I thought that that LCD pin configuration is too good to be true but, if you are getting anything at all, I guess it has to be kosher.
The code you are using is very much the same as I use for all my clocks. That below sends time to serial as well as LCD and might have what you want.
//Arduino 1.0+ Only
//Arduino 1.0+ Only
#include <LiquidCrystal.h>

void setup(){
Wire.begin();
Serial.begin(9600);
lcd.begin(16, 2);
lcd.clear();
// Print a message to the LCD.
lcd.print("It is");
}
void loop(){
printDate();
delay(1000);
}
byte bcdToDec(byte val) {
// Convert binary coded decimal to normal decimal numbers
return ( (val/16*10) + (val%16) );
}
void printDate(){
// Reset the register pointer
Wire.beginTransmission(DS1307_ADDRESS);
byte zero = 0x00;
Wire.write(zero);
Wire.endTransmission();
Wire.requestFrom(DS1307_ADDRESS, 7);
int second = bcdToDec(Wire.read());
int minute = bcdToDec(Wire.read());
int hour = bcdToDec(Wire.read() & 0b111111); //24 hour time
int weekDay = bcdToDec(Wire.read()); //0-6 -> sunday - Saturday
int monthDay = bcdToDec(Wire.read());
int month = bcdToDec(Wire.read());
int year = bcdToDec(Wire.read());
lcd.setCursor(2, 1);
switch (weekDay) // Friendly printout the weekday
