获得系统时间

 

　　在C中(VS2005中会出现warning C4996)：

                        time ( &rawtime );

                        timeinfo = localtime ( &rawtime );

                        char logfilename[50];

                        sprintf( logfilename, "%04d%02d%02d.log",timeinfo->tm_year+1900,timeinfo->tm_mon+1,timeinfo->tm_mday);
