A project log for Rubidium Disciplined Real Time Clock

A Time Travel Beacon

An arduino knock-off compares the relative delay between the pulse-per-second outputs from the RTC and the Rubidium standard. After some defined time divergence, the aging compensation register is updated to refine or maintain their overall agreement. Essentially herding the RTC so that its output stays within bounded agreement with the Rubidium standard.

This approach avoids editing the time registers directly, eliminating the possibility of corrupted writes.
