RTCZero | Arduino Documentation
This library allows an enables an Arduino based on SAMD architectures (es. Zero, MKRZero or MKR1000 Board) to control and use the internal RTC (Real Time Clock). A real-time clock is a clock that keeps track of the current time and that can be used in order to program actions at a certain time.

RTC RV-3028-C7 Arduino Library - Arduino Reference
A library to drive the RV-3028-C7 extremely precise, extremely low power, real-time clock The RV-3028-C7 is an extremely precise, extremely low power, highly configurable RTC. Under ideal conditions it runs at approximately 40nA with +/-5ppm per year of deviation (+/- 160 seconds worst case per year). This library was originally forked from the Sparkfun RV-1805 library, and costumized and enhanced to the RV-3028-C7. ... This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
