/**
* \brief Attaches to a realtime clock slave device on \a bus.
*
* If \a oneHzPin is not 255, then it indicates a digital input pin
* that is connected to the 1 Hz square wave output on the realtime clock.
* This input is used by hasUpdates() to determine if the time information
* has changed in a non-trivial manner.
*
* If you wish to use enableAlarmInterrupts(), then \a oneHzPin must be 255.
