Assuming a 12 hr clock, I thought it would be 1:23,
but really it would be 0:12, right?
To calculate:
12:12 = 11:72
04:56 = 04:56
-----------------subtract
---------7:16, 7 hrs, 16 min when it happens again
That's 7(60) + 16 = 436 min

The next time would be: 5:67 - which is 6:07, but a digital clock will not display this. It can't be 0:12 because a digital clock doesn't display that either.
Therefore, it MUST be 1:23, and when 4:56 is subtracted from 1:23 (13:23 in military time), we get: 13:23 - 4:56 = 8:27, or 8(60) + 27, or
