How it works

1. 1

   Paste a timestamp, or press Now.

2. 2

   Read the local and UTC dates.

3. 3

   To go the other way, pick a date and time.

4. 4

   Copy the seconds or milliseconds value.

About the Unix Timestamp Converter

Logs, databases and APIs record time as Unix timestamps, the number of seconds or milliseconds since 1 January 1970 UTC, which no one can read at a glance. This converter turns a timestamp into a readable date in both your local time zone and UTC, and turns a date you pick back into seconds and milliseconds. It works out whether a number is seconds or milliseconds on its own.

What you can do

• Paste a timestamp in seconds or milliseconds; values of 13 digits or more are treated as milliseconds.
• See the matching date and time in your local time zone and in UTC.
• Press Now to load the current timestamp.
• Pick a date and time to get its Unix timestamp in seconds and milliseconds.
• Copy any result with its own button.

When it works best

• Reading created_at or exp values from a database row, log line or JWT.
• Working out when a cache entry, signed URL or token expires.
• Writing a timestamp into a test or API call for a specific date.

Things to know

• Conversions use your browser's clock and time zone settings, and nothing is sent to a server.
• Local time follows the time zone of your device, so a colleague elsewhere will see a different local result for the same number.
• Only whole numbers are accepted. Negative values for dates before 1970 work, but fractional seconds and date strings in the timestamp field do not.
• To read the exp claim in a token first, use the JWT Decoder. For schedules, use the Cron Parser.
