C#DateTime.Now取得本地时间不对

替换方法

改用windowsAPI获取

       [DllImport("kernel32.dll", EntryPoint = "GetSystemTime", SetLastError = true)]
        internal static extern void GetSystemTime(out SYSTEMTIME st);
        [DllImport("kernel32.dll", EntryPoint = "GetLocalTime", SetLastError = true)]
        internal static extern void GetLocalTime(out SYSTEMTIME st);

          /// <summary>
        /// 获取时间戳
        /// </summary>
        /// <returns></returns>
        public static DateTime Now()
        {
            try
            {
                SYSTEMTIME time;
                TimeHelper.GetLocalTime(out time);
                DateTime now = new DateTime(time.wYear, time.wMonth, time.wDay, time.wHour, time.wMinute, time.wSecond);
                return now;
            }
            catch
            {
                return DateTime.Now;
            }
           
        }

        [StructLayout(LayoutKind.Sequential)]
        public struct SYSTEMTIME
        {
            public short wYear;
