The Jiarengrad Clock Tower

The Jiarengrad Clock Tower is a redstone clock tower, located in Jiarengrad, Azerath Nations. The Jiarengrad Clock Tower was built to house an experimental clock mechanism, which used Daylight Sensors, invented by Harrs Vulschven, a renowned redstone engineer and inventor. Vulschven intended to show off the mechanism so it could be used in every nation of the Azerath Nations. Despite Vulschven's plans, the Jiarengrad Clock is the only redstone clock in the Azerath Nations.

Invention
In 2D 020, Harrs Vulschven commissioned the construction of a tower in the middle of Jiarengrad, Azerath Nations, to house an invention he made a year prior. The invention was the Daylight Sensor and Vulschven decided to implement the sensor into a redstone clock. Originally, Vulschven wanted the tower to be much smaller but the size of the mechanism made that prospect impossible.

It took 3 years for the tower to be completed and the mechanism to be installed. Vulschven unveiled the clock tower to an audience made up of businessmen from all over the Azerath Nations and the crowd was not impressed with the tower. However, they were impressed with Vulschven's Daylight Sensor, which sold out fast. Although the tower was a failure, Vulschven's invention of the Daylight Sensor made him an extremely successful and rich inventor.

Mechanism and usage
The Jiarengrad Clock Tower is an extremely simple and basic time telling mechanism. At sunrise, the bottom lights illuminate while the top lights stay dark. At noon, both top and bottom lights illuminate. At sunset, the bottom lights are illuminated while the top lights are off and at night, none of the lights are illuminated.

The purpose of the clock is to tell businesses when to open and close. In Jiarengrad, all businesses are required to base their open/closed times on the clock. When the lights come on at sunrise, it is time for businesses to open. When the two lights are on at noon, it is time for lunch (businesses can take lunch breaks at any time for any amount of time while the two lights on the tower are lit). When the bottom lights are on at sunset, it's time for businesses to close and when the lights are off at night, businesses should be closed.
