UnixTime - Unix timestamps for humans — native, instant, no nonsense.

by•
Most Unix timestamp tools are buried in a browser tab or wrapped in Electron. UnixTime is a native macOS app that does one thing well: convert timestamps, fast. Built-in timestamp math, full conversion history, custom formats with drag & drop ordering. No account, no subscription, no in-app purchases. Buy once, use on all your Macs. For developers who open a timestamp tool a dozen times a day and just want the answer immediately.

I kept reaching for online timestamp converters while debugging — paste a number, get a date, close the tab, repeat. Every existing tool was either a website (slow, stateless, gone when you close it), an Electron app pretending to be native, or part of some bigger utility suite I didn't need. So I built UnixTime as a proper native macOS app. The goal was simple: it should be faster to use than opening a browser tab. Instant launch, menu bar access, history so you don't lose conversions mid-debugging session. The timestamp math feature came from a real pain point — I kept manually calculating "what's now + 3600 seconds" in my head or in a separate calculator. Now you just type it in. What surprised me during development was how much the small details matter for a tool you use this frequently. Getting the format ordering right, the hide/show toggles, the drag & drop — none of that is technically hard, but it's the difference between a tool you reach for and one you forget about.

Hey everyone,

just pushed v1.0.1 of UnixTime — a small but solid update:

  • Added French, Spanish, and Italian localizations

  • Fixed tooltips that were completely broken in menu bar apps (turns out macOS never activates NSTooltipManager for .accessory-policy apps — had to build a custom overlay system from scratch)

The tooltip fix was the annoying one. If you hovered over any icon in the toolbar or sidebar, nothing happened. Should work properly now across all three buttons.

Would love to hear what you think — especially if you're using one of the new languages and something looks off in the translation. Also open to feature requests for v1.1: what would actually make this more useful in your day-to-day workflow? Drop it below or hit the feedback link inside the app.

native macos app for timestamps feels long overdue, the drag and drop format reordering is a nice touch and the history saves me from retyping the same conversions

drag and drop for custom formats is genuinely clever, and the native macOS feel makes it way nicer than juggling a browser tab. finally something that fits how i actually work.

Love that it stays out of the browser entirely. The custom format ordering is a small touch but it actually saves me from alt-tabbing to figure out which log line is which.
