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

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。

从MSDN

ReadOnlyCollection<TimeZoneInfo> zones = TimeZoneInfo.GetSystemTimeZones();
Console.WriteLine("The local system has the following {0} time zones", zones.Count);
foreach (TimeZoneInfo zone in zones)
   Console.WriteLine(zone.Id);

这是你要找的链接:

c#系统时区id

下面是一个程序及其结果的完整列表。

代码:

using System;

namespace TimeZoneIds
{
    class Program
    {
        static void Main(string[] args)
        {
            foreach (TimeZoneInfo z in TimeZoneInfo.GetSystemTimeZones())
            {
                // For a Console App
                Console.WriteLine(z.Id + "," + z.BaseUtcOffset + "," + z.StandardName + "," + z.DisplayName + "," + z.DaylightName);
                // For any other App
                System.Diagnostics.Debug.WriteLine(z.Id + "," + z.BaseUtcOffset + "," + z.StandardName + "," + z.DisplayName + "," + z.DaylightName);
            }
        }
    }
}

结果会随着时间而改变:

DateTime dt;
TimeZoneInfo tzf;
tzf = TimeZoneInfo.FindSystemTimeZoneById("TimeZone String");
dt = TimeZoneInfo.ConvertTime(DateTime.Now, tzf);
lbltime.Text = dt.ToString();
