UnixTime: Timestamp Converter - Unix Epoch / Timestamp Converter for the Mac Menubar

by•
The last timestamp converter you'll ever need. UnixTime converts Unix epoch timestamps and dates in your Mac menu bar. Seconds, milliseconds, microseconds, nanoseconds, ISO 8601, .NET Ticks and FILETIME. Smart Conversion handles quotes, brackets and field names. Convert with a click or keyboard shortcut, append results without replacing the original, and preserve nanosecond precision. Custom date formats and dates before 1970 included. Fully offline. No account or subscription.

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.

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

Really appreciate that! Menu bar > browser tab for something you use 20 times a day. The history was one of those "why doesn't every tool do this" moments while building it, so I'm glad it clicks for you too.

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.

Thanks so much! That was exactly the idea behind it – no browser tab, no tracking, just a quick lookup right from the menu bar. Good to hear the custom format ordering actually pays off in real-world debugging – that's what I built it for.

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.

Anything you'd love to see in the next update? Always happy to hear what would make it even more useful in your workflow. Is there anything missing that would make it perfect for you? Batch conversion, more formats, shortcuts, iCloud sync… all on my radar, but I'd love to hear what you'd prioritize.

Update v1.0.4 for UnixTime is out now with many improvements:

  • New timestamp formats: UnixTime now supports many more formats: microseconds and nanoseconds, .NET Ticks, Windows FILETIME/LDAP, Chrome/WebKit, Cocoa/NSDate, HFS+ (classic Mac), Mozilla PRTime, and Julian Day Number. Show or hide any of them with a single click in Settings.

  • Any format as your default: You can now set any timestamp format as the default — no longer just seconds or milliseconds.

  • Unlimited custom date formats: Create as many custom date formats as you like, give them your own names, and edit or delete them right in Settings. Month names appear in the app's language.

  • History with source app: The history now shows which app a value was copied from — including the app icon and name. Now you see where the timestamps came from.

  • Redesigned info tooltip in the menu bar: Hover over the menu bar icon to instantly see what's on the clipboard and what a click will copy.

  • Unit next to the timestamp: Timestamps now display their unit (s, ms, ns …) right beside the value — in the tooltip, the copy confirmation, and the calculator.

  • Exact sub-second precision: The current timestamp is now captured exactly — including microseconds and nanoseconds, matching your chosen format.

More improvements

  • Random timestamps now always stay in the past (no more future values).

  • Date calculator: input fields follow the order and separators of your default date format.

  • Many UI and usability improvements: one-click focus on open, consistent field highlighting, better tooltips, more room, smooth scrolling, and polish throughout.

UnixTime v1.0.6: Smarter timestamp conversion. Every digit intact.

Copying a timestamp from a log, JSON or source code rarely gives you just the number. You get quotes, a trailing comma, a field name or a few extra spaces. UnixTime now handles those details for you.

  • Smart Conversion recognises values like "1785407677", ts=1785407677 and Java or JavaScript numeric literals. When replacing a value, it preserves surrounding quotes, brackets, field names and whitespace.

  • Keep the original. The new Convert & Append shortcut adds the readable date after your timestamp, so the raw value stays available for searching and debugging. Choose parentheses, brackets, a comment marker or your own separator.

  • Preserve every fractional digit. Custom date formats now display milliseconds, microseconds and nanoseconds without rounding. Useful when the difference between two log entries is smaller than a second.

  • Go back before 1970. Convert negative timestamps to dates and back.

This update also fixes whitespace disappearing during replacement and invisible characters blocking recognition.

All in your Mac’s menu bar, with customisable keyboard shortcuts. Fully offline, with no account or subscription.

Which timestamp format or workflow should I tackle next?
