如何用JS做出不同国家的时间代码？
这样（原创，请保留作者信息）：
/**
* 根据时区获取相应的时间
* @author hutia
* @param {Date} date 日期时间对象
* @param {number} timezone 时区
* @return {string} 返回时间字符串
*/
function getTimeString(date, timezone){
var tz = date.getTimezoneOffset();
var dt = new Date();
dt.setTime(date.getTime() + tz*60000 + timezone*3600000);
return format(dt.getHours()) + ':' + format(dt.getMinutes()) + ':' + format(dt.getSeconds());
function format(n) {
if (n 10) return '0' + n;
return ''+n;
}
}
// 下面是使用示例
var now = new Date();
document.write('北京 ' + getTimeString(now, 8) + 'br/');
document.write('伦敦 ' + getTimeString(now, 0) + 'br/');
document.write('纽约 ' + getTimeString(now, -5) + 'br/');
document.write('东京 ' + getTimeString(now, 9) + 'br/');
使用后会输出：
北京 08:44:48
伦敦 00:44:48
纽约 19:44:48
东京 09:44:48
以上，请采纳，请给分。

求JS代码显示北京时间和洛杉矶时间，
洛杉矶时区是西八区，代码：
var sq=-8; //设置时区，东为正数，西为负数
var d = new Date();
var utc = d.getTime() + (d.getTimezoneOffset() * 60000);
var nd = new Date(utc + (3600000*sq));
alert("北京时间："+d.toLocaleString()+"rr洛杉矶时间："+nd.toLocaleString());

JS如何获取北京时间
参考代码如下：
SCRIPT LANGUAGE = "JavaScript"
var xmlhttp = new ActiveXObject("MSXML2.XMLHTTP.3.0");
xmlhttp.open("GET", "", false);
xmlhttp.setRequestHeader("If-Modified-Since", "bjtime");
xmlhttp.send();
var dateStr = xmlhttp.getResponseHeader("Date");
var date = new Date(dateStr);
var year = date.getFullYear();
var month = date.getMonth() + 1;
var date1 = date.getDate();
var hour = date.getHours();
var minutes = date.getMinutes();
var second = date.getSeconds();
alert(date + " | " + year + "年" + month + "月" + date1 + "日" + hour + "时" + minutes + "分" + second + "秒");
/SCRIPT
