UnixTime
The Story
UnixTime is a fast, native macOS menu bar app for converting Unix timestamps (epoch time) to human-readable dates and back — from seconds and milliseconds to microseconds, nanoseconds, and many platform-specific timestamp formats.
Description:
UnixTime lives in your menu bar and makes working with Unix timestamps effortless. Just hover over the menu bar icon and a tooltip instantly shows what is currently on your clipboard, its matching counterpart (the corresponding timestamp or date), and exactly what a click would copy — all before you click anything. A single click then copies the converted result to your clipboard, ready to paste wherever you need it. If your clipboard is empty, a click copies the current timestamp in your chosen format instead.
Conversion works in both directions and is detected automatically: copy a timestamp to get a date, or copy a date to get a timestamp. Beyond the classic Unix seconds and milliseconds, UnixTime also handles microseconds, nanoseconds, and a range of platform-specific epoch formats used by .NET, Windows, Chrome/WebKit, Apple, Mozilla, and classic Mac systems, as well as the astronomical Julian Day Number. Each timestamp is shown together with its unit (s, ms, ns, and so on) so there is never any doubt about what you are looking at.
A built-in date and time calculator lets you build and adjust specific moments in time: enter a date, add or subtract seconds, minutes, hours, days, weeks, months or years, switch between time zones, and generate random dates or times for testing. Every conversion is saved to a history list — including which app you copied the value from — so you can copy any previous result again with a single click.
You stay in full control of the interface. Show, hide, and reorder any format, set your preferred timestamp or date format as the default, and create as many custom date formats as you like, each with its own name and pattern. The app is fully localized in 12 languages.
AI Overview
AI-generatedDevelopers working with Unix timestamps face a recurring friction: converting between epoch time and human-readable dates typically requires opening a browser, finding a converter, and pasting back and forth. UnixTime, a native macOS menu bar app, eliminates this workflow entirely by placing timestamp conversion directly where developers already spend their attention—in the menu bar.
The core interaction is immediate. Hover over the menu bar icon to see what's on your clipboard, its conversion counterpart, and what a single click will copy, all before committing to the action. Click left to perform a conversion or copy the current timestamp if the clipboard is empty. Right-click to see all available output formats at once, customizable through drag-and-drop to show only what matters. The app operates completely offline, never transmitting data outside the local machine.
What distinguishes UnixTime is its comprehensive format support. Beyond the standard Unix seconds and milliseconds, it handles microseconds, nanoseconds, and platform-specific formats used by .NET, Windows, Chrome, WebKit, Mozilla, Apple, and legacy Macintosh systems. It even converts astronomical Julian Day Numbers. Timestamps appear with their units labeled, eliminating ambiguity about scale.
A built-in date and time calculator moves beyond simple conversions. Users can construct specific moments by entering dates, adjusting values by seconds through years, switching time zones, or generating random dates for testing purposes. Every conversion gets logged in a searchable history tied to the source application, so previously converted values can be retrieved and recopied without re-entering data.
Customization is thorough. Users control which formats appear and in what order, set preferred defaults for timestamp and date output, and create unlimited custom date formats with unique names and patterns. The app respects macOS appearance settings, automatically following light and dark modes or locked to either.
Localization spans 12 languages, and the business model is straightforward: a 2.99 euro one-time purchase with no subscription, advertisements, or data collection. The result is an app built directly for how developers actually work—minimizing context switching and reducing unnecessary steps in a task they perform hundreds of times.
