Javascript Date函数在不同的操作系统中返回不同的时区，如在mac系统中返回“India standard time”windows操作系统和“IST” . 我希望在所有操作系统中都是“印度标准时间” .

这是我的代码：

<!DOCTYPE html>
<html>
<body>

<p id="demo"></p>

<script>
document.getElementById("demo").innerHTML = Date();
</script>

</body>
</html>

结果在Windows中：Tue Feb 14 2017 13:03:02 GMT 0530（印度标准时间）在mac系统：2017年2月14日星期二13:03:02 GMT 0530（IST）

    已经在问题评论中提到了 .

    Object.defineProperty(Date.prototype, "getTimezoneString", {
    enumerable: false,
    writable: true,
    configurable: false,
    value: function(){
    	var retval = "Z";
			var offset = this.getTimezoneOffset() / 60;
			switch (offset) {
      	case 14: retval = "M†"; break;
      	case 13.75: retval = ""; break;
      	case 13: retval = "M†"; break;
      	case 12.75: retval = "M"; break;
      	case 12: retval = "M"; break;
      	case 11: retval = "L"; break;
      	case 10.5: retval = "K†"; break;
      	case 10: retval = "K"; break;

var timezone = new Date().getTimezoneString();
document.querySelector("#date").innerHTML = timezone;

    我建议你使用时刻js . 如果您正在使用amd模块加载器，那么您可以执行以下操作：

    require(["moment"],(m)=>{console.log(m().utcOffset(330).format())})

    <script>
    var currentTime = new Date(),
    hours = currentTime.getHours(),
    minutes = currentTime.getMinutes();

    if (minutes < 10) {
        minutes = "0" + minutes;
    }

    document.write(hours + ":" + minutes)
</script>
