The general rule is:
+ means east of,
-
means west of the Greenwich Meridian.
In the upper line the old value saved is displayed.
Since most countries in the world select their time difference in full hours, the input is also in
steps of one hour.
e.g. + 05.00 ; - 11.00
However some countries move in time zone steps of half an hour. Here the input is com-
pleted with minutes.
e.g. + 05.30 ; - 08.30
4.3.3 Time Zone Changeover
Selection frame:
CHANGE-OVER DATE S - > D AND D -> S
S = STANDARD TIME D = DAYLIGHT TIME Y / N
Input frame:
S --> D hh.d.w.MM D -> S_hh.d.w.MM
- >_ . . . <- -> . . .
With this input it is possible to enter the points in time at which there is a changeover from
daylight saving or standard time in the course of a year. The hour and the month at which
the changeover should take place are entered. The exact times are calculated automatically
from the date of the current year.
S
D
the entered changeover time is valid for the changeover from Standard time
(winter time) to Daylight Saving Time (summer time)
D
S
the entered changeover time is valid for the changeover from Daylight Saving
Time (summer time) to Standard time (winter time)
Both changeover times in the year can now be entered between the arrows.
If no Daylight Saving Time has been introduced at the location of the system or no change-
over is required, then a 0 (zero) should be assigned to all these values, so that an S for
standard time can be shown in the display as a time zone abbreviation. After the changeover
times have been entered the Master Clock System calculates the exact changeover time to
the nearest minute change and adopts these new values.
The individual inputs have the following meaning:
hh
= the hour at which the changeover should take place 00 .. 23 h
d
= the day of the week on which the changeover should take place
1 = Monday ... 7 = Sunday
w
= shows in which week of the month the changeover should take place
1 ... 4 means 1 ... 4 week in the month
5 last week
MM
= the month in which the changeover should take place
