oled lcd 128*32 orologio senza modulo rtc

Buongiorno,
sto provano da tempo a compilare questo sketch ma non riesco a concluderlo.
riuscireste ad aiutarmi grazie mille.

#include <SPI.h>
#include <Wire.h>

#include <Adafruit_SSD1306.h>

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 32 // OLED display height, in pixels

// Declaration for an SSD1306 display connected to I2C (SDA, SCL pins)
#define OLED_RESET 4 // Reset pin # (or -1 if sharing Arduino reset pin)
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

int s;
int flag;
int TIME;

const int hs=8;

#define NUMFLAKES 10 // Number of snowflakes in the animation example

void setup() {
if(!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) { // Address 0x3C for 128x32
Serial.println(F(“SSD1306 allocation failed”));
for(;;); // Don’t proceed, loop forever
}
// Show initial display buffer contents on the screen –
// the library initializes this with an Adafruit splash screen.
display.display();
// Clear the buffer
display.clearDisplay();
