Honestly whenever I want to farm Eidolons and see that I need to wait an hour for it to turn to night or that I night ends in 20min I just don't bother. Not a problem with Fortuna and Deimos because the cycle is so short with Fortuna and the Deimos doesn't really matter but PoE has a 2h rotation iirc (1h 20min of day, 40min of night).
