NEW GEOCLOCK DATA FILES
FOR DAYLIGHT SAVING TIME CHANGES
Summer 1990
This set of files (1) provides a new GECONFIG.DAT with daylight saving time
for spring and summer 1990, and (2) updates certain GEO*.DAT files to match
changed DST designations in GECONFIG.DAT.
You should replace your GEO*.DAT files with those in this set if you are
using the data files distributed with the registered version of the Geoclock
program. Otherwise, you might look at them and the new GECONFIG.DAT file, to
determine whether any changes are necessary.
The GECONFIG.DAT file has daylight saving time for 1989-90 (southern
hemisphere) and 1990 (northern hemisphere), covering cities in the GEO*.DAT
files distributed with the registered version of Geoclock. It also has a time
zone for New Zealand, in response to popular demand, plus time zones for
eastern Canada and the western Aleutian Islands of Alaska.
There are two changes in the data files. South Korea does not observe
daylight saving time. It was previously shown with a DST zone, but apparently
this was a one-time occurrence for the Olympics in 1988. Australia has two
sets of DST zones. New South Wales and Queensland go off summer time on March
4. Victoria, South Australia, and the capital territory keep summer time for
two more weeks. Western Australia and Northern Territory do not observe summer
time.
This set of files includes cities for Map 31 (USSR) and Map 54 (Canada), in
case you do not have them. As a bonus, I have added North Cape (Norway), the
northernmost point in western Europe, and Wellington (New Zealand) to the
GEOCLOCK.DAT file.
By the way, neither the GECONFIG.DAT nor the GEOCLOCK.DAT has all of the
good information in "REM" form. Also, GECONFIG.DAT does not have VGA or SVGA
codes. These files are keyed to the Eastern Time Zone. So compare your
current files with the new ones before replacing them.
If you have any question on these or other Geoclock data files, or on time
zones, drop me a message on the Geoclock Bulletin Board, or telephone me at
home.
