Blynk libraries cant seem to be read by arduino IDE

Need Help With My Project
1

Good day, I connected push buttons to nodeMCU. Supposedly, the data should be seen on terminal widget of the blynk app. I can’t compile the code. the arduino IDE cant seem to read the blynk libraries. I will be using Blynk 1.3.12 on android.

Code:
    #define BLYNK_PRINT Serial
#define SimpleTimer BlynkTimer 
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <WidgetRTC.h>
#include <SimpleTimer.h>
#include <TimeLib.h>

#define BLYNK_TEMPLATE_ID           "TMPLxxxxxx" 
#define BLYNK_DEVICE_NAME           "Device" 
#define BLYNK_AUTH_TOKEN            "YourAuthToken"

const int button1Pin = D3;
const int button2Pin = D4;
const int button3Pin = D7;
const int button4Pin = D8;

class SimpleTimer timer;
char auth[] = "xxxxxxxxxxxxx";
char ssid[] = "xxxxxxxxxxx";
char pass[] = "xxxxxxxxxxx";
const int timeZone = 8; 

WidgetRTC rtc; 
WidgetTerminal terminal(V0);
BLYNK_ATTACH_WIDGET(rtc, V0);
// You can send commands from Terminal to your hardware. Just use
// the same Virtual Pin as your Terminal Widget
BLYNK_WRITE(V0)
{
  int pinValue = param.asInt();
   String currentTime = String(hour()) + ":" + minute() + ":" + second();
    String currentDate = String(day()) + "/" + month() + "/" + year();
      
 terminal.print("OTC No:");
 terminal.print(pinValue);
 terminal.print(" Dispense time ");
 terminal.print(currentTime);
 terminal.print("hrs del");
 terminal.print(currentDate);
 terminal.println("");
 terminal.println("");
    terminal.flush();
}

BLYNK_CONNECTED() {
  Blynk.syncAll();
}
void setup()
{
Serial.begin(9600);
 Blynk.begin(auth, ssid, pass);
 pinMode(button1Pin, INPUT);
 pinMode(button2Pin, INPUT);
 pinMode(button3Pin, INPUT);
 pinMode(button4Pin, INPUT);
 while (Blynk.connect() == false) {
    // Wait until connected
  }
  terminal.println(F("Blynk v" BLYNK_VERSION ": Device started"));
  terminal.println("-------------");
  terminal.flush();
  rtc.begin();
}

void loop(){
 Blynk.run();
    timer.run();
delay(1000);
}

These are the errors:

please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly. Triple backticks look like this: ```

Is that a typo?

To be honest, your code is a total mess, and its difficult to know where to start when it comes to putting it right. I assume that it’s either written by someone else, or is some sort of Frankenstein copy/paste job?

Knowing whether you are using Blynk Legacy or Blynk IoT would be a good start, and your app version should tell us that - except that the version number you’ve provided makes no sense.
Knowing which Blynk library version you are using would also be useful.
