[SOLVED] How to get live GPS Sim800 Module RTC time on Arduino

Hello I wanted the live GPS Sim800 Module RTC time on Arduino without the use of library, I am able to achieve it using library but without library the correct data comes in only 1 minute and other comes the garbage.

Please tell me the code that can help me achieve it

Using code I did the following thing

#include <SoftwareSerial.h>
SoftwareSerial gsm(10, 11);
String Buffer;
String inData;

int i;
int *year, *month, *day, *hour, *minute, *second;

void setup() {
  Serial.begin(9600);
  gsm.begin(9600);
  delay(5000);
}

void loop() {
Ansh:
  delay(500);
  gsm.println("AT+CCLK?\r\n");
  while (gsm.available()) {
    char recieved = gsm.read();
    inData += recieved;
    delay(100);

    // Process message when new line character is recieved
    if (recieved == '\n')
    {
      Serial.print("Arduino Received: ");
      Serial.println(inData);

      if (inData.substring(1, 5) == "+CCLK") {
        Serial.println("Hello");
      }

      // You can put some if and else here to process the message juste like that:

      if (inData == "+++\n") { // DON'T forget to add "\n" at the end of the string.
        Serial.println("OK. Press h for help.");
      }


      inData = ""; // Clear recieved buffer
      goto Ansh;
    }

    /* Buffer = Buffer.substring(Buffer.indexOf("\"") + 1, Buffer.lastIndexOf("\"") - 1);
      year = Buffer.substring(0, 2).toInt();
      month = Buffer.substring(3, 5).toInt();
      day = Buffer.substring(6, 8).toInt();
      hour = Buffer.substring(9, 11).toInt();
      minute = Buffer.substring(15, 17).toInt();
      second = Buffer.substring(18, 20).toInt();
    */
  }/*
  Serial.println(*hour);
  delay(100);
  Serial.println(*minute);
  delay(100);
  Serial.println(*second);
  delay(100);
*/
}

But I don't get live output but after 1 correct output it returns garbage as follows

if I remove the delays from the code then I receive the following output
