About the Timestamp Converter

Logs and databases store time as a number of seconds or milliseconds since the start of 1970, which is efficient for machines and unreadable for people. This converter translates in both directions and shows the result in your local time, in UTC and in ISO 8601 form.

It also detects whether your input is in seconds or milliseconds, which removes the most common source of results that are off by a factor of a thousand.

  1. 1Paste a timestamp to convert it into readable dates, or pick a date and time to get a timestamp.
  2. 2Check whether the tool detected seconds or milliseconds.
  3. 3Read the local, UTC and ISO representations.
  4. 4Use the current-time button when you need the timestamp for right now.
