WorldTime for Windows (Version 1.1 - 9/20/91 release) Documentation Introduction ------------ WorldTime for Windows (ver. 1.1) is an easy-to-use worldwide clock utility that runs within the Microsoft Windows 3.0 environment. WorldTime displays the current local time, Greenwich Mean Time, and the time in each of the five continental U.S. time zones. In addition, two user-selected controls display the current time in any of over 100 metropolitan and geographic locations around the world. Finally, a user-defined control allows time display for a completely user-customizablelocation. All configuration settings can be saved so as to be in effect each time the program is run. ("Microsoft" and "Windows 3.0" are registered trademarks of Microsoft Corp.) Program Files ------- ----- The WorldTime package consists of three files: WTIME.EXE, WTIME.INI, and WTIME.TXT. WTIME.EXE and WTIME.INI comprise the program itself; the WTIME.TXT file contains program information, notes, and a registration form. The main program file, WTIME.EXE, obtains configuration information from WTIME.INI each time the program is run, and writes any changes in your configuration to WTIME.INI each time you exit the program. For this reason, both files should be stored in the same directory when running WorldTime from a hard drive. Program Notes ------- ----- WorldTime for Windows requires Microsoft Windows 3.0 or higher. Although WorldTime runs acceptably on systems equipped with EGA or Hercules graphics, we strongly recommend the higher resolution available on a VGA (color or mono) system. WorldTime's relatively low memory overhead (~90 Kb) and modest screen refreshes make its performance satisfactory on virtually any computer capable of running Microsoft Windows 3.0+. WorldTime Setup --------- ----- Setup and configuration for WorldTime is fairly straightforward. The most important thing to do BEFORE running WorldTime is to make sure your computer's system clock (DOS TIME and DATE) settings are accurate. This can be done from the DOS prompt with the "TIME" commmand, through the use of several popular setup utilities, or (perhaps most conveniently) within Windows itself via the Control Panel. For WorldTime to function correctly, your local time zone must be selected (active) in the Local Time Zone list box control. Once this is done, all WorldTime calculations will be based on your computer's system clock, relative to Greenwich Mean Time (GMT). This selection need only be made once (assuming your computer is not moved to a different time zone). Once configured, WorldTime displays your local time, Greenwich Mean Time, and the current time in the five major continental U.S. time zones. Two User-Selected drop-down controls allow you to display the current time in any of 110 locations around the world. A third control is completely User-Defined, allowing you to enter a custom location of your own choosing. Time setting in the User-Defined Location is controlled by the horizontal scroll bar (which may be blanked by setting to the extreme left position). All configuration settings, including local time zone, User-Selected and User-Defined locations and times, are saved into the WTIME.INI file when you exit WorldTime. Note: Changes in your configuration will ONLY be saved to the WTIME.INI file if you exit via the "File/Exit" menu bar sequence. Closing WorldTime by double-clicking the control button in the upper-left corner (or using the Alt-F4 key combination) will exit the program WITHOUT saving any new settings. Daylight Savings Time Mode -------- ------- ---- ---- New to this release of WorldTime for Windows is a user-enabled Daylight Savings Time mode. If Daylight Savings Time is in effect in your local time zone, WorldTime should be run in DST mode. DST mode is toggled on and off via the menu bar "Options/DST Mode" selection; when active, it makes the necessary adjustments to WorldTime's calculations (again, assuming the user's computer system clock has been accurately updated to reflect the correct current time). DST Mode "active" status is confirmed by a RED indicator located just to the right of the WorldTime globe logo. Calculations for recognizing foreign (i.e. non-local time zone) Daylight Savings Time periods -- and there are SEVERAL in use in different parts of the world -- are handled within the program itself, and do not require user-configuration. As with the other configuration settings, your local DST Mode status is written to WTIME.INI and maintained in effect for subsequent sessions. Daylight Savings Time Irregularities -------- ------- ---- -------------- Daylight Savings Time is officially observed in the United States from the first Sunday in April to the last Sunday in October. Even so, there are certain areas within the U.S. and its territories that DO NOT observe Daylight Savings Time. These include the states of Arizona, Hawaii, parts of Indiana, the commonwealth of Puerto Rico, and the Virgin Islands. As mentioned in the previous section, many countries in the world observe some form of Daylight Savings Time. Unfortunately, the dates of observance differ widely from nation to nation (and, in the case of some countries in the Southern Hemisphere, occur at the opposite time of year). Although WorldTime is capable of recognizing the Daylight Savings Time periods observed in each of the nations listed in the User-Selected Location controls, this requires that both the TIME and DATE settings of your computer's system clock be correct. Note: The Greenwich Mean Time display always reflects true Standard Time at the Prime Meridian, even during those periods when locations in that time zone are observing Daylight Savings Time. For this reason, the displayed GMT time will, during such periods, actually differ from clock times shown for locations like London or Manchester, U.K., which obviously lie in the GMT+0 time zone. In some other countries, the "official" policy regarding Daylight Savings Time is extremely flexible, and subject to periodic change. Future releases of WorldTime will attempt to reflect any such changes. Upgrade Notice ------- ------ Release 1.1 of WorldTime for Windows represents a number of changes to the internal code of the original version, as well as the manner in which configuration information is handled. For this reason, owners of the previous release should NOT use their old (ver. 1.0) WTIME.INI file with the new WTIME.EXE program. In case of confusion, the WTIME.INI file can be displayed with Windows Notepad (or any DOS text editor or file browser). Line one of the correct Release 1.1 INI file should include the following bracketed text: [WTime1.1]. Please do not edit or overwrite the INI file while viewing!
