any DS1307 chip can use, just define correct I2C bus pins is ok.

I think I found the solution, se below.
// Set i2c for RTC DS1307
#define SDA:4
#define SCL:5
or
// Set i2c for RTC DS1307
#define IIC SDA:4
#define IIC SCL:5
or
// Set i2c for RTC DS1307
#define i2c SDA:4
#define i2c SCL:5
Which one is the correct one???

IIC SDA:4
IIC SCL:5
you should set it in your arduino "pins_arduino.h" file set SDA and SCL pins.
