My major pain with f.lux is the inability to manually specify when it should start shifting colours. I work in a brightly lit office until way after the sunset (esp. in winter), and it makes no sense for my screen to start colour shifting at 5PM.

My current 'solution' is simply manually starting f.lux when I get home, and killing it when I go to the office. Tedious!

Lie!

Tell F.lux it you live on the equator in the settings. If it's triggering too early, move your fake location west.

That's one way to do it in winter, if exactly 12 hour days suffice, and don't move too much. Manually adjusting the longitude every time I fly to the US would be a pain though.

What I'd really like is to tell it 'turn yourself off at sunrise, turn yourself on at sunset or 2100, whichever's later'.
