Harvey the hacker hacked my clock. At first, the results made no sense, but I eventually figured out his logic.
At 12:00, the clock shows 12:19
At 12:01, the clock shows 12:15
At 12:02, the clock shows 12:18
At 12:03, the clock shows 12:18
At 12:04, the clock shows 12:17
At 12:05, the clock shows 12:18
At 12:06, the clock shows 12:19
At 12:07, the clock shows 12:16
At 12:08, the clock shows 12:20
At 12:09, what will the clock show, and why?

At 12:09 the clock should display
12:19, as the minutes count the 19 lit segments of 12:09 in seven-segment display.
The start 12:0 has 13 segments, then 0>6, 1>2, 2>5, 3>5, 4>4, 5>5, 6>6, 7>3, 8>7, 9>6.
