World Time Wallpaper

A night-world-map wallpaper paired with a live Rainmeter clock strip for ten cities.

Python / PillowRainmeterPowerShell / Windows

Preview

Night Earth map, UTC guide lines, and a row of ten city clocks — Static preview. The installed Rainmeter overlay updates the clocks on the desktop.

Night Earth wallpaper with star field and UTC guide lines, without the clock overlay — Clean wallpaper used beneath the live overlay.

How it works

A Python script generates the map wallpaper from NASA Earth city-lights imagery. The Rainmeter skin draws the clock strip over the wallpaper and updates the displayed times.

PowerShell scripts install the skin, create a Windows startup shortcut, and check every five minutes that Rainmeter and the overlay are running.

Scope and credits

The preview is a saved image, not a browser-based live clock. The current Rainmeter skin uses fixed UTC offsets, so cities that observe daylight saving time need seasonal offset changes.
