The change from summertime to wintertime, and vice versa, is made automatically. The
date of the earliest changeover can be readjusted should the relevant regulations
change.
The dates set for the change from wintertime to summertime, and vice versa, ensure
that on the first Sunday after that date, the time of day will change from 02:00 (winter-
time) to 03:00 (summertime), and from 03:00 (summertime) to 02:00 (wintertime).
If both dates are set to coincide, summer- / wintertime changeover will be inactive.
