Oh dear. I enjoyed the original version... Now there is no challenge to look forward to when trying to guess the correct time... But I do so like Roman Numerals... Eventually, if modifications continue, press a specific key and the computer will "tell" you the time... I miss the guessing *sigh*
You sound like you'd love a Roman Clock.
The Romans used 24 hour days, but they kept time from sun rise to sun set. On the first day of summer, we have about 14 hours of daylight. On the first day of winter, there's only about 10 hours of daylight.
The difference in Roman time and modern time is that these hours aren't based on a whole day being broken down into 24 one-hour chunks. The Roman day was 12 hours daylight, 12 hours darkness -- so the length of those 12 hours of daylight were about 70 minutes long in summer and only 50 minutes long in winter....
Which sounds like any modern clock that used Roman Time would certainly require a LOT of guessing!
