Alter sunrise/sunset calculation #5
Description
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.
