Re: Simple Calculation of Sunset Time required

[Rodney Blackall]

Having (thankfully!) missed most of this topic it seems that someone wants
something to switch on at dusk and off at dawn.

1. There is a big difference in "lighting up time" between clear evenings 
/mornings and cloudy ones which will be tricky to program in.

2. There are optical sensors which will cope with the task of switching when
the ambient light level crosses a preset threshold without recourse to
correcting for leap seconds.
