  // Please see Time library examples for details

  String currentTime = String(hour()) + ":" + minute() + ":" + second();
  String currentDate = String(day()) + " " + month() + " " + year();
  Serial.print("Current time: ");
  Serial.print(currentTime);
  Serial.print(" ");

  // Send date to the App
  Blynk.virtualWrite(V2, currentDate);
}

You’re declaring the variable menit as a local variable when you put “long” in front of it in this function. That means that the scope of the variable is limited to just that function.

Declare it as a long variable type at the top of your code and it will be available globally within all of your code.
