I have just installed 188.8.131.52 and find that it calculates sun set/rise times incorrectly. This error may have been in earlier versions but I cannot be sure.
My location, Leeds England is given Lat 53 deg 45' and Lon 1 deg 30' which is correct. Daylight saving time is used and correctly dated as +60 min on 25th Mar.
Comfigurator calculates Sunrise as 4:19 and sunset as 19:45 on 5th May for example
The actual values are Sunrise as 5:23 and sunset as 20:44
Comfigurator calculates Sunrise as 4:19 and sunset as 19:45 on 5th May for example The actual values are Sunrise as 5:23 and sunset as 20:44
The times displayed in sunrise/sunset are without the effect of daylight saving
Hence if daylight saving is in effect, the times have to be increased 1 hour, so the "real" sunrise would be 5:19 and sunset at 20:45 which is very close to what you say are the correct times.
The cities.csv file contains the data for sunrise and sunset times used in Comfigurator.
