JPClock is an application designed to reproduce a Japanese clock (Wadokei) used in the Edo period (1603-1867).
The Wadokei is a Japanese clock used to count time by dividing the day in six units from sunrise to sunset, and by dividing the night in six units from sunset to sunrise.
The temporal hour is a traditional Japanese timekeeping practice that was established with the lifestyle of the Edo period. Work while the Sun is up, and the day ends at sunset.
The oil used for home lighting was expensive in this period. Living with the sun cycle was economical.
JPClock uses the iPhone's GPS function and measures your position (latitude/longitude) in order to reproduce the Japanese clock.
It also contains a normal clock and a calendar, so you can use the application as a desktop clock or calendar.

* Time zone will be set according to the "date and time" settings of the iPhone/iPod touch.
* The latitude/longitude of some areas may not be measured with the iPod touch.
Please check the availability of the auto measurement with the Apple's "Maps" application.
If the area is listed in JPClock's built-in locations, you can measure latitude/longitude even when the auto measurement doesn't work.
* The Wadokei(Japanese clock) cannot be used when the latitude/longitude is not specified.
(Normal clock and calendar are available.)
* The altitude is not included when calculating sunrise/sunset time.
The latitude/longitude calculated by GPS might have a margin of error.
Hence, it could create an error for each time.
* When Screen lock is set to off, the application won't sleep.
When using the device as a desktop clock for a long time, please make sure the device is plugged in the charger.
