This was the output for the complete strings. I showed both versions, substring and complete string. As you mention if even substrings do not match, there's no difference. The latest code is below. I have only removed the substring that's all. 22:15:20 for RTC and 22:15:20 for input from keypad. The 0 is the result for comparison.

#include <Keypad.h>
#include <DS1302.h>
#include <Servo.h>

const byte ROWS = 4; //four rows
const byte COLS = 4; //four columns
 
//define the cymbols on the buttons of the keypads
char hexaKeys[ROWS][COLS] = {
  {'A','3','2','1'},
  {'B','6','5','4'},
  {'C','9','8','7'},
  {'D','#','0',':'}
};
 
byte rowPins[ROWS] = {10, 11, 12, 13}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {6, 7, 8, 9}; //connect to the column pinouts of the keypad
char key;
String feedTime;
boolean feed = true; // condition for alarm
char t1, t2, t3, t4, t5, t6;


//initialize an instance of class NewKeypad
Keypad customKeypad = Keypad( makeKeymap(hexaKeys), rowPins, colPins, ROWS, COLS);
// Init the DS1302
DS1302 rtc(4, 3, 5);
Servo servo_test;      //initialize a servo object for the connected servo  
int c = 0;

  servo_test.attach(2);   // attach the signal pin of servo to pin9 of arduino
  // Set the clock to run-mode, and disable the write protection
  rtc.halt(false);
