You need to learn Microcontrollers to do that. Arduino is a good example, but may be expensive depending of your country.

Another option. A bit of Internet searching comes up with this part. This single IC digital clock appears to be produced presently and distributed. Asian part apparently. I remember the old Mostek IC, but those are long gone.
