gensky time

Hi All,

Just a quick question. How does time work in gensky? It seems to accept
values which are not realistic. For example

gensky 3 20 14.8 -a 40 -o 98 -m 105 > sky.rad

If I assign the time as 14.8 it produces a sky for that particular time
which of course is not possible. I need to know because I'm writing a
script to produce a sun animation (1 frame = 1 minute) and I need to
know whether values such as above are meaningful or if I should set the
script so that values for minutes are allowed only between 0-60.

The same goes for the hours.. It accepts any value larger than 24!

Cheers,
Patrick

No, that's perfectly valid. You can assign time in hours:minutes, or as decimal hours, like your example. 14.8 would be 14:48 (2:48PM).
