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, WinXP, Vista, Win7, and win8. The help system does not run in vista or later. The GEOCKWIN.EXE runs on 16 and 32 bit OS's, and the GEOCKW32.EXE runs on 32 and 64 bit OS's. We have been a bit disapointed by the quality of beta testing, so problems probably will be found in the GEOCKW32.EXE version. The only new feature added to the W32 version is a secure (encrypted) email registration procedure.

System Requirements

The DOS version requires a VGA and 640K, and will run on an 8088. However, we recommend at least a 386SX/25 for satisfactory performance. The Spinning Globe program runs best under DOS with at least 4 MB Extended/Expanded Memory and a 486/25

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, and with limitations (help system, time control, screen size) vista, win7, and win8.

We do not have versions for any other platforms.

Packages

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.

ACE-HF

ACE-HF (Animated Communications Effectiveness, High Frequency) is a new product based on the proven VOACAP program with a new interface and display routines based on GeoClock. Click the icon to read more about ACE-HF.

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.
