I have made a clock with DS1307 + atmel. The major problem is time accuracy, the time on display was very fast (20 second advance in a minute), I tried my best to solve the problem, then when I put 104 capacitor on the supply pin, it bacme controlled but still in one one hour it is 2 second advanced. I want it 99.99% accurate but dont know how to do it? I m using 32 kHz crystal. Please sugget me how to get my goal???? Plz give me some useful points, plz dont tell me to change the crystal as not availble in market.
also tell me how to calebrate the clock to get 100% result (accuracy).
regards.
