Daylight saving time/standard time changeover
The controller changes automatically from daylight saving to standard time.
The data can be changed to the earliest possible time change since the
corresponding standards may change.
The dates set for the change from standard to daylight saving time, or vice versa,
ensure that on the first Sunday after that date the time of day changes from 02:00
(standard time) to 03:00 (daylight saving time), and from 03:00 (daylight saving
time) to 02:00 (standard time).
Switch off daylight saving/standard time changeover by setting both data to the
same day.
