another fun "we had a better solution in the past!" is using the 60hz AC sine wave as a time signal. The timebase is actually corrected for this use-case! there is absolutely no reason to use a piezo timer in any circuit that is plugged in to AC and the drift that typically occurs with piezos is so frustrating. https://en.wikipedia.org/wiki/Utility_frequency#Time_error_correction_(TEC) https://en.wikipedia.org/wiki/Utility_frequency#Time_error_c...
