The display is controlled by an Atmel ATMega328P-AU MCU with Arduino code, and the time is kept by a Maxim DS3231 Real-Time Clock module, that stays connected to the LiPo battery at all times, keeping time even when the microcontroller and display are not powered.

RafaelRiber shared the board on OSH Park:
