我猜这就是大多数人想要的:

微软时区索引值

希望微软即使在XP之后也能保持更新。

下面是微软提供的时区列表

时区标识符列表，默认包含在Windows XP和Vista中:查找本地系统上定义的时区

var timeZoneInfos = TimeZoneInfo.GetSystemTimeZones();

上面给出了一个时区列表，其中包括id。

这里是我从nimrod教授的答案转换而来的Json版本…

这是c#中的SelectListItem (asp .net)

你可以在后台写代码:

public static List<SelectListItem> GetTimezoneList()
{
    try
    {
        // list of timezone
        List<SelectListItem> timezoneList = new List<SelectListItem>();

        timezoneList.Add(new SelectListItem() { Value = "", Text = "Select TimeZone...", Selected = false });
                
        var timezoneInfo = TimeZoneInfo.GetSystemTimeZones();
                
        foreach (var item in timezoneInfo)
        {
            timezoneList.Add(new SelectListItem() 
            {
                Value = item.StandardName, Text = item.DisplayName, Selected = false });
            }
            return timezoneList;
        }
    }
    catch (Exception e)
    {
        throw e;
    }
}

在前端

@Html.DropDownListFor(s => s.TimeZone, YourbackendServiceName.GetTimezoneList(), new { @class = "form-control input-md" })

这将给你所有的时区DisplayName…即印度标准时间 下拉列表
