Hi Foeke I know two examples in Japan, time-mark stones, which was used for the water distribution to rice field. The one is the noon-mark stone, which was built 350 years ago and used for the distribution of irrigation water on alternate days. The other is the time-mark stone of 150 years ago, which indicates the time of the Sun's elevation angle, around 12 degrees, before sunset. The regulation is that the daytime-distribution is from the sunrise to the time and the nighttime-distribution is from the time to the sunrise. At the place this system devides the whole day equally about the middle of August.
