You're absolutely right that "100% right" is an unreasonable standard. I submit that knowing that there are places on the planet where, at times, the sun doesn't set, however, is a reasonable thing to expect of someone who's made it far enough in life to be writing code (or testing it! How did this pass QA?) for Apple.

f.lux gets it right if I set my zip to Barrow, AK. Why can't Apple, with how many orders of magnitude more resources at their disposal — including knowledge?
