3.6.1.3 Daylight Saving panel
The Daylight Saving panel allows the configuration of the points in time for the beginning and
the end of the daylight saving time. If daylight saving time shall not be applied the "DST
Changeover" checkbox must be deactivated.
The parameters are configurable in such a way that the changeover may be applied at any
point in time.
If the DST Changeover checkbox is deactivated local time is calculated without considering
daylight saving time. The calculated local time corresponds to standard time which is defined
by the time zone offset applied to UTC time.

Sometimes the setting of the last day-of-the-week in December may lead
to erroneous results and is therefore not permitted!
