SETUP TIME ZONE
This menu lets the user enter the names of the local time zone with daylight saving
disabled and enabled, together with the zones´ time offsets from UTC. The left part of
the display shows the zone and offset if daylight saving is off whereas the right part
shows name and offset if daylight saving is on. These parameters are used to convert
UTC to local time, e.g. MEZ = UTC + 1h and MESZ = UTC + 2h for central europe.
The range of date daylight saving comes in effect can be entered using the next two
topics of the setup menu.
SETUP: TIME ZONE
DAYLIGHT SAVING OFF: !MEZ ! +01:00h
DAYLIGHT SAVING ON : !MESZ ! +02:00h
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.
