Not only has the time of sunrise and sunset shifted. They are expanded far too much with a longer daytime in your example. Around the 26th of september is the equinox. Meaning duration of night and day should be the same. So if it is sunrise at 10:01 it would be expected to be sunset at 22:01-ish. Sunrise in Lorient, France on 23rd of September in 1940 was actually 08:01 and 20:09 local time.
