Arduino interface to Real Time Clock (RTC?)

Is the real-time clock readable by the ATMEGA32U4 microcontroller? Is there an i2c address or other interface for it? It would be useful to be able to read the RTC from the uC in order to program wake / shutdown of the main processor according to a schedule.
