Arduino code for LCD based Digital clock_Time initialization using keypad

Hi,
The following code written for LCD based hourly Alarm Digital clock.
Here, the current time is initialised in the program itself. But i want to know how can we initialise the time from keypad.
Can anyone please suggest me?? You may contact me at sunilkumar.vemuri@gmail.com

Thanku.

#include <Keypad.h>
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(8, 9, 10, 11, 12, 13);//RS,EN,D4,D5,D6,D7
const byte ROWS = 4; // Four rows
const byte COLS = 4; // Three columns
// Define the Keymap
char keys[ROWS][COLS] = {
{‘1’,‘2’,‘3’,‘A’},
{‘4’,‘5’,‘6’,‘B’},
{‘7’,‘8’,‘9’,‘C’},
{’*’,‘0’,’#’,‘D’}
};
// Connect keypad ROW0, ROW1, ROW2 and ROW3 to these Arduino pins.
byte rowPins[ROWS] = { 0, 1, 2, 3 };
// Connect keypad COL0, COL1 and COL2 to these Arduino pins.
byte colPins[COLS] = { 4, 5, 6, 7 };
// Create the Keypad
Keypad kpd = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
int k,hi=22,mi=24,si=45,h,m,s,s1,s2,m1,m2,h1,h2;

{
pinMode(k,OUTPUT);//pins 8-14 are enabled as output
}
lcd.begin(16, 2);//initializing LCD
pinMode(buzz, OUTPUT);
}
void loop()
