The battery-backed real time clock (RTC) from Adafruit allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC chip, and works best with 5V-based chips such as the Arduino or Raspberry Pi!
