• Displays local time plus preset world cities in the dropdown menu
• Shows each location's time zone identifier, UTC offset, and local date
• Refreshes automatically every second
• Includes a footer row with Quit on the left and Settings on the right
• Lets you control top-line date, weekday, clock style, blinking separators, and seconds from Settings
• Lets you choose the dropdown date format and whether the app launches at login

Preset Clocks

The app currently shows:

• Local time zone
• San Francisco
• New York
• London
• Berlin
• Shanghai
• Tokyo
• Sydney

You can edit the preset list in TimezoneBarApp/StatusBarController.swift.

Requirements

• macOS 13 or later
• A recent Xcode version with Swift/AppKit support

Run In Xcode

1. Open TimezoneBar.xcodeproj.
2. Select the TimezoneBar scheme.
3. Press Run.

The app launches as an accessory app, so it appears in the menu bar instead of the Dock.

Build From The Command Line

xcodebuild \

Signing Notes

The project currently includes a preset bundle identifier and development team in the Xcode project. If you are building this outside the original environment, update Signing settings in Xcode before creating a distributable build.

For local compile-only verification, the command-line examples above disable code signing.
