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.

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).
