Real Time Clock with Nucleo-64 board

I am using an ST Nucleo-64 (STM32F401) board. I have an application where I need the current time in Unix time (seconds after 1/1/1970).

Is there a way to have a real time clock with a battery backup so that I don’t have to re-enter the current time and compile every time i power the board off?

Thanks
