DS1307 RTC is interface using I2C interface.
you have set time and then start the clock..
later u can read the time

here is program which sets time and reads time using PC interface MAX232..
on hyperterminal

here u can find datasheet

To see what you do you will need some sort of display ..
Here is a project that uses PC as display and kbd ..
