Connections for Standard 32.768kHz Quartz Crystal. The internal oscillator is
designed for operation with a crystal having a specified load capacitance of...
Fixed, it was crystal issue. I've bought expensive, 6pf matched crystals from digikey, but they did not worked with DS1302. Installed some cheap one from China - works fine :D
My programming skills are quite limited, even with DS1302, it took me almost month to make things going :) I've bought DS3231, but no luck with it so far :(

Board layout is very critical around the Xtal. Datasheet recommendations should be taken very seriously into account.
