Well, to be fair I modified a library.

Micro Crystal has a new chip out, the RV-3032-C7 that beats the Maxim DS3231 in basically every way. It's more accurate, lower power, takes a wider voltage range, is smaller, the list goes on. I got my demo board from them a couple days ago and have been very impressed.

I have been tooling around with Sparkfun's RV-8803 library and have managed to get nearly everything working on this new RTC. Check out the Github repo!
