            return ret;

    }

1.游戏启动，请求到服务器时间  
可能各个语言的DateTime 的时间格式对不上，这里就先手动string转C\#的datatime

SyncTime.Sync(SyncTime.Server2Stamp(ret.time));

2.当前服务器时间：时间戳格式

long curServerTime = SyncTime.DateTime2Stamp(SyncTime.GetSystemTime());

3.得到当前服务器时间距离截止时间戳的剩余时间

TimeSpan left = SyncTime.GetLeftTime(m_endTime);
