I have a digital clock that shows the time (hours and minutes, in standard AM/PM format) as four digits. Each digit is formed by lighted segments: digits from 0 to 9 have 6, 2, 5, 5, 4, 5, 6, 3, 7, and 6 segments respectively. If the leftmost digit should be a "0", a blank is shown instead.
What's the earliest time when the sum of the segments equal the sum
of the digits comprising the time? The latest time? The time with more/less lighted segments?

i guess i didn't understand the third part. i took it to mean 'at what time are the most/fewest lighted segments lit?' I suppose a more interesting question would be 'of the times when the two quantities are equal, what is the most/fewest number of lit segments?' To the latter version, i guess:
