DS3231 Real Time Clock on a Raspberry Pi with Ubuntu Xenial

By this point I really don’t need to explain how great the Raspberry Pi is - a nice useful lump of computing power for not very much money1 . The low price point does mean that you loose some features that come standard on larger computers though, and one of the less obvious omissions is a ‘real time clock’ module to keep track of time while the main computer is powered off.
