new products -- a clock for grid daylight/night-time

[Fred T. Hamster]

a clock for grid daylight/night-time:

we need a special time keeping device that shows a proportional day/night ratio to sl light schedule.

should work for opensim too.

query time of day vs night,

find out where in timing it is,
make two discs, one colored all night, one all day color.
show a portion of the night disc that's proportional to its actual ratio to day.

(have the cylinder cut values do this for us)
