<!--要完成此效果需要三个步骤
第一步：把如下代码加入到<head>区域中-->
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function isodatetime() {
var today = new Date();
var year = today.getYear();
if (year < 2000)
year = year + 1900;
var month = today.getMonth() + 1;
var day = today.getDate();
var hour = today.getHours();
var hourUTC = today.getUTCHours();
var diff = hour - hourUTC;
var hourdifference = Math.abs(diff);
var minute = today.getMinutes();
var minuteUTC = today.getUTCMinutes();
var minutedifference;
var second = today.getSeconds();
var timezone;
if (minute != minuteUTC && minuteUTC < 30 && diff < 0) { hourdifference--; }
if (minute != minuteUTC && minuteUTC > 30 && diff > 0) { hourdifference--; }
if (minute != minuteUTC) {
minutedifference = ":30";
}
else {
minutedifference = ":00";
}
if (hourdifference < 10) {
timezone = "0" + hourdifference + minutedifference;
}
else {
timezone = "" + hourdifference + minutedifference;
}
if (diff < 0) {
timezone = "-" + timezone;
}
else {
timezone = "+" + timezone;
}
if (month <= 9) month = "0" + month;
if (day <= 9) day = "0" + day;
if (hour <= 9) hour = "0" + hour;
if (minute <= 9) minute = "0" + minute;
if (second <= 9) second = "0" + second;
time = year + "-" + month + "-" + day + "T"
+ hour + ":" + minute + ":" + second + timezone;
document.isoclock.display.value = time;
window.setTimeout("isodatetime();", 500);
}
// End -->
</script>
<!--第二步：把如下代码加入到<body>区域中-->
<center>
<form name=isoclock>
<input type=text name=display size=30 style="border:0;">
</form>
</center>
<!--第三步：把“OnLoad="isodatetime()"”加在<body>标记里
例如：-->
<body OnLoad="isodatetime()">
