This looks like a typo since the numbers are backwards from what I expect: 6 pm to 6 am

Well, I actually put those numbers in to match what I see right now. What is the default manual settings for other programs like redshift/flux?
I couldn't find source code for f.lux. For Android, the manual default is from 10 pm to 6 am. https://android.googlesource.com/platform/frameworks/base/+/master/core/res/res/values/config.xml#787 The manual default for redshift is the coordinates for Newark, New Jersey, US. On the Spring Equinox there, sunset is 7:10 pm, sunrise is 6:58 am. https://github.com/jonls/redshift/blob/master/redshift.conf.sample#L39 https://www.google.com/search?q=newark%2C+new+jersey+sunrise+march+21 I don't know if redshift is using sunrise and sunset times. If we used "astronomical twilight", we get 8:42 pm and 5:26 am. https://www.timeanddate.com/sun/usa/newark?month=3&year=2017 I proposed 6 pm and 6 am, assuming solar noon would be 12:00 (it's actually about 1:00 pm in Newark).
What Jeremy's suggesting sounds about right to me. I'd maybe start a bit later in the evening (8pm, say), but that's a detail.
Okay, with 8pm please push to master. Thanks!
