why do you use the clock? The romans wanted to know the time silly billy
If you didnt have a clock you would be late or early for stuff and have to ask other people for the time alot. If no one had a clock people would probably use the sun to tell time. But an economy of such complexity as ours would have a more difficult time operating.
Some people have used it for many many years. Most still use the 12 hour clock, although for some special applications they might use the 24 h version.
A 24 hour clock is better when you are running around the clock operations. Military, Police and Fire Stations use it to avoid any confusion when talking time. Factories that run around the clock, shipping companies, and airlines use it. Answer The Aviation and Space industries use the 24 hour clock as well. It reduces confusion, especially when written or oral communications are critical

The egyptians I believe with the sundial as a clock also the first people to believe in one god and that god was the sun.
Some alarm clocks are programmed to use a human voice for the "wake-up call". A cuckoo clock "sings"... Any clock will tell you the time, if you can read it's face.
