c# - 如何以编程方式加快系统时间？

Question

我需要通过为每个（例如）200 毫秒添加随机秒数来加快 PC 系统时间。我试图通过以编程方式查看更改系统日期线程来解决这个问题。

using System;
using System.Runtime.InteropServices;
using System.Threading;

namespace TimeSpeedUp
{
    struct SystemTime
    {
        public ushort Year;
        public ushort Month;
        public ushort DayOfWeek;
        public ushort Day;
        public ushort Hour;
        public ushort Minute;
        public ushort Second;
        public ushort Millisecond;
    }
    class Program
    {
        [DllImport("kernel32.dll", EntryPoint = "GetSystemTime", SetLastError = true)]
        public extern static void Win32GetSystemTime(ref SystemTime sysTime);

        [DllImport("kernel32.dll", EntryPoint = "SetSystemTime", SetLastError = true)]
        public extern static bool Win32SetSystemTime(ref SystemTime sysTime);
        public static Random Random = new Random();

        static void Main(string[] args)
        {
            Timer timer = new Timer(SetTime);
            timer.Change(0, 200);
            while (true)
            {
                ConsoleKeyInfo keyInfo = Console.ReadKey(true);
                if (keyInfo.Key == ConsoleKey.Escape)
                {
                    break;
                }
            }
        }

        public static void SetTime(object obj)
        {
            // Current time
            SystemTime currentTime = new SystemTime();
            Win32GetSystemTime(ref currentTime);
            // Set system date and time
            SystemTime updatedTime = new SystemTime();
            updatedTime.Year = (ushort)currentTime.Year;
            updatedTime.Month = (ushort)currentTime.Month;
            updatedTime.Day = (ushort)currentTime.Day;
            updatedTime.Hour = (ushort)currentTime.Hour;
            updatedTime.Minute = (ushort)currentTime.Minute;
            updatedTime.Second = (ushort)(currentTime.Second + Random.Next(1, 3));
            // Call the unmanaged function that sets the new date and time instantly
            Win32SetSystemTime(ref updatedTime);
        }
    }
}

应用程序无法更改系统日期，因为它没有管理权限。以管理员身份运行应用程序可以解决问题。
