Project: ITDB02 Analog Clock has been replaced with the updated version Project: UTFT Analog Clock. It is basically the same except that it has been updated to use the newer libraries and this version also has a serial mode to set the clock.
As the currect version of ITeads ITDB02 Mega shield no longer has an on-board DS1307 I highly recommend that you take a look at the Arduino Mega / Chipkit MAX32 Screw Shield with TFT and RTC from AquaLEDsource for a "easy-to-use" shield for this project. Links to their English and Portuguese webshops can also be found on the Links page.
