IANA time zones: Choose from the complete database, find time zones with search and pin frequently used ones as favorites. Daylight saving time is calculated for the date and time being converted.
Choose the format directly: Switch between seconds, milliseconds, microseconds, nanoseconds and other formats in the converter. Your selection stays in sync with Settings.
Relative time: Every conversion now includes context such as “3 hours ago” or “in 2 days”. Custom formats can use the new placeholders R, RR, RY, RM, RW, RD, RH, Rm and RS – from a compact direction to individual time units.
Live “Now” clock: An optional toggle keeps the current time live while you use UnixTime. Updates pause automatically when the app is inactive.
Edit timestamps directly: The converter field is now editable and uses a monospaced font. It accepts only digits and, where needed, a leading minus sign. The maximum length adapts to the selected format.
Nanoseconds without precision loss: Nanosecond values of up to 19 digits stay exact throughout the app – when parsing and formatting, in history, through keyboard shortcuts and in placeholders.
Nanosecond precision without rounding: numeric input timestamps retain fractional seconds. Custom date formats offer SSS for milliseconds (3 digits), SSSSSS for microseconds (6 digits), and SSSSSSSSS for nanoseconds (9 digits).
Smart conversion recognizes timestamps and dates surrounded by spaces, tabs, line breaks, brackets, quotes and punctuation. Replacing text
directly with a shortcut preserves those surrounding characters, even with an imprecise selection.
Field names such as ts= or created_at: stay in place when replacing a value. A colon is treated as an assignment only when preceded by a field name, so times such as 12:34:56 are not split apart.
Invisible stray characters (Zero Width Space, Non-Joiner, Joiner, Word Joiner and BOM), Java type suffixes L/l and the JavaScript BigInt suffix n are removed.
New: Convert & append with ⌘⌃⌥V. Keep the selected text and add the result after it. Choose parentheses, square brackets, an arrow, // or #, or set your own prefix and postfix with an instant preview in Settings.
Negative Unix timestamps are now supported. Conversion also works in reverse: a date before January 1, 1970 produces a negative timestamp.
UnixTime launches as a native Unix timestamp converter for the Mac menu bar.
Help shape UnixTime
What would make it your last timestamp app?
Missing a format, an easier workflow or a setting? Found something that does not work as expected? Please email me. I build UnixTime and welcome the details that help me make it better.
Have a wishlist? Tell me what you need and how it would help your workflow. A short example is especially helpful. I decide which ideas to build and in what order, based on how well they fit UnixTime. Some suggestions may not make it into the app: keeping it focused, fast and easy to use matters too.
