ZuluBarGitHubNative macOS menu bar utility
Keep UTC in sight. Add the cities you work with, then copy any clock’s time with one click.
Signed, notarized, and maintained by one person. One-time $5.
Click any clock to copy its time.
The global shortcut always copies UTC. Search, add, remove, or reorder city clocks from the native time-zone picker.
For logs
Keep UTC visible while you compare server logs, deploy events, incident notes, and support messages.
For teams
Keep UTC as the shared reference and add your teammates’ cities alongside it, without doing the time-zone math.
For notes
Paste display time, Unix timestamps, or RFC 3339 values without reaching for another tool.
Designed for production work
Keep Zulu time in the menu bar, updating every second, without opening a calendar or converting from local time.
Search by city or IANA zone, then add, remove, or reorder two-line clocks. Each city follows its own daylight-saving rules.
Click any clock to copy its local time. Your global shortcut always copies UTC, no matter which cities you add.
Use Z, UTC, no suffix, optional date prefixes, Unix timestamps, or RFC 3339 depending on where the time is going.
A small sandboxed macOS app with no accounts, no dashboards, no telemetry, and no background product surface to manage.
The paid app is signed, notarized, and updated automatically, so you do not have to rebuild for routine fixes.
Open source, paid convenience
ZuluBar is MIT licensed and fully buildable from source. The paid build removes distribution friction: signing, notarization, and automatic updates are handled for you.
