RTClib is a lightweight date and time library for JeeNodes and Arduino's.
Work in progress - see this discussion for some background info.
This library has also been forked at https://github.com/adafruit/RTClib.
The latest source code for this project is maintained on GitHub.
- Unpack the archive and rename the resulting folder to "RTClib".
- Move it to the "libraries" folder in your Arduino sketches area.
- Restart the Arduino IDE to make sure it sees the new files.
The wiki for this library is at http://jeelabs.net/projects/cafe/wiki.
The API documentation is generated by Doxygen and can be found here.
