Improved digital clock

I've updated my almost silent digital clocks. There seems to be an issue with the digital counter in my last design, that would occassionally make it malfunction. I completely redisigned the entire clock. The new design fixed the problem and made several improvements. The number change is smoother, faster, and synchronized. I was able to make a 24 hour version, a 24 hr with seconds counter, and a 12 hr version with am/pm indication, and supremely compact slim version! Below each number is a reset to 0 button (or 1 for the hour place on 12 hr) and an add 1 button, for convenience while setting the time. Around back towards the middle, there's a switch that disables and resets the time keeping clock. Turn it off while setting time to prevent malfunction. Enjoy!
