Timezones

Timezones keeps your clients, teammates, and cities aligned around the same instant. Drag one tactile timeline and every tracked timezone moves with it—complete with daylight-saving changes, fractional offsets, working-hour context, and an optional quiet dial sound.

Requirements

macOS 14 Sonoma or newer

Build from source

git clone https://github.com/taras-creates-things/Timezones.git
cd Timezones
open Timezones.xcodeproj

In Xcode, select the Timezones scheme and My Mac, then press Run. The app is menu-bar-only, so it will not appear in the Dock.

Using the timeline

Drag the ruler or scroll horizontally over it to shift every city together.
The orange range measures the distance between now and the selected time.
Click the target button to animate smoothly back to the current time.
After focusing the ruler, use Left/Right Arrow to move by 15 minutes; hold Shift to move by one hour.
Use the plus button to add a city and the settings button to adjust appearance, time format, home timezone, launch behavior, and sound.
Drag city rows to reorder them, or secondary-click a row to copy, edit, move, or remove it.
