12 hour LED clock

04:31:10

What's the difference in this clock! It handle the time properly.
AM11:59 -> PM12:00
PM11:59 -> AM00:00
It use one button to set the time when the period is on.
The period turn on 12 seconds and turn off 3 seconds for each digit.
AM/PM indicator on the leftmost segments.
One disadvantage in EC is the unwanted digit is showed when the counter reset, 0 -> A -> 9. I can get rid of this by using synchronize logic,but it required some more gates.
