GlobalClock

This is a clone of PM Globe2; famous software for IBM OS/2. You can get original PM Globe2 for OS/2, PM Globe3 for Windows and Palm Globe for Palm from here. Global clock has enhanced clock function including DST support. Global clock uses neigher DirectX nor OpenGL.

Features

You can see globe from any direction and change its size.
Any points on globe can be at center by clicking the point.
Show name and local time of a city at its point on globe. DST (Daylight Saving Time) is supported.
Draw day and night area based on clock. Your city will be dark at night in real world.
For experts, surface of globe, cities (name and time) can be configured.

Requirements to run

I checked Global clock runs with condition below.

OS	Japanese Windows 2000, XP
CPU	Intel Pentium4 2.4GHz, Intel Mobile Pentium III 733MHz/500MHz, AMD AthlonXP 1800+
Video	Hi-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.

Install

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

GlobalClock.exe
GlobalClock.ini
default-map.ppm
default-font.pgm
default-font.txt

Uninstall

Delete all files above. No Windows registry is used.

Usase

You can change size and view direction by changing parameters listed on right. Try globe on top of this page.

Longitude	Longitude of center point to show. Positive number for east and negative for west.
Latitude	Latitude of center point to show. Positive number for south and negative for north.
Rotation	Rotate globe in Windows desktop plane. Positive number for CCW. North pole will be at top with 0.
Size	Radius of globe (unit: pixel). It requires memory in propotion to square of radius.
Cities	Selected cities will be drawn on globe. Any cities behind of globe will not be shown.
Save	Record 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.)
Redraw now	Redraw globe right now. Globe is updated automatically every minute.

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.
