The time switch switches on at the calculated sunset time and off
at the calculated sunrise time.
By setting an offset, you can shift the switching times by up to
±120 minutes with respect to the calculated sunrise and sunset
times.
Example:
If you set the offset to +30 minutes, the time switch will switch 30
minutes after sunrise and 30 minutes after sunset. If you set the
offset to -30 minutes, the time switch will switch 30 minutes
before sunrise and 30 minutes before sunset.

If the offset setting is in degrees the time switch switches on
and off at times of equal brightness, despite the differences in
twilight time lengths over the course of the year.
Sunrise and sunset correspond to -50' for the centre of the sun
(the edge of the sun is visible on the horizon).
