I finished writing a library to use a DS1307 realtime clock in an Arduino. The library is available on my Arduino libraries page: http://isomk.sdf.org/arduino.html
12 hour time modes are sketchy at best since I never use them. If there is interest in 12 hour support, email me at brokenlcd .:[ at ]:. google’s email service
Video of the interface using a 16x2 LCD and thumbstick will be available soon, along with a sketch showing an example interface using my arduino development board:
