js实现当前世界各国时区时间代码。主要有：北京时间，孟买时间，纽约时间，东京时间，巴黎时间，悉尼时间等。

使用方法

1、head引入css文件

<style>
	body {
		background-image: url("img/bj.jpg");
		background-size: cover;
		background-repeat: no-repeat;
	}

	#container {
		position: absolute;
		left: 0;
		right: 0;
		top: 0;
		bottom: 0;
		width: 100%;
		height: 100%;
		line-height: 90px;
		text-align: center;
		background: rgba(255, 255, 255, 0.3);
	}

	#time_body {
		margin: auto;
		position: absolute;
		top: 0;
		bottom: 0;
		right: 0;
		left: 0;
		height: 50%;
		width: 90%;
	}

	.time {
		font-size: 90px;
	}

	.title {
		font-size: 40px;
		margin-bottom: 60px;
	}

	li {
		float: left;
		width: 30%;
		list-style: none;
	}
</style>

2、body引入HTML代码

<div id="container">
	<div id="time_body">
		<ul>
			<li id="beijing" class="time"></li>
			<li id="mengmai" class="time"></li>
			<li id="niuyue" class="time"></li>
			<li class="title">北京时间</li>
			<li class="title">孟买时间</li>
			<li class="title">纽约时间</li>
			<li id="dongjing" class="time"></li>
			<li id="bali" class="time"></li>
			<li id="xini" class="time"></li>
			<li class="title">东京时间</li>
			<li class="title">巴黎时间</li>
			<li class="title">悉尼时间</li>
		</ul>
	</div>
</div>


<script type="text/javascript">
    function startTime() {
        document.getElementById('beijing').innerHTML = calcTime(+8)
        document.getElementById('mengmai').innerHTML = calcTime(+5.5)
        document.getElementById('niuyue').innerHTML = calcTime(-5)
        document.getElementById('dongjing').innerHTML = calcTime(+9)
        document.getElementById('bali').innerHTML = calcTime(+2)
        document.getElementById('xini').innerHTML = calcTime(+10)
        t = setTimeout('startTime()', 1000)
    }

    function checkTime(i) {
        if (i < 10) { i = "0" + i }
        return i
    }

    function calcTime(offset) {
        var d = new Date();
        var utc = d.getTime() + (d.getTimezoneOffset() * 60000);
        var nd = new Date(utc + (3600000 * offset));
        var h = nd.getHours()
        var m = nd.getMinutes()
        var s = nd.getSeconds()
        h = checkTime(h)
        m = checkTime(m)
        s = checkTime(s)
        return h + ":" + m + ":" + s
    }


</script>

3、body默认函数调用

onLoad="startTime()
