最近开发时遇到PDA访问服务器时要和设置服务器的时间到PDA(C#中修改系统时间可不如C++方便)，参考了http://blog.csdn.net/iorikyo/archive/2006/10/01/1314892.aspx的文章后通过下面这个类解决了修改PDA时间的问题。代码如下：

using System;
using System.Runtime.InteropServices;

namespace setlocaltime
{
    class Systemtime
    {
        [DllImport("coredll.dll")]
        public static extern bool SetLocalTime(ref SYSTEMTIME Time);
        [DllImport("coredll.dll")]
        public static extern void GetLocalTime(ref SYSTEMTIME Time);
    }
    public struct SYSTEMTIME
    {
        public ushort wYear;
        public ushort wMonth;
        public ushort wDayOfWeek;
        public ushort wDay;
        public ushort wHour;
        public ushort wMinute;
        public ushort wSecond;
        public ushort wMilliseconds;

        /// <summary>
        /// 从System.DateTime转换。
        /// </summary>
        /// <param name="time">System.DateTime类型的时间。</param>
        public void FromDateTime(DateTime time)
        {
            wYear = (ushort)time.Year;
            wMonth = (ushort)time.Month;
            wDayOfWeek = (ushort)time.DayOfWeek;
            wDay = (ushort)time.Day;
            wHour = (ushort)time.Hour;
            wMinute = (ushort)time.Minute;
            wSecond = (ushort)time.Second;
            wMilliseconds = (ushort)time.Millisecond;
        }
        /// <summary>
        /// 转换为System.DateTime类型。
        /// </summary>
        /// <returns></returns>
        public DateTime ToDateTime()
        {
            return new DateTime(wYear, wMonth, wDay, wHour, wMinute, wSecond, wMilliseconds);
        }
        /// <summary>
        /// 静态方法。转换为System.DateTime类型。
        /// </summary>
        /// <param name="time">SYSTEMTIME类型的时间。</param>
        /// <returns></returns>
        public static DateTime ToDateTime(SYSTEMTIME time)
        {
            return time.ToDateTime();
        }

}
}
