About GeoClock
GeoClock shows the current time (based on your computer's clock) with a high quality map of the earth. The current sun position is displayed, and the parts of the earth in sunlight and twilight are highlighted. This display is automatically updated every few seconds. Local sunrise, sunset, the sun's azimuth and elevation, and times around the world are also displayed. A variety of map backgrounds and other options are available.
GeoClock is distributed as shareware. With registration you get the latest versions of the programs, 45 maps, zoom, distance measuring, local time displayed next to the city names, and immediate map display. GeoClock comes in DOS and Windows versions, and both are included with registration. The Windows version works with Win3.1x, WFW, Win9x, WinME and WinXP. The Windows version also includes Screen Saver and Wallpaper modes.
The Windows version requires a VGA and 4 MB, but we recommend at least 800x600x256 display and a 486/66. It will run on both Win3.x and Win9x/ME/XP.
We do not have versions for any other platforms.
GeoClock comes in a basic version and a professional version, and both are available with a HAM radio add-in package.
GeoClock-Pro includes both the registered DOS and Windows versions of GeoClock, plus more than 500 maps covering each US state, Canadian province, and world country, plus about 150 city level maps, and a variety of larger scale maps, the spinning globe program, about 100 extra maps (these are unsupported and may be of unique interest, but are included just because some people want everything), and a variety of utility programs to customize GeoClock data bases. It is distributed on CD, or can be downloaded.
The GeoClock basic includes both the registered DOS and Windows versions of GeoClock, plus 45 maps covering the world at a larger scale. It is distributed on CD, 3.5 inch floppy disks, or can be downloaded.
A HAM radio package is available as an add-in to either package. It is distributed on 3.5 inch floppy disks or can be downloaded, or included on CD if the basic or Pro package on CD is ordered at the same time.

This file contains the latest version of the GeoClock time zone table. This is the regular "spring" update of the GEOZONES.DAT file. The biggest news in time Zones is that Venezuela has changed from GMT-4 to GMT-4 1/2. This is described as a permanent change. It was apparently effective on January 1, 2008. This file has a GeoClock time zone for Venezuela. Also, the Dominican Republic has changed. You will also need to incorporate changes to several GeoClock map data files (included in this ZIP) to implement the change. No daylight saving time is involved. The United States and Canada observe daylight savng time from the second Sunday in March to the first Sunday in November. This began in 2007. This year's dates are March 9 - November 2, 2008. Mexico did not change from the former dates.
All European countries observe summer time on March 30 - October
26, 2008.

This intermediate version of the GEOCKWIN.EXE which seems to solve some stopping problems and clock problems on ME, XP, NT5, and 2000, and changes to the internal ZIP data base for Indiana. It includes only the EXE and HLP files, so you will need all the other GeoClock files to test it. It is little different from BETA84B. Please advise results. See FAQ. |
