   * This override for covering both GSM and CDMA modem message format

   * For GSM modem, send time field can be found in AT+CMGL. But it can't be
   * found for CDMA modem
   *
   * GSM modem +CMGL: 2,"REC READ","+8613520073322",,"08/07/02,15:10:49+32"
   * GSM Hello,World
   *
   *
   * For CDMA modem, The message format like below. +CMGL:6,"REC
   * UNREAD","13911577644",0,2,23 Just for test send time
   *
   * when the message read by the index, the time is displayed, like this:
   * AT+CMGR=6 +CMGR:"REC UNREAD","13911577644","08/07/09,11 :41 :49",0,2,3,23
   * Just for test send time OK
   *
   * So overwrite this method to cover this case
