現在の時刻を文字列に

C++
　time_t tim_v = ::time(NULL) ;
　struct stm = ::localtime(&tim_v) ;
　tstring buff ;
　size_t size = 255 ;
　buff.resize(size+1,0) ;
　::_tcsftime(&buff[0],size,_T("%Y/%m/%d %H:%M:%S"),&stm) ;
　tstring str = buff.c_str() ;

MFC
　CString str = CTime::GetCurrentTime().Format(_T("%Y/%m/%d %H:%M:%S")) ;

JavaScript
　var time = new Date() ;
　var y_ = time.getFullYear() ;
　var m_ = time.getMonth() + 1 ;
　var d_ = time.getDate() ;
　var hh = time.getHours() ;
　var mm = time.getMinutes() ;
　var ss = time.getSeconds() ;
　var str= (y_+"/"+m_+"/"+d_+" "+hh+":"+mm+":"+ss) ;

PHP
　date_default_timezone_set('Asia/Tokyo') ;
　$str = date("Y/m/d H:i:s") ;
