SETUP DAYLIGHT SAV ON/OFF
The two topics let the user enter the range of date for daylight saving to be in effect.
Concerning parameter input both topics are handled identically, so they are described
together in this chapter. Beginning and ending of daylight saving may either be
defined by exact dates for a single year or using an algorithm which allows the
receiver to recompute the effective dates year by year. The figures below show how to
enter parameters in both cases. If the number of the year is displayed as wildcards
(´*´), a day-of-week must be specified. Then, starting from the configured date,
daylight saving changes the first day which matches the configured day-of-week. In
the figure below March 25, 2000 is a Saturday, so the next Sunday is March 26, 2000.
All changeover rules for the daylight saving like "the first/the second/the second to
last/the last Sunday/Monday etc. in the x-th month," can be described by the used
format "first specified day-of-week after a defined date".
If the number of the year is not displayed as wildcards the complete date exactly
determines the day daylight saving has to change (March 28, 1999 in the figures
below), so the day-of-week doesn´t need to be specified and therefore is displayed as
wildcards.
SETUP: DAYLIGHT SAV ON
DAYLIGHT SAV ON Date: 25.03.****
Day Of Week: SUN Time: 2:00:00
SETUP: DAYLIGHT SAV OFF
DAYLIGHT SAV OFF Date: 25.10.****
Day Of Week: SUN Time: 3:00:00
If no changeover in daylight saving is wanted, an identical date and time must be
configured in both of the submenus (see fig. below). In addition identical offsets for
DAYLIGHT SAV ON/OFF should be configured in the submenu TIMEZONE.
