I got confused

I calculated these 3 sunsets:

Pearl Harbor
Date: 07/10/44
157°59w 21°14N
sunset=18:24
SunAlmanac= shows a latitud of 10° at that hour. For 21°, sunset should be at 18:43

Starry night= visually shows sunset at 18:45

Brisbane
Date: 06/11/42
153°51E 27°9S
sunset=17:12
SunAlmanac=calculating time/degrees between 20° and 30° in SunAlmanac, you get exactly 17:12 :p
Starry night= visually shows sunset at 17:14

Perth
Date: 03/16/43
114°56e 32°11s
sunset=18:44
SunAlmanac=Shows a latitud of aprox 70° at that hour. For 32°, sunset should be at 18:16

Starry night= visually shows sunset at 18:18
