Daimyo Clock for Android

11 things about Daimyo Clock

1. Daimyo clock is a recreation of a mechanical clock developed in the seventeen century based on western clocks but modified to show traditional Japanese time.

2. Unlike Western clocks which are regulated by a single pendulum and run at a constant speed day or night, Japanese clocks incorporated two pendulums, and switched between them at dawn and dusk.

3. In this implementation, the biweekly adjustments of the mechanical clock are made continuously, thus the day or night period length are always correct.

4. Traditional Japanese time divides the day and night into six equal periods from dawn to dusk and dusk to dawn respectively.

5. If location services are off, Daimyo Clock will show the time for Tokyo, Japan.

6. This kept the time shown on the clock reasonably close to the correct time, provided that the clock had been set correctly initially.

7. Noon on the clock will, if location services are enabled, occur when the sun is at the zenith, or solar noon.

8. Over the course of a year as the daylight and nighttime periods lengthen and shorten, the length of these six day or night periods change.

9. Adjustment for the changing daylight and nighttime hours was accomplished by adjusting the effective length of the pendulums, normally done every two weeks, or twenty-six times a year.

10. 東京 will be displayed on the clock face in this case.

11. This modern implementation is much more accurate and precise than the original clocks.
