Alter sunrise/sunset calculation #5

Open kelnage opened 5 years ago

kelnage commented 5 years ago

The sunrise/sunset calculation obtained from Wikipedia seems to work pretty well, but it also generally seems to be about 5 minutes off the time provided by the Garmin widget.

Who is right? Who knows! One option would be to check with alternative sources - but I imagine users would prefer consistency and I doubt I'll be able to convince Garmin that my calculations are better than theirs, so I should probably look at altering them.

Potentially could use code from https://github.com/haraldh/SunCalc - need to look into LGPL2 and GPL3 compatibility.
