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. Traditional Japanese time divides the day and night into six equal periods from dawn to dusk and dusk to dawn respectively. 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. 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. 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. This kept the time shown on the clock reasonably close to the correct time, provided that the clock had been set correctly initially. This modern implementation is much more accurate and precise than the original clocks. In this implementation, the biweekly adjustments of the mechanical clock are made continuously, thus the day or night period length are always correct. Noon on the clock will, if location services are enabled, occur when the sun is at the zenith, or solar noon. Day start and end correspond to the beginning or end of twilight, and are calculated accounting for the refraction of the Earth's atmosphere. There are three situations where the clock my not show the local time in the Japanese manner: 1. If location services are off, Daimyo Clock will show the time for Tokyo, Japan. 東京 will be displayed on the clock face in this case. 2. While the application is obtaining an updated location after launch or returning to foreground. 3. Near the North or South poles the sun may either be above the horizon or below it for the entire day (24 hour period). In this case, the Japanese definition of time no longer applies, so the clock face will be shown without a clock hand.

Color-Clock is a unique clock that translates time into color. The more hours, the more red, more minutes more green, more seconds more blue. Every second a different color! Give your old cell phone a new life as a stylish desk clock. No sim card needed. It will run all day on airplane mode, even with the screen always on. Share a particular beautiful color as png with your friends. The RGB values will be added too, so you can use it later in your own designs. Manipulate time with the Science Fiction mode. Challenge your friends: who can be the first to share the clock showing the time from one hour ago? HOW IT WORKS The dial continuously changes color throughout the day. Red indicates the hours, green the minutes, and blue the seconds. The values range from 0 (dark) to 255 (bright) – just like in design software. For example: it is 8:40 and 20 seconds. 8 hours is one-third of 24 hours, so red is one-third of 255. 40 minutes is two-thirds of 60, so green is two-thirds of 255. And 20 seconds is one-third of 60, so blue is one-third of 255, or 85. But wait, one second later, blue is 89! Once you get used to it, you may look forward to the colors in a particular part of the day. COLOR SCHEMES Switch between six color schemes: RGB, RBG, GRB, GBR, BRG, and BGR. Each scheme assigns the three color channels to hours, minutes, and seconds in a different order, creating a completely different color palette for the same moment. FEATURES - Analog clock with colored hands that correspond to the active color scheme - RGB value display showing the exact color composition - Six color schemes to choose from - Speed modes: 3x, 15x, 60x, 300x and 500x to see colors change quickly - Freeze mode: pause to capture a color you like and share it. - Share: share the current clock as a PNG image - SF (Science Fiction) mode: switching between color schemes does not change color, but time! - Picture-in-Picture: keep the clock visible as a floating window - Always On: keep the screen active as long as the app is open - Full screen: now the clock stands out beautifully DESIGNED BY Color-Clock is designed by Peter Ritmeester / PZZL.com — known for innovative puzzles and brain games.
