Requirements to run

I checked Global clock runs with condition below.
OSJapanese Windows 2000, XP
CPUIntel Pentium4 2.4GHz, Intel Mobile Pentium III 733MHz/500MHz, AMD AthlonXP 1800+
VideoHi-color (16bit) True color(24bit/32bit)
You may be see bad colored globe with video less than them.
It must run well on Windows for any language. It should run well on Windows 95 and 98. Note that it requires 6MB memory on Windows 2000 for drawing radius 300.


Put these files in same directory/folder and launch GlobalClock.exe.


Delete all files above. No Windows registry is used.


You can change size and view direction by changing parameters listed on right. Try globe on top of this page.
LongitudeLongitude of center point to show. Positive number for east and negative for west.

SaveRecord latitude, longitude, radius, window position and city selection to globalclock.ini. This record will be restored on next launch. (Globe at top of this page does not have this function.)

Any points on globe can be centered by clicking the point. Window size can be changed with same manner of most Windows application. Globe radius will be changed to be suitable to new window size. Cities are colored with this rule.
