DS3231 Real time clock (RTC)

The Pi keeps such bad time, I've had bad results trying to monitor a hive without the internet and NTP servers to keep the Pi's clock correct. I haven't tested this with the hive interface board plugged in - that may take a bit of a kludge or longer (stackable) header pins, but the DS3231 RTC works with the 0.7.4 image.
I ordered a " SunFounder DS3231 RTC Real Time Clock Module High Precision for Raspberry Pi
Arduino R3 Mega 2560" for $8.99 from

I accidentally followed these instructions for a DS1307 RTC, but it worked flawlessly:
