Unix time is the number of seconds elapsed since midnight UTC on January 1, 1970. It is the de facto timekeeping format inside most computers because it is compact, easy to compare with simple arithmetic, and free of the ambiguities that human time formats carry around (time zones, daylight saving, calendar variations). The tradeoff is that no human can read it at a glance. This converter does the translation in both directions. Paste an integer to see it interpreted as both seconds and milliseconds, then rendered in UTC and your local timezone. Or paste an ISO 8601 date to see the corresponding Unix timestamp. The tool also shows the current Unix time updating each second, which is handy when debugging logs or scheduling reminders. Conversion runs in your browser using the standard JavaScript Date object, so the results match what any modern web service or server-side JavaScript runtime would produce.
Frequently asked questions
Unix time is sometimes recorded in seconds and sometimes in milliseconds. The convention varies by language: most Unix tools use seconds, JavaScript's Date.now() returns milliseconds, and many databases use whichever convention the application chose. A number around 1.7 billion is seconds; a number around 1.7 trillion is milliseconds.
