warmbell My clock gained about 12 minutes a day after trying to find a fix I tried placeing a 22pf capacitor accross C4 and C5 in turn, found that c4 was open circiut. I replaced it with a 40pf trimmer and now find I can make small adjustments to the timing. If there is a future version of this clock it would be a good idea to add a TXCO IC which gives a stable 32768 Hz output to the RTC IC.
