I replied in another thread a couple weeks ago about my work with the MCP79412, so I hope the mods don't consider this a cross-post...
I recently pushed v1.0 of the library as well as the PCB to github, and wrote it up on my blog.
Comments welcome. Is there room out there for Yet Another RTC?
What is the advantage of this method of adjusting/calibrating compared to doing it in C code?

No C code I guess XD
Obviously some method of determining the required adjustment is needed, and that may require C code, but once that is done, the RTC adjusts itself continually.
