Problem with RTC and time library

Projects Programming

Thank you very much for the quick respond
The libraries I have downloaded from there: DS1307RTC Library, For Accessing Real Time Clock (RTC) Chips.
Since I am just experimenting, I use very basic code:

#include <DS1307RTC.h>
#include <Time.h>
#include <Wire.h>

void setup() {
  Serial.begin(9600);
}

void loop() {
     tmElements_t tm;               
     if(RTC.read(tm)) {             
       currentHour = tm.Hour;       
       currentMinute = tm.Minute;   
       currentDay = tm.Wday;
    }
    Serial.print("Current day: ");
    Serial.println(currentDay);
    Serial.print("Current Time: ");
    Serial.print(currentHour);
    Serial.print(" : ");
    Serial.println(currentMinute);
}

Thanks again for having a look at
