Setup Daylight Sav On/Off - Meinberg LANTIME/GPS Operating Instructions Manual

SETUP DAYLIGHT SAV ON/OFF

These 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 re-compute 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, 1996 is a Saturday, so the next Sunday is March
31, 1996.
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 31, 1996 in the figures
below), so the day-of-week does not need to be specified and therefore is displayed as
wildcards.
DAYLIGHT SAV ON
Day of Week: Sun
DAYLIGHT SAV ON
Day of Week: ***
DAYLIGHT SAV OFF
Day of Week: Sun
DAYLIGHT SAV OFF

If no changeover in daylight saving is wanted, identical dates and times must be
entered in both of the submenus. In addition identical offsets for DAYLIGHT SAV
ON/OFF should be configured in the submenu TIMEZONE. After this a restart
should be done.
