，我照你说的做，但它不起作用，而不是时间以小时显示“NaN”，分钟和秒显示相同。
我写：
var clienttime = new Date();
var servertime = 1368597301000; // *mili*seconds
// snip
setInterval(function () {
var currentTime = new Date();
currentTime.setTime(currentTime.getTime() + servertime.time - clienttime.time);
var h = currentTime.getHours();
var m = currentTime.getMinutes();
var s = currentTime.getSeconds();
animation(gVars.green, s, 60);
animation(gVars.blue, m, 60);
animation(gVars.orange, h, 24);
}, 1000);
所以我试着把
var clienttime = new Date();
var servertime = 1368597301000; // *mili*seconds
在函数内部，但即使这样也行不通。
我需要做什么？
