UNIX Timestamp Converter

Convert UNIX Timestamp to a human-friendly format without online tools. DevUtils.app allows you to quickly turn a UNIX Timestamp into a human-friendly format. You can also inspect more information from the datetime like relative time (e.g., xx minutes ago), ISO formatted string, or check the current date of the week, week of the year, etc...

Convert UNIX timestamp

You can convert timestamps from anywhere in your macOS (terminal, in email, web browser,...). Activate the app by:

  • Copy text ► Press Space
    (Or your own customized hotkey, up to you)
  • Copy text ► Click to iconDevUtils.app status bar icon in the status bar
  • Select text ► Right-click ► "Inspect in DevUtils.app"
    (This menu appears after you install the app)


Unix Time Converter received one input. The input can be in the following format:

  • Standard UNIX timestamp (seconds since epoch).
  • Milliseconds since epoch.
  • ISO date format.
  • The tool also tries to parse the input using popular formats like yyyy/mm/dd when possible.

You can also use the "Now" button to set the current timestamp, which is very convenient when you need to grab the current timestamp as a string.


If the input is valid, the following information will be returned in the output:

  • The datetime rendered as local time in human-friendly format.
  • The datetime in ISO 8601 format.
  • The relative time compares to the current time (e.g., 3sec ago).
  • The UNIX time format: for when the input is in ISO format.
  • Day of the year.
  • Week of the year.
  • Whether the year is a leap year or not.


When you activate the app, DevUtils will inspect your clipboard content and automatically select the UNIX Timestamp Converter if the content is a valid UNIX Timestamp that falls within a certain range.
