Based on the computer system LCARS from the Star Trek series.
The numbers under the current time "1701" will show the time in UNIX timestamp.
The bars at the bottom will show the time like 'Times Square' or possibly in binary.
Updated with simple animation

It now shows the current unix epoch for GMT +1
If you want it for your timezone you need to change the GMT offset and rebuild the face.
